Arctic Air for R22 Systems and Proseal XL4, Prodry XL4, Brass Gauge

This product is a combination of two Enviro-Safe products mixed into one to promote maximum cooling performance. It will remove moisture from the AC system, as most people know that moisture leads to corrosion and leaks, which no one wants in their AC system. This product also will reduce friction in the system and provide colder air duct temperatures in most cases.

The Enviro-Safe Proseal XL4 is an aerosol that forms a hard seal on metal, Schrader valves, o-rings, gaskets, AC condensers, evaporators, line sets, and solder joints. It is designed to repair minor leaks in home, heat pump, large auto, and industrial applications. One can will normally repair a leak in systems up to 5 tons. If the AC system will not hold a vacuum, the Enviro-Safe Prodry XL4 should be used, as it will eliminate moisture in the system, which can cause sulfuric acid to form and corrode the system.

For larger units over 5 tons, the Enviro-Safe Proseal XL4 Direct Inject is recommended. Even though Proseal XL4 can form a seal on the Schrader valve, when you hook up to it, the seal will release and allow you to use the Schrader if necessary. If there is still Proseal XL4 in the system, it will reseal the Schrader.

The Enviro-Safe ProDry contains a dehydrating agent that converts system moisture into oil. It is recommended to use ProDry XL4 before the use of Enviro-Safe ProSeal XL4 to ensure all moisture has been removed from the air conditioning system. ProDry XL4 should be used on any home AC system that has leaked below 15 psi (running or not running) or if the system has ever leaked below 15 psi in the past.

This product is an AC booster for 22 systems, providing drying agent, colder air, and longer life for the AC system. It can be used as a system-protector against system failure and protects against leaks formed by corrosion.

The product is made in the USA by a family-owned company for 27 years, specializing in Arctic Air for R22 refrigerant.
