Oxygases Brand Refrigerant Gases

Oxygases, Ras Al Khaimah, UAE – is an importer and supplier of refrigerant gases under the brand “OxyGases” to HVACR industry, Mobile Air Conditioning, Refrigeration, and Air Conditioning market. They offer a wide range of products like fluorocarbon refrigerants including CFCs, HFCs, HCFCs, & HFO. Also supplies environmentally friendly natural refrigerants.

“Oxygases” brand refrigerants are well known in the HVAC market for their better performance, lower global warming potential, and reduced environmental impact.

Generations of Refrigerants

Since innovation during the 1830s, Ether, CO₂, Ammonia, and Sulphur Dioxide were part of the “First Generation” of refrigerants.

“Second Generation” during the 1930s saw the introduction of H₂O, NH₃, Hydrocarbons, etc., followed by CFC and HCFC.

“Third Generation” introduced in the 1950s with improved versions of HFC, HCFC, CO₂, H₂O, and NH₃. Soon after, in 1987, the “Montreal Protocol” to safeguard the ozone layer was implemented.

“Kyoto Protocol” was an international treaty that extended the 1992 United Nations Framework Convention on Climate Change, committing state parties to reduce greenhouse gas emissions, based on scientific consensus that global warming is occurring and that human-made CO₂ emissions are driving it.

“Fourth Generation”, introduced in 2010, observed a massive change in the refrigeration industry with the introduction of HFOs along with improved HCs, HFCs, CO₂, and Ammonia.

Extensive research continues in this domain, with the goal of achieving lower ozone depletion.

CFCs (Chloro Fluoro Carbon)

CFCs refer to the chemical composition of the refrigerant. Chloro Fluoro Carbon indicates the content as Chlorine, Fluorine, and Carbon. Any blend of refrigerant with CFC as content is considered a CFC refrigerant.

Examples: R11 | R12 | R500 | R502

HFCs (Hydro Fluoro Carbon)

HFCs are the chemical composition of the refrigerant, namely Hydro Fluoro Carbon. It consists of Hydrogen, Fluorine, and Carbon. Any blend that contains HFC is addressed as HFCs.

Examples: R23 | R32 | R134a | R404A | R407a | R407c | R407f | R410a | R417c | R422B | R422D | R507 | R508B

HCFCs (Hydro Chloro Fluoro Carbon)

Known as Hydro Chloro Fluoro Carbon, it contains Hydrogen, Chlorine, Fluorine, and Carbon. A blend that contains HFCs and HCFCs is considered an HCFC refrigerant.

Examples: R22 | R123 | R124 | R401A | R401B | R402A | R402B | R403B | R408A | R409A

HFOs (Hydro Fluoro Olefin)

HFO refers to the chemical composition of Hydro Fluoro Olefin. It contains Hydrogen, Fluorine, and Carbon, with at least one unsaturated double bond between two carbons (olefin structure). A blend of HFO with another type of refrigerant is typically combined with a slash (Example: HFC / HFO).

Examples: R1233zd | R1234ze | R1234yf | R448A | R513A | R449A | R450A | R452A

Natural Refrigerants

Hydrocarbons are naturally occurring chemicals made only from Hydrogen and Carbon. A blend of hydrocarbon with any other type of refrigerant would be considered the other type of refrigerant (CFC, HFC, HCFC, or HFO).

Examples: R717 (Ammonia) | R744 (CO₂) | R1270 (Propylene) | R290 (Propane) | R600a (Isobutane)
