Glass Sentry
The Glass Sentry is now the crown jewel of our
anti-sweat product line. The Glass Sentry is UL
listed economical model designed
specifically for retrofit applications. The unit has a discrete
dew point sensor and separate temp sensor. By handling up to 30
amp loads, a single Glass Sentry can control the multiple door
set-ups of a typical C-store. Once the heater circuit is turned
on, it stays on for a minimum of 5 minutes, assuring that the
surface temperature of the glass is properly elevated without
wasting energy. An adjustment on the end of the unit is set for
optimum operation for all conditions, but can be changed for
even better energy-savings depending on the conditions.
Pig-tail leads and flexible conduit provided with the Glass
Sentry allow for easy retrofit installation without any
additional wiring which translates into minimum up-front costs
and head-aches. The Glass Sentry can pay for itself within
months of installation and it is now one of the most popular
energy saving alternatives for the C-store industry.

Glass Sentry II
As the industry became more accepting of the
anti-sweat philosophy, customized requests became more and more
frequent. We developed the Glass Sentry II to utilize a single
humidity sensor and preset logic tables. Now customizers can
tell us when they want the unit to operate, how long they want
it to energize, and match it to the operational functionality
of their particular boxes. The Glass Sentry II can still
control 30A loads. It’s mounted on top or inside of the box
making it versatile enough for retrofit or new installations.
The Glass Sentry II is ordered with freezer logic or with
cooler logic. If you have specific ideas about how you’d like
an anti-sweat controller to work, then the Glass Sentry II is a
good alternative.

Glass Sentry LP
When the HR-6 initiative was passed and
incorporated in January 2009, it required all cooler
manufacturers to either use more expensive energy efficient
glass doors or to install anti-sweat controllers into their
units. We redesigned the Glass Sentry into a low profile,
potted option that could be mounted in the mullion. Tens of
thousands of these units have been used and are now a standard
component on a number of cooler systems. The Glass Sentry LP
utilizes a discrete dew point sensor and one smaller separate
temp sensor. It remains a popular model with cooler OEMs.

Glass Sentry Modbus
Many of the larger grocery and C-store
chains utilize more sophisticated building automation controls
(BACs). Process specific controls for lighting, security,
refrigeration, pumping applications, etc. link with the BAC
computers to collect, analyze, and present data in real time to
corporate executives. We chose the Modbus communication format,
the most widely accepted format, and incorporated it into our
Glass Sentry line so that we could communicate with BAC
controls and open a marketing avenue into these larger
industries. Parameters such as relative humidity, store
humidity, dew point, frame temperatures, percent heater run
time, hour watts saved, as well as alarm conditions can be
viewed on a unit by unit basis. Perfect for the Corporate
Energy Manager to evaluate site efficiencies and analyze
systems from the convenience of their desk.

Glass Sentry II Modbus
The Glass Sentry II Modbus combines preset logic algorithms
with the Modbus communications protocol thereby allowing larger
grocery and C-store chains to utilize more sophisticated
building automation controls (BACs). Process specific controls
for lighting, security, refrigeration, pumping applications,
etc. link with the BAC computers to collect, analyze, and
present data in real time to corporate executives. Parameters
such as relative humidity, store humidity, dew point, frame
temperatures, percent heater run time, hour watts saved, as
well as alarm conditions can be viewed on a unit by unit basis.
The Glass Sentry II Modbus is another option for the Corporate
Energy Manager to evaluate site efficiencies and analyze
systems from the convenience of their desk.
