Moisture is a problem for any system and a concern of all technicians. If it is not removed, acids as well as corrosion and other problems can trouble the system and the compressor. Nu-Calgon has developed a revolutionary product called A/C EasyDry. This product is a quick and simple way to eliminate moisture in a system. It can also be used to prevent moisture in a system that may not already have a problem. A/C EasyDry contains a dehydrating agent that converts system moisture into a natural organic material that is compatible with and mixes with the lubricant. It is great for preventing acid formation which is caused by moisture in a system and works with all refrigerants (accept ammonia). Each can treat up to a 5 ton system and is easily installed with the reusable piercing valve and hose.
