Stop Contact Arcing – The Leading Cause of Compressor Single-Phasing

Single-phasing is the #1 killer of scroll compressors in roof top air conditioning units, and when they fail, the costs of a new compressor, a new contactor, and a few hours of maintenance time add up to a lot of money. Easy to install NOsparc arc suppressors help you avoid all of these costs. They remove 99.9% of the contact arc energy and extend the lifetime of the protected contactor by 10 times. No more pitted, scarred, or welded contact points that destroy your contactors. No more compressor single phasing due to contactor failure.

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:
