- PRODUCT DESCRIPTION AND APPLICATIONMaxron 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 Maxron R-404 is HFC – Azeotropic blends of three refrigerants namely R 143a (52%), R 125 (44%) & R 134a (4 %). Maxron 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. Maxron 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.
- LUBRICATIONMaxron 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 large systems 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.
