R404a Refrigerant Gas – WESTRON

Westron 404A is a Non-Ozone Depleting, Non-Toxic, Non-Flammable Refrigerant developed for a variety of Medium and Low-Temperature Refrigeration applications. The type of Westron R-404 is HFC – Azeotropic blends of three refrigerants namely R 143a ( 52 % ) R125 ( 44%) and R 134a ( 4 %). Westron 404A blends are suitable for Refrigeration applications like Food Display Cases, Deep Freezers, Storage Cases, Cold storage Rooms, Ice machines, Food processing units, Industrial Refrigeration. Also in Transport Refrigeration like Refrigerated Trucks, Refrigerated Containers, Vessels and Trawler Cold Rooms. Westron R-404a is an HFC Azeotropic blend and for this reason, it is suggested to use the Liquid form of Refrigerant for charging the system to avoid damage.

LUBRICATION
Westron 404a requires a POLYESTER (POE) Lubricant to ensure complete miscibility between oil and refrigerant. Miscibility is important for oil return to the compressor especially in a large system with long runs of piping.POE Oil absorbs moisture quickly when it is exposed to the atmosphere. Any way please handle the equipment very carefully and avoid prolonged exposure to air.
