Recommended information

R744 R290 R600a Natural refrigerant gas Eco Freeze

R744 R290 R600a Natural refrigerant gas Eco Freeze

Environmentally friendly natural refrigerant gases for a society moving towards the elimination of fluorocarbons.

In response to today's society moving away from fluorocarbons, Iwatani has been selling natural refrigerant gases for many years under the Eco Freeze series. The Eco Freeze lineup includes R744 (carbon dioxide), R290 (propane), and R600a (isobutane), all supplied in high-quality standards with minimal impurities to ensure safe use for our customers. We offer various supply forms tailored to customer needs, ranging from large containers for production purposes to small containers for after-sales and research applications. If you are considering compliance with PFAS regulations, F-gas regulations, or switching from fluorocarbon refrigerants to natural refrigerants, please consider the "Eco Freeze series," which balances excellent quality with essential elements necessary for refrigerants.
