The air-conditioning system and filling procedures without changing ,same as the original filling procedures, but it is recommended to use digital scales to ensure the accuracy of the amount of filling.
7) Widely used
Suitable for home air conditioners, central air conditioning, refrigerated trucks, heat pumps and other refrigeration systems
8)High adaptability
Unique adaptability to the hot climate.
9)Completely reaching the international standard
Fully compliance with international environmental requirements, ODP is equal to 0, GDP100 less than 3.
HCR22a is a new natural refrigeant Ze China company developed mainly used in dindoor air-conditioning fields,which does not destory the ozone layer and the greenhouse effect is almost zero,this product can replace R22 refrigerant directly without the modification of the equipment.the constumption of HC-R22a is only 1/2 of the original refrigerant and widely used in refrigeration field,therefore, HC-R22a;HC-R134a is regarded as excellent long-term replacement scheme of automotive airconditioning in the future And home air conditioning
