use and performance

My factory production XH-7 is develops adapts the HFC-134a drying agent:

1. Chemistry compatibility

2. High infiltration capacity

3. High pellet anti- intensity

4. Dry anti- abrasion ability

5. The hydration anti- rubs the ability

The empirical datum indicated uses in CFC-12 the automobile air-conditioning system 4A-XH-5 drying agent and HFC-13A has the chemical reaction,therefore needs one kind of new product.This kind of new drying agent had to maintain and the before product equally good performance is extremely difficult,but my factory production XH-7 was in fact better than in the hydration anti- abrasion ability aspect the before product.

Along with the XH-7 commercialization,first time establishes the quality guarantee test method and the strict hydration abrasion target in the refrigeration industry.Although XH-7 is the development uses in the automobile air conditioning,but its performance caused it in the static system was still an outstanding product.Does not have "the outgassing" with 4A-XH-6 same XH-7,therefore the system pulls out the vacuum time to be shortest.

My factory production XH-7 is recommended with uses CFC-12 and in the HFC-134A original installation equipment,also may recommend uses in HFC-134A replacing in CFC-12.XH-7 cannot use in HCFC-22 and the HFC-152A mix refrigerant original installation equipment or the replace.
