1. R134a (tetrafluoroethane)

Refrigerant R134a is currently one of the main internationally recognized alternative refrigerants for R12. It is commonly used in automotive air conditioners, commercial and industrial refrigeration systems, and as a blowing agent for the production of hard plastic insulation materials. Refrigerants, such as R404A and R407C.

Main use: mainly replace R12 as a refrigerant, used in a large number of car air conditioners and refrigerators.


2, R410A

Physical and chemical properties: At normal temperature and pressure, R410A is a non-chlorine-containing fluoroalkane azeotropic mixed refrigerant, colorless gas, which is compressed liquefied gas stored in a steel cylinder. Its ODP is 0, so R410A is an environmentally friendly refrigerant that does not destroy the atmospheric ozone layer.

Main application: R410A is mainly used to replace R22 and R502. It has the characteristics of clean, low toxicity, non-combustible, and good cooling effect. It is widely used in household air conditioners, small commercial air conditioners, and household central air conditioners. Packed in steel cylinders, the net weight is 11.3kg, 500kg, 1000kg.


3, R407C

R407C is a non-azeotropic fluoroalkane non-azeotropic mixed refrigerant at room temperature and pressure, a colorless gas, which is compressed liquefied gas stored in a steel cylinder. Its ODP is 0, so R407C is an environmentally friendly refrigerant that does not destroy the atmospheric ozone layer.

Main use: R407C is mainly used to replace R22. It has the characteristics of clean, low toxicity, non-combustible, and good cooling effect. It is widely used in household air conditioners and small and medium-sized central air conditioners. Packed in steel cylinders, the net weight is 11.3kg, 500kg, 1000kg.


4. R417A

R417A is a non-azeotropic fluoroalkane non-azeotropic mixed refrigerant at room temperature and pressure, a colorless gas, which is compressed liquefied gas stored in a steel cylinder. Its ODP is 0, so R417A is an environmentally friendly refrigerant that does not destroy the atmospheric ozone layer.

Main use: R417A is mainly used to replace R22. It has the characteristics of clean, low toxicity, non-combustible, and good cooling effect. It is used for heat pump (OEM replacement of R22 at initial installation) and air conditioner (after-sale replacement of R22). Packed in steel cylinders, the net weight is 11.3kg, 400kg and 1000kg.


5. R404A

R404A must not be a non-azeotropic mixed refrigerant that does not contain chlorine. It is a colorless gas at room temperature and pressure. It is a compressed liquefied gas stored in a steel cylinder. Its ODP is 0, so R404A is an environmentally friendly refrigerant that does not destroy the atmospheric ozone layer.

Main use: R404A is mainly used to replace R22 and R502, with the characteristics of clean, low toxicity, non-combustible, and good cooling effect, and is widely used in low-temperature freezing systems. Packed in steel cylinders, the net weight is 10.9kg and 1000kg.
