Application

R-507, as a widely used low-temperature refrigerant today, is often used in refrigeration equipment such as cold storage, food refrigeration equipment, marine refrigeration equipment, industrial low-temperature refrigeration, commercial low-temperature refrigeration, refrigerated trucks, refrigerated condensing units, and supermarket display cabinets. R507 is also used as a long-term replacement for R502 and is mainly used in low temperature refrigeration systems.

 

Storage and transportation

The R-507 refrigerant cylinder is a pressurized container. It should be stored away from fire, heat sources, and direct sunlight. It is usually stored in a cool, dry and ventilated warehouse; it should be lightly loaded and unloaded during handling to prevent cylinders and valves, etc. Accessories are broken.

 

Refrigeration oil

The refrigerating oils usually used with R-507 refrigerant 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 The manufacturer's suggestion, or according to the specific conditions of the refrigeration compressor and refrigeration equipment, determine the use of the refrigerator lubricating oil of the same design and the requirements of the technician, that is, select the equivalent refrigerator oil.

 

Packing:

Non-recycled steel cylinder—11.3kg

 

Elimination timetable

R-507 belongs to the HFC type azeotropic refrigerant (completely does not contain CFC and HCFC that destroy the ozone layer), and has been recognized and recommended by most countries in the world as the mainstream low-temperature environmentally friendly refrigerant, and is widely used in the initial installation of new refrigeration equipment. and re-add during maintenance. It meets the standards of EPA, SNAP and UL of the US environmental protection organizations, and meets the A1 safety level category of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) (this is the highest level and is not harmful to human health).

 

Notice

R507, like R404A, is a long-term substitute for R502 and R22 refrigerants (HFC-like substances), but R507 can usually reach lower temperatures than R404A; R507 is suitable for all environments where R-502 can operate normally. Approved and used by most refrigeration equipment manufacturers. However, since R507 is different from R502 and R22 in terms of physical and chemical properties, theoretical cycle performance and compressor oil, it is still necessary to add or replace refrigerants for after-sales maintenance of refrigeration equipment initially installed with R502 and R22 refrigerants. Only R502 and R22 can be added, and usually R507 cannot be directly replaced with R502 and R22 (that is to say, exchange-type replacement is usually not possible).
