The more stringent 2017 energy directives are affecting the manufacturers of
merchandisers. Engineers are re-thinking their designs and incorporating anti-sweat
controls. Because merchandisers are so cost sensitive, the controls need to be
economical, save energy, meet the directives, and work in an array of environments.
The Glass Sentry Merchandiser Series is comprised of 4 anti-sweat
controllers that will handle the 3 Amp loads of a typical merchandiser. Now OEMs
can install the controller before the units leave the factory and make sure that
the controllers operate according to their specific product line characteristics.
GSM-C
The GSM-C is an economical single output
unit designed to control smaller 3A loads typically found in
freezer merchandisers. The unit incorporates a discrete dew
point sensor and separate temp sensor to determine optimal
savings. As the dew point is approached, the unit turns on
power to the heater circuit thereby preventing condensation.
When physics dictate that it’s impossible for condensation to
form, power to the heater circuit is shut off thereby saving
energy and lowering electrical bills.

GSM-O
The GSM-O is an open loop unit using an algorithm to control
smaller 3A merchandiser loads. Humidity is the primary factor
affecting the algorithm. While not as efficient as the closed
loop system, the GSM-O unit uses a single sensor which saves
wiring labor and still saves a good deal of energy. It’s a good
economical solution for a number of applications.

GSM-OC (1 OPEN/1 CLOSED)
The GSM-OC is a dual output unit designed to
control both the glass door heaters as well as frame heaters in
merchandisers. This unit allows 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.

GSM-OO (2 OPEN LOOP)
The GSM-OO is a dual output unit designed to control both the
glass door heaters as well as frame heaters in merchandisers.
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.
