 “Losing a $3,000 compressor because of a failed $50 contactor is ridiculous, and should never happen.”

Protect Your Refrigeration Compressors From Single Phasing!

Protecting $3,500 refrigeration compressors is a primary goal for refrigeration technicians at grocery stores and convenience stores. A big part of that effort hinges on replacing worn or failed contactors, which often lead to compressor single phasing and loss of the motor.

But there’s a better way to protect your motors and your refrigerated food inventory: NOsparc arc suppressors. When wired in parallel across each pole of your contractor, the GCLAC3F480 NOsparc arc suppressor removes 99.9% of the arcing energy from your contact points and extends the lifetime of your power contactor by at least 10 times. No more pitted or scarred contact points. No more contacts that fail open and quickly lead to compressor single phasing.

More than $5 billion is spent on contactors and relays each year, and the majority of the purchases are to replace contactors that have failed due to contact arcing! With NOsparc arc suppressors protecting your contactors, your annual costs for replacement contactors could drop by 75% or more, and you’ll get the normal full lifetime of performance from your refrigeration compressors.

NOsparc products are patented and UL Certified, and they are simple to purchase and easy to install. Here’s how you can get started in protecting your store from the high costs of compressor single-phasing:

  1. Watch our GGX installation video
  2. If your compressor has a Locked Rotor Amperage of 235 amps or less and an operating voltage of 480 Vac or less, the new, universal GCLAC3F480 is the ideal arc suppressor for the job.
  3. Order one GCLAC3F480 NOsparc arc suppressor for each compressor motor you wish to protect (Buy Now)
