1. We have our own labs to guarantee the gas purity 99.93%

2. REACH certificate for Europe is available if necessary

3.We have our own corporated company for production of cylinders.

4. The cylinders have CE,KGS and DOT certificate, small cans have DOT certificate

5. We have R32,R152,R22,R134A,R410A,R407C,R404A,R290,R600A etc…

Why R290 Refrigerant is Good?

High-purity R290 is used as a temperature-sensing working fluid; premium and first-grade R290 can be used as a refrigerant to replace R22, R502, compatible with the original system and lubricating oil, and used for central air conditioning, heat pump air conditioning, household air conditioning and other small refrigeration equipment , Can also be used for metal oxygen cutting gas.

    R290: A potential refrigerant substitute

    The refrigerant R290, or propane, is a natural hydrocarbon refrigerant that can be obtained directly from liquefied petroleum gas. Compared with Freon, a synthetic refrigerant, the natural working fluid R290 does not contain chlorine atoms in its molecules, so the ODP value is zero, which does not have a destructive effect on the ozone layer. In addition, compared with HFC substances that also have no destructive effect on the ozone layer, the GWP value of R290 is close to 0, which has no effect on the greenhouse effect.

Package and Shipment

Buy from Frioflor company for various kinds of refrigerant gas.

After the comparison of thermal cycle calculations, it is believed that the various thermodynamic properties of R290 and R134a are relatively close. When R290 is used instead of R134a, R290 exhibits superior performance and efficiency than R134a, which can achieve low-temperature cooling and rapid cooling, and improve the overall performance of the system. And through matching examples, it is verified that R290 replacing R134a system not only reduces the process and operation difficulty, but also reduces the product cost.
