HVACR

Power disturbances damage air conditioner compressors without warning. Let the Compressor Defender™ take the hit so air conditioners are never interrupted. The all-in-one Compressor Defender device protects compressors and circuit boards in residential and light commercial applications from brownouts, surges, and short cycles. The protective device can be installed inside a condensing unit or externally on an AC disconnect. It is also compliant with the AHRI standard 110-1012.

Where to Buy

Combine the Compressor Defender™ with the surge protection of the Intermatic AG3000 for a Power Protection Duo.

Compressor Defender™

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.
