Saving money in the store

GE Plastics has developed a polycarbonate film that can prevent condensation on the doors of refrigerated and frozen food glass door cases without the need to heat the glass.

The so-called Lexan “Constant Clear” film, features a proprietary anti-fog coating that adheres to glass doors to help prevent formation of condensation when the cases are opened by shoppers.

By avoiding the need to heat glass doors, reducing the frequency of door openings to view products, lowering compressor loads required to compensate for heated doors - and based on the US national average energy cost of $0.0942/KW-hr (according to www.eia.doe.gov) – GE Plastics says that the new film can save up to $90 per door, per year on ice cream and low temperature doors and $30 per door, per year on medium temperature doors.

A typical store with 130 doors consisting of 60 percent low-temperature doors, 20 percent medium-temperature doors, and 20 percent ice cream doors can expect to save approximately $10,000 a year if Lexan Constant Clear film is applied and door heating is turned off.
