Price Chopper Anti-fog Freezer Film 

Lexan* Constant Clear film allows supermarket chain to turn off glass door heaters and reduce the load on compressors

With razor-thin profit margins, supermarkets must be vigilant in controlling overhead costs such as electricity. Price Chopper, a privately held supermarket chain headquartered in Schenectady, NY, is particularly focused on cost control due to its brand message of low prices for shoppers. When Price Chopper was approached by SABIC Innovative Plastics regarding a new, energy-efficient way to ensure fog-free doors on freezer and refrigerated cases, the company decided to conduct a trial. The results of a two-year test of Lexan Constant Clear anti-fog freezer film were so impressive that Price Chopper has installed the film in 10 stores with plans for more.

SABIC helps Farm-Fresh shoppers see clearly inside frozen food glass door cases, while reducing energy costs

"We wanted to find a better anti-fog solution for existing stores and also to speed up new construction." said Perry (John Perry, Director of Energy and Maintenance at Farm Fresh, USA).

 The Solution: SABIC's Anti-Fog Freezer Film to Replace Door Heaters

 The Benefits: Energy Reduction and Improved Clarity for Shoppers

"We verified the anti-sweat heater amperage dropped by about 50% for the doors using SABIC's film - from 5.2 amps to 2.4 for a four door frozen food glass door case, when the glass door portion is disconnected, " Perry reported. "But that is just one aspect of the energy savings. We also expect of between 10 and 30% in energy usage for our compressors, since they no longer have to work so hard to remove the added heat from the cases."

"We have not seen any degradation of the film during our 18-month test, " Perry said. "This is a simple. passive system that can be installed quickly and doesn't need special care or periodic reapplication - and, requires less energy to operate. We plan to continue rolling it out to our other locations."
