Frequently Asked Questions (FAQs)

Sometimes you just need a little help. Please check this section if you have questions.

Technical / Engineering/ Application

Q. How do I choose the correct unit based on my BTUH capacities/ How do I determine BTUH capacity for your products so I can request a quote?
A. Our proprietary Kramer box load program (Kramerbox) will enable you to perform a full box-load analysis to determine BTUH capacities based on your unique criteria. You can select equipment from the catalog or contact your local Kramer Representative for an equipment selection and price quote.

Q. Do you have wiring diagrams, installation and operating information available? What about for older models?
A. Our Installation and Operations Manuals (IOMs) are available online and contain all the information needed to install, run and maintain our units. If you have an older model and can’t find the IOM online, use the Contact Form and provide us with the model and serial numbers and we’ll check our library and reply with the information.

Q. How can I determine the manufacture date of my unit?
A. We have an online Kramer Serial Number Research Database you can use for researching parts and original job information for KRAMER equipment produced between 3-14-1974 to 1-31-90 or having Serial Numbers between E44400 to F79063. If your equipment is newer than 1990, then use the online HTPG Serial Numbers Chart to determine the facility, month and date of manufacture. You will need the full serial number of the unit. If the serial number of your unit has less than 18 digits, you’ll need to contact our Customer Service Department at phone: 800-288-9488 or 256-259-7400 and they can research it for you.

Q. How do I check/set/change the settings on my APEX unit controller?
A. HTPG’s online APEX Installation and Operations Manual has instructions for this starting on page 9 and going through page 12. Click the title above to download the manual.

Q. Why does my freezer have icicles forming on the ceiling around the evaporator?
A. This problem is most often caused by excessive infiltration of moisture-laden air. Frequent door openings, air leaks, and heavy product loads can be primary causes. Our website has two documents that will be useful in correcting the problem: Icing in Walk-in Freezers and Systems Installation and Operations Manual.

Q. How can I replace the electric defrost heaters in my evaporator?
A. We have a bulletin that covers replacement of defrost heaters on our website: Defrost Heater Replacement

Q. How can I determine the correct TXV for my evaporator if changing refrigerants?
A. We have a Sporlan Chart on our website for the preferred Sporlan Balanced Port TXV selections.

Q. What refrigerants do Kramer products currently support?
A. Walk-in/warehouse style unit coolers as well as all air cooled condensers are available circuited for use with most any currently available HFC, HCFC (or even CFC) refrigerants. Most condensing units are available for use with currently available HFC’s, but can no longer be nameplated for use with any HCFC’s or CFC’s.

Q. What if my customer’s application requires a custom built unit or special option which is not listed in any product literature?
A. These requests can be submitted for review by our application engineering group by using our online Custom Quotations link from our Pricing page.

Q. What types of protective coil coatings are available for units which are installed in potentially corrosive environments?
A. Depending upon the product type, Kramer currently offers three basic types of coil corrosion protection:

  • Polyester coated (pre-painted) fin stock.
  • Russ-Proof (an aerosol applied epoxy paint coating).
  • ElectroFin (a flexible, cationic epoxy polymer applied using an electro-coat process).

Q. Does Kramer currently offer any of their products for use in explosion proof applications?
A. Although our products are sometimes modified in the field by other companies to conform to hazardous environments we do not offer any of our products in an explosion proof configuration as originally produced in our factory.

Q. What is the standard control voltage for Kramer condensing units?
A. All condensing units are wired from the factory with 208/230 volt control circuit power. For 460 or 575 volt units this voltage is typically supplied from a factory mounted, step-down control circuit transformer. As an option, we offer 120 volt control power for most unit models for an additional cost.

Q. Where can I get submittal data sheets for the equipment I wish to order?
A. Submittal data sheets for many of our products can be found on our website on our Submittals page. If the unit model/ series which you require submittal data for isn’t listed, please contact your local Kramer Sales Representative or use our Contact Form.
