HVACR

The Grässlin DTAV40 Series Auto Voltage Defrost Timer is applicable to air defrost (compressor shutdown) and electric or hot gas defrost systems where the defrost is terminated by the timer. If the coil is frost free, the timers can also be terminated by temperature or pressure switches before the programmed defrost termination time has been reached. The time termination functions as a fail-safe and terminates the defrost cycle if the temperature or pressure switch fails to do so.

New Product Highlights

IOS-DDR-W

The Intermatic® line of occupancy sensors are engineered and tested for long-lasting performance. In-Wall and Ceiling Mount sensors in both PIR (infrared) and dual (PIR/ultrasonic) technologies can monitor virtually any area within a building, providing solutions for any retrofit or new construction project. They utilize zero-crossing technology to suppress inrush current impact, supplying reliable ON/OFF sensing no matter the lighting technology.

ICUBE

The Intermatic® ICUBE™ Adaptive Defrost Module cuts defrost cycles--and utility bills--for the food service industry. Designed by Grässlin by Intermatic for commercial walk-in coolers and freezers, the smart-sensing technology behind the ICUBE™ continuously monitors evaporator coil temperatures and only allows defrosting when necessary at the next programmed timer interval.


Surge Protective Device Group Shot

The Intermatic® Surge Protective Device with Consumable Modules covers 100% of a home’s big investment equipment, from appliances and computers, to HVAC equipment and TVs. The Surge Protective Device uses replaceable Consumable Modules that allows homeowners to easily and safely replace a module when the built-in LED light indicates it has been compromised.
