Application

commercial refrigeration equipment;

Newly designed products and existing R-502 equipment.

Advantage

Very close to R-502: Works over the entire R-502 operating range.

Use OEM-recommended POE lubricants for best reliability


The main purpose
As a widely used medium and low temperature refrigerant today, R404A is often used in cold storage, food refrigeration equipment, marine refrigeration equipment, industrial low temperature refrigeration, commercial low temperature refrigeration, transportation refrigeration equipment (refrigerated vehicles, etc.), refrigeration condensing units, supermarket display cabinets and other refrigeration equipment.

Refrigerant R404A is the most common industry standard refrigerant to replace Freon R22 and R502 on new refrigeration equipment (usually low temperature refrigeration systems), R404A is the closest to the operation of R-502, it is suitable for all R-502 can work normally. Environment, R404A is recognized and used by most refrigeration equipment manufacturers in the world. However, because R404A and R502 and R22 have different physical and chemical properties, theoretical cycle performance and compressor oil, etc., for after-sales maintenance of refrigeration equipment initially installed with R502 and R22 refrigerants, if it is necessary to add or replace refrigerants, still Only R502 and R22 can be added, and R502 and R22 cannot be directly replaced by R404A (that is to say, exchange-type replacement is usually not possible).

 

Precautions

Refrigerant R404A steel cylinders are pressurized containers, which should be kept away from fire, heat sources, and direct sunlight during storage. They are usually stored in a cool, dry and ventilated warehouse; they should be lightly loaded and unloaded during handling to prevent damage to cylinders and valves and other accessories .

R404A supporting the use of refrigeration oil

The refrigerating oil usually used with refrigerant R404A are: ICEMATIC SW32, SW220, EMKARATE RL32H, RL170H, etc.; which refrigerating oil is finally used in different equipment and different application places, should comply with the refrigeration compressor and refrigeration (air conditioning) equipment manufacturers It is recommended, or determined according to the specific conditions of the refrigeration compressor and refrigeration equipment, to use the refrigeration oil of the same design and the requirements of the technician, that is, to select the equivalent refrigeration oil.
