Oversize Threshold and Freight Impact

Email from Regina Marrone on 7/23/25

Hi Team,

I want to send a quick reminder about unit width limits, prompted by the upcoming shipment of '''Load E883''', which was built at '''144.5 inches wide'''.

'''Why This Matters:'''

Any load over '''102 inches (8 feet 6 inches)''' in width is considered '''oversize (OD)''' in every state. That means even if a unit is 103" wide, it's subject to:

:'''• Permitting requirements'''

:'''• Daylight-only travel restrictions'''

:'''• No weekend or holiday movement''' in most jurisdictions

:'''• Route restrictions''' and bridge/clearance checks

We try to keep all units at '''143 inches or less''' because '''144 inches (12 feet)''' is a critical regulatory threshold. Once a load hits 144" or more:

:'''•''' It enters a higher risk/penalty category

:'''•''' Many states begin to require '''escort vehicles'''

:'''•''' Freight costs rise significantly due to extra coordination, permits, and escorts

'''Real-World Example – Load E883:'''

Load E883 was built at '''144.5" wide''', pushing it over the 12-foot mark. As a result, it now requires:

:'''• Permits in every state along the route'''

:'''• Escort vehicles''' in several states

:'''•''' Compliance with '''restricted travel hours'''

:'''•''' An estimated '''$1,000–$1,500 increase in freight cost'''

This one example highlights why we don’t build right up to the 144" limit — there’s no margin for error, and the smallest overage can have significant downstream impact.

'''Design Guideline:'''

:'''•''' Please '''design and quote units at 143" or less'''

:'''•''' Coordinate early with Transportation if wider designs are being considered

:'''•''' Verify final specs before release to avoid costly oversize surprises

Thanks for your attention to this. Even one inch can make a big difference when it comes to shipping efficiency, compliance, and cost.

Greenheck Blower Options

Return to [[Engineering|Engineering Main Menu]]
Greenheck Plenum Blower Options

Note from CCB on 3/10/25: If an all-aluminum blower is required, the use of Twin City Fans is acceptable.

Email from Clay Brown to Engineering on 2/29/2024 

'''Subject:''' Aluminum Plenum Blowers

Pricing from TCF is coming in significantly lower than Greenheck for the all-aluminum plenum blowers. Please make you are specifying the stainless steel hardware for coastal/corrosion protection is required. When possible, continue to request a quote from Greenheck so we can check on a number of different sizes. Many of the blowers for Publix will be the same so we would not need to continue to check the price on these in most cases. Also make sure that they are including a lead time on the quotation. Just like Greenheck, we may have to make some motor substitutions to keep lead times in line.

Updated 05/09/22

Greenheck DOES make the following:

*Arr. 3 (belt drive) horizontal plenum blowers

*Arr. 4 (direct drive) horizontal plenum blowers

*Housed Arr. 4 (direct drive) horizontal (FAN CELL) plenum blowers

*Arr. 4 (direct drive) vertical plenum blowers (up to 40" Class I and II)

*All aluminum Arr. 4 (direct drive) horizontal plenum blowers (up to 33" Class I and II and up to 20 HP motor)

 

Greenheck DOES '''NOT''' make:

*Arr. 3 (belt drive) vertical plenum blowers

*All aluminum plenum blowers that are:
**Vertical Arr. 4
**Belt drive (horizontal or vertical)
**Class III
**> 33" wheel size
**> 20 HP (1200 RPM)

 

Email from Clay Brown to Engineering on 10/21/16 

'''Subject:''' Greenheck Blowers

Just want to remind you that we want to use Greenheck blowers as much as possible in lieu of Twin City. We have had a number of bearing failures this year with TCF, they have had issues building fans correctly, and the customer service has not been great. That being said, we must strive to maintain a working relationship with TCF because we still rely on them for aluminum construction blowers and vertical belt driven plenum blowers. Not to mention that we are seeing cost and labor savings with the Greenheck APH belt drive assemblies.

 

<s>As of November, 2016</s>,

<s>Updated 6/17/21,</s>

<del>''Greenheck blower list moved to top of wiki page (9/23/21, TDM)''</del>

''Added vertical DD size limitation (VTH,5/9/2022)''

Email from Clay Brown to Engineering on 4/24/20 

'''Subject:''' Aluminum Construction for Blowers

 

Please note that the options that state “FAN TO BE ALUMINUM CONSTRUCTION (option #23016, #23026)” are intended to specify an ALL aluminum construction, meaning wheel , inlet cone and frame. Currently, Twin City and Comefri are the only suppliers that we have for all aluminum plenum blowers, and Comefri’s offering is only available up to 28” diameter. Twin City has had several late deliveries so we want to use them only when absolutely necessary. We are working with Comefri’s engineering to get their product added to the ERP, but at the moment you have to use the manual option in the ERP.

Greenheck’s APH does have an aluminum wheel, and an aluminum inlet cone is available (standard is steel). There is an option in Pro-5 for aluminum wheel (option #23051), so if only an aluminum wheel if required, we can use Greenheck.

When all aluminum construction is requested for weight reduction, we need to pursue other options an use the all aluminum blower as a last resort. The all aluminum construction in addition to the lead time concerns is quite expensive. Our goal should be to minimize the use of all aluminum construction blowers as much as possible. Sales will continue to request all aluminum construction for “extreme coastal” units.

If we have preliminary design that become factory orders with the Twin City blowers, we need to try and change these blowers to Greenheck or Comefri. In many cases, we have been able to change from TCF all aluminum to Greenheck and make some adjustments to the weight to keep the same weight from the submittal.

Please let me know if you have one of these designs, and I will work with you to see what we can do. If we do determine that TC is our only option, then we will need to release the blowers as early as we can to help with lead time.

As a reminder, Greenheck does NOT manufacture a BELT drive VERTICAL plenum blower (Direct Drive only).

Accumulators in Supermarket Equipment

Return to [[Engineering|Engineering Main Menu]]
Email from Clay Brown on 7/31/23  

I wanted to send out an update on our accumulators. We will continue to following the rules listed below.  I took care of quite a few jobs that were in production, but I want to make sure that all of you are continuing to make these update to jobs as you are creating the production packages, bills of materials and submittals. We want to use these rules on any unit where we can to reduce the demand on the accumulators until things hopefully settle down with Westermeyer.

 

Also (this part is new), if we do find ourselves completely out of the accumulators, we will remove accumulators as needed. We will not delay any equipment due to lack of availability of accumulators. Any time this situation arises, please get with me to review.

 

''We will ELIMINATE accumulators on any PC or RA circuits with the following EXCEPTIONS:''

 

*''We will continue to provide accumulators for any tandem or 50% hot gas reheat circuit on any split system.''

 

*''We will continue to provide accumulators on any circuit with 50% hot gas reheat.''

 

*''We will continue to provide accumulators on any DEHUMIDIFICATION circuit with a tandem compressor.''

 

*''We will continue to provide accumulators on any water cooled system with tandem compressors.''

 

''This will apply to all Supermarket customers, including Publix. This will start immediately and will be retroactive on everything in Production that has not started in piping. You will begin to see emails from me for specific factory orders detailing the changes required.''

PE Schedule Guidelines

Email from Tim Morris to Engineering on 6/25/20

Subject: PE Schedule Guidelines

 

The recent automation that we were finally able to add to the PE Schedule has been a huge game changer. Clay and I are now able to review jobs, add new jobs to the schedule and make start date updates about 3 to 4 times faster and more accurate than before. The only down side is the fact that, since it is a shared excel file, our major updates can easily get overwritten by other user updates. As we discussed in last week’s meeting, please do not keep the PE Schedule open for an extended period of time. If you do have it open for a long time, do not save the file. The new approach really needs to be open the file, get what you need, then get out.

We would like to start following these guidelines until we are able to incorporate the PE Schedule directly into the ERP.

 

'''1)  If you open the PE Schedule and do not make any changes, do not save the file.  Close without saving.'''

 

'''2)  If you open the PE Schedule and are not certain if you made any changes, do not save the file.  Close without saving.'''

 

'''3)  If you had the PE Schedule open for longer than 30 minutes, do not try to make any changes or save the file.  Close the file without saving.  You can then reopen, make your changes, save, and close the file.'''

 

I appreciate your help and patience with this. Honestly, you can keep the file open all day, but just don’t save it. I am try to figure out why the PE Schedule keeps resetting the major scheduling changes, so with all of us following these few procedures, hopefully we can figure out why. I know Excel is not the ideal platform for the department scheduling, but it is the best thing we have right now and really easy to use. Could be worse; could be in Pro-5.

 

Thanks everyone. If you have any questions or do not understand these new issues with the PE Schedule, please give me call.

Factory Order Status Codes

2022-03-21T13:43:21Z

Timm:

Return to [[Engineering|Engineering Main Menu]]   '''Policy and Procedure Bulletin number 1, Open Factory Orders'''
 Bulletin number 1-2, Definition and use of status codes assigned to open factory orders

 Effective date: 05/16/06        Latest revision: 03/10/08        Issued by: LBW

 Purpose: To define and explain use of factory order status codes

 Purpose of revision dated 3/10/08: To add and define status code 09 and status code 50. To clarify existing status codes as needed.

 Two digit numerical codes have been used to indicate status of factory orders since the beginning of the factory order (FO) system. This bulletin is a reminder and clarification of how they are used. The sales department initiates the determination of the correct status code.

 '''Status code 08:''' Status 08 should be assigned to factory orders (FO) that have not been allocated any production time on the production calendar. Therefore, no commitment has been made for an onsite date. These jobs have a “coded” start date of 08/08/18 and the complete, ship and on site dates are blank. Engineering may work on these jobs to provide information for sales and the customer but a status 08 job will not be committed. In some situations Engineering may prepare a bill of material (BOM) for 08 jobs but the work order (WO) will not be committed. While status 08 jobs are expected to eventually turn into orders, they are lacking in information and/or approvals to the extent that Seasons 4 is unwilling to “set aside” valuable production time for them.

 It is important for sales to recognize that an onsite commitment should not be made for status 08 jobs since production time has not been reserved to meet a specific date.

 '''Status code 09:''' Status code 09 is assigned for jobs that have been allocated production time on the production calendar and an onsite commitment has been made to the customer. These FO’s have “real” start, complete, ship and onsite dates in the FO system. However, there is significant information or approvals needed and these jobs will not be processed to completion and parts ordered. For example, any job without a PO will not be processed beyond status 09. Engineering, based on their scheduling and information available, may commit parts by initiating a WO but purchasing will not order parts for any jobs in status 09.

 If, for whatever reason, processing cannot be completed on a timely basis for a status 09 job and it has been committed by engineering it should be changed to status 15. If it has not been committed it can be changed to status 08. Status 09 jobs have to be processed timely in order for parts to be ordered and received by the start date. The FO has to be changed to status 10 in order for purchasing to order parts.

 '''Status code 10:''' Status code 10 is assigned to jobs that can be processed to completion including building the equipment. Once a job becomes status 10 and the work order committed it should not be changed to status 08 or status 09. If a delay is necessary it should be changed to status 15. If a status 10 job has not been committed then it can be changed to status 08 or 09 but once the work order is committed it can only be changed to status 15.

 Purchasing will order parts for status 10 jobs. In fact, barring special situations or instructions, status 10 is the only type FO that purchasing will order parts for.

 '''Status code 15:''' Code 15 signifies a job is on hold and it may or may not continue Work should cease on status 15 jobs until the situation is clarified and the status code is changed. This code can be used before a job is committed but is always used to delay a job once the work order has been committed. The program automatically inserts 12/15/15 as the start date on all status 15 jobs. Purchasing recognizes this code and will not order parts that haven’t been ordered. If they have been ordered, purchasing will consult with sales to determine if:

*It is a temporary situation and orders should be put on hold but not cancelled;
*Orders should be cancelled;
*Cancellation charges, if any, should be invoiced to the customer;
*Parts that are received and it is unlikely they will be used can be invoiced to the customer.

 '''Status code 40:''' This code signifies a job has proceeded through the test station but is not ready to ship to the customer. For example, it may be waiting installation of a part that has not been delivered. Status 40 is assigned by the plant manager of the respective plant.

 '''Status code 45:''' This code signifies a job is complete and ready to ship to the customer. Code 45 jobs are considered finished goods inventory. It is assigned by the plant manager of the respective plant.

 '''Status code 50:''' This code is assigned when a FO is shipped and billed. The FO is transferred to the service system at this time and ceases being in the FO system. The person preparing the invoice assigns code 50 and transfers the FO. In a pre bill situation the status code does not change.

Subject: Humidifier Piping for Plant Steam (Dri-Steem grid, no generator by Seasons-4)

All,

See the attached drawing per our discussion in the last engineering meeting regarding steam piping for humidifier. As we discussed, the Y-strainer and modulating valve must be located within 3 feet of the grid per Dri-Steem. The Y-strainer and control valve should be at the same height or higher as the steam grid inlet to avoid water lock in the line. This drawing also includes some additional notes for mounting of the control valve and the Y-strainer (see also below). Please note that the Y-strainer should be mounted horizontally with the cleanout to the side rather than pointed down as we do for water piping.

 

Victor did an excellent job pulling all of this information together, so we should be able to refer to this drawing for future projects.

Special Engineering Document Intent

2022-01-27T22:14:02Z

Timm:

Return to [[Engineering|Engineering Main Menu]]
Purpose:

To inform, explain, and call out project requirements TO PRODUCTION that are outside the scope of “normal” procedures and policies or constructions. While other departments may look at the SE document, it’s not meant as a place for instructions to drafting or sales or service.

 

Definitions:

Normal- This is almost purely subjective and changes based on unit type and category. What’s normal for supermarket is different that what’s normal for custom. Same with indoor air handler versus outdoor roof top unit.

 

Manager’s Intent:

The PE should employ critical thinking in the creation of this document. Balancing the need for expediency with the need to clarify project requirements. Avoid direct duplication of FO options and SE’s but expand and clarify any options or SE’s that could be confusing or misinterpreted on the floor. Call out items that are unique to the project or are critical to customer satisfaction. Items that could be expensive repairs if not installed (or not installed correctly) in production.

 

Create a document that improves the chance that Seasons 4 will produce a quality product.

 

Examples:

Control panel muffin fans- There is a production procedure that covers the installation of muffin fans when there is a single control panel but nothing that directs production when more than one CP is in the unit. If you have two panels, call out where the muffin fans are installed. Production should ask but this will increase the odds that someone gets it right (or discovers it if it’s wrong).

Flat base frame- This unit has a FLAT base frame. 95% of the formed bases S4 builds have the integral flashing. This may be the only place that it would be visible outside of engineering and drafting.

Change to a common design- The previous four units had viewports. This unit does NOT have viewports.

 

Theory:

In theory, everyone should do their job to 100% perfection. Each department should read the FO, SE, weight sheet, and any other info that’s available for the project and they should make their checklists and hold themselves accountable.

 

Reality:

Everyone has bad days, tired days, missed days, …

If there’s something that you’re on the fence about adding to the SE because it’s “someone else’s job” to see the info or check the info, take a break then go ahead and add it.

 

Food for thought:

If A has the right of way but both A and B go and collide, did anyone win?

Flat base frame- This unit has a FLAT base frame. 95% of the formed bases S4 builds have the integral flashing. This may be the only place that it would be visible outside of engineering and drafting.

Change to a common design- The previous four units had viewports. This unit does NOT have viewports.

 

Theory:

In theory, everyone should do their job to 100% perfection. Each department should read the FO, SE, weight sheet, and any other info that’s available for the project and they should make their checklists and hold themselves accountable.

 

Reality:

Everyone has bad days, tired days, missed days, …

If there’s something that you’re on the fence about adding to the SE because it’s “someone else’s job” to see the info or check the info, take a break then go ahead and add it.

 

Food for thought:

If A has the right of way but both A and B go and collide, did anyone win?

'''Subject:''' Electronic Expansion Valves for Copeland ZPV compressors

 

Effective immediately, all circuits with a Copeland ZPV variable speed compressor will have an electronic expansion valve for improved superheat control. Sales has been notified to include this on all factory orders, but if they have missed it, please make sure to have them add it to the factory order. Only the ZPV circuit will get an EEV, unless specified otherwise in the factory order.

EEV Selection:

The EEV selections do NOT have any over capacity built in to the Sporlan program like the TXV’s, so it is recommend that EEVs be selected for 90% maximum rating. It is important to keep in mind that you do not have to be as concerned with the valve being “oversized” for EEVs as the valve’s control is consistent through the range of operation.

'''Subject:''' Electronic Expansion Valves for Copeland ZPV compressors

 

The first group of teardown reports on the Copeland ZPV compressors show lack of lubrication as the suspected cause of failure, but the several most recent teardowns indicate dilution/washout/slugging as the mode of failure. The end result of both of these failure modes is similar, but the latter shows evidence of liquid back to the compressor. Liquid back to the compressor indicates a loss of superheat control.

To provide better superheat control across the wide operating range of the ZPV compressors, all refrigerant circuits with a ZPV compressor will be provided with an electronic expansion valve going forward. These valves more expensive than a thermostatic expansion valve, but the data suggests that the EEV is more appropriate choice to prevent liquid refrigerant back to the compressor. Unless required by the project specifications, standard single stage, digital or tandem compressors will have a standard thermostatic expansion valve.

Please make sure that this is included in all future quotes and factory orders for units with ZPV variable speed compressors.

'''Subject:''' Greenheck Blowers

Just want to remind you that we want to use Greenheck blowers as much as possible in lieu of Twin City. We have had a number of bearing failures this year with TCF, they have had issues building fans correctly, and the customer service has not been great. That being said, we must strive to maintain a working relationship with TCF because we still rely on them for aluminum construction blowers and vertical belt driven plenum blowers. Not to mention that we are seeing cost and labor savings with the Greenheck APH belt drive assemblies.

'''Subject:''' Aluminum Construction for Blowers

 

Please note that the options that state “FAN TO BE ALUMINUM CONSTRUCTION (option #23016, #23026)” are intended to specify an ALL aluminum construction, meaning wheel , inlet cone and frame. Currently, Twin City and Comefri are the only suppliers that we have for all aluminum plenum blowers, and Comefri’s offering is only available up to 28” diameter. Twin City has had several late deliveries so we want to use them only when absolutely necessary. We are working with Comefri’s engineering to get their product added to the ERP, but at the moment you have to use the manual option in the ERP.

Greenheck’s APH does have an aluminum wheel, and an aluminum inlet cone is available (standard is steel). There is an option in Pro-5 for aluminum wheel (option #23051), so if only an aluminum wheel if required, we can use Greenheck.

When all aluminum construction is requested for weight reduction, we need to pursue other options an use the all aluminum blower as a last resort. The all aluminum construction in addition to the lead time concerns is quite expensive. Our goal should be to minimize the use of all aluminum construction blowers as much as possible. Sales will continue to request all aluminum construction for “extreme coastal” units.

If we have preliminary design that become factory orders with the Twin City blowers, we need to try and change these blowers to Greenheck or Comefri. In many cases, we have been able to change from TCF all aluminum to Greenheck and make some adjustments to the weight to keep the same weight from the submittal.

Please let me know if you have one of these designs, and I will work with you to see what we can do. If we do determine that TC is our only option, then we will need to release the blowers as early as we can to help with lead time.

As a reminder, Greenheck does NOT manufacture a BELT drive VERTICAL plenum blower (Direct Drive only).

Administration/003 Adminstration Production Package Policy.pdf

2021-02-25T19:41:00Z

Timm:

Return to [[Engineering_Procedures|Procedures Main Menu]]
Index: Administration

Subject: (3) Production Package Policy

Date: October 12, 2000

''Revised January 5, 2021''

 

When preparing the production package for a unit, it is essential that the project engineer ensure that all the information provided is the most current information available. The production package completion date will be as assigned by the Engineering Manager, typically two days prior to the production start date as shown in Pro-5. (The OMS checksheet will be completed at the same time as the production package, see OMS manual engineering procedure for additional information). After the production packages are complete, the project engineer will enter the production package completion date in Pro-5 and in the PE schedule.

 The project engineer will transmit the production package to the Engineering Department Administrative Assistant (EDAA). The EDAA will print all current factory orders from Pro-5 and add them to the production package. It is still recommended that the project engineer print a new copy from Pro-5 and review it carefully to make sure that the production package includes all revisions.

 

Each unit on the factory order must have its own production package. The production package cover sheet should indicate the individual work order number and unit designation (where applicable) for each unit. The EDAA will scan the complete production package for each unit and save them in the Production Package folder for the project on the FO ( J:) drive.

 

The special engineering sheet for the production package will be created as a Word document and saved in the [[FO_(_J:)_drive]]“Special Engineering” folder. The file name will indicate the factory order number or work order number where multiple special engineering sheets are required (EX: “J:\A300-A399\A374\Special Engineering\A37401_SE.doc”). If any revisions are made to the special engineering sheet, the revision date shall be listed at the top of the document directly below the original creation date. All revision dates shall be maintained and not overwritten so that the total number of revisions is shown. A template file to create the Special Engineering document can be found in H:\EngMstr\Special Engineering Template.doc. '''The Special Engineering document will be created at the same time as the unit bill of materials.'''

 

When changes need to be made to the production package after it has been issued to production, changes can be e-mailed to the Supervisors Plant 1 or Supervisors Plant 2 Outlook distribution lists, and copied to the Engineering Manager and VP of Engineering, as well as any other individual that may be directly affected by the revisions. The project electrical engineer should also be copied on any changes that may affect electrical. The email subject line should reference the factory order number and state “'''Production Package Change'''”. For items that cannot be easily transmitted electronically, a hard copy will be given to the EDAA for distribution and an e-mail sent to the individuals listed above notifying them of the change. Any changes which affect submittal documents (drawings, engineering specifications, sequence of operation, etc.) must also be transmitted to the project sales engineer.

 

All changes must show a revision number and a revision date. Do not erase any previous revision dates, but add the new revision date to the document and leave all previous revision dates intact. Revisions will be numbered in sequence reflecting the total number of revisions to a document. The engineering file must also be updated with the revised data.
