Are lower energy costs, improved food safety, product integrity, reduced shrinkage, and enhanced customer comfort important to your store?

Key Benefits of a Door Retrofit

Refrigeration makes up more than half of the energy used in a grocery store, and open multi-deck fixtures account for a large portion of the total. Therefore, through door retrofits, you have the opportunity to significantly lower the operating costs of your store. In fact, it is possible to reduce energy use over 50 percent on those open, multi-deck cases.


Other Important Benefits include:

Product integrity

With doors in place, merchandise is no longer subjected to the drastic temperature variations of open fixtures and has been proven to last longer. Customer perception of product integrity of products behind a glass door is higher, and they help ensure that the FDA’s mandated 41°F is consistently maintained.

Improved shopper experience

The aisles in your store are warmer and much more comfortable; customers dwell longer in front of the merchandisers and purchase more of your products!

Products are “showcased”

LED lighting (available on most new doors) presents the product in an enhanced, brighter, cleaner and more visible way; improved sales follow.

Avoided maintenance expense

LED lighting lasts 5 times longer and is up to 50% more energy efficient than traditional fluorescent tubes.

Equipment capacity for future use

Case BTU loads are reduced up to 70%, thus freeing up refrigeration system capacity for future expansion, or to help marginal systems get by today.

Utilities are on board

Many utility companies recognize these retrofits as “prescriptive” measures. In other words, you do the work, they give you a rebate. Cost to install doors can be significantly offset by utility incentives, improving your ROI.

Perception of a store remodel

Many shoppers comment that the new doors create the impression that the store has been remodeled. This positive perception is good for sales!
