Walk-In Series

As the industry evolved, several changes occurred. The HR-6 initiative passed and all glass door OEMs scampered to find cost effective alternatives, beer caves became more prevalent and the need for a simpler low amp anti-sweat controller emerged, and finally new more forceful directives were enacted to make the HR-6 initiative more measurable. With the 2012 changes, all OEMs were forced to measurably control heat once the humidity reached 55%. In response, we expanded the line to include a dozen Glass Sentry derivatives. The Glass Sentry Walk-in Series comprises 4 anti-sweat controllers in a smaller shell that will handle loads up to 10A. Now OEMs can match the controller to operate according to specific product line characteristics.

Another round of HR-6 initiatives comes into effect in 2017 with even more stringent requirements. Engineers are being forced to use all their resources to cut energy consumption wherever they can. Anti-sweat controls can make a big difference and the GSW-C can help with the new requirements. This is a closed loop unit making it the ultimate in maximum energy savings. It keeps condensation off the doors and frames when it needs to and it saves money when it’s impossible for fog to form. The unit’s rated to 10A giving it the needed flexibility to be used in supermarket, C-store, or drug store applications.

GSW-O

GSW-O

The GSW-O is an open loop unit with a generic algorithm designed for reach-in or walk-in applications. Based on humidity, it can be programmed generically from the factory or specifically to match the characteristics of the OEM product line. This 10A unit is a versatile and economical solution for engineers who have instituted other changes but still need additional savings to meet the new requirements.

GSW-OC

GSW-OC (1 OPEN/1 CLOSED)

The GSW-OC is a 2 output unit controlling both the glass door heaters as well as frame heaters with 1 closed loop humidity/frame sensor combination in addition to a second open loop algorithm. This gives engineers the option of controlling one heater circuit with the ultimate maximum savings and then using an open loop algorithm for a second less critical circuit.

GSW-OO

GSW-OO (2 OPEN LOOP)

The GSW-OO is a 2 output unit using 2 algorithms to control both the glass door heaters and the frame heaters. This unit allows OEMs to match the two outputs together. We provide the OEM with a software tool with table values that can be filled in with duty cycle numbers and %RH. Hard start times and cycle times can also be modified accordingly.
