R290 - propane

R290 is pure hydrocarbon (HC) with a low GWP coefficient, and a purity of at least 99.5% or 99.9%, used in residential refrigeration and small commercial cooling devices, as well as mobile air-conditioning units.

R290 is a flammable refrigerant.
It has been used in household refrigerators and portable air-conditioners since the early 1990s.
In addition, R290 is a component of several blends available on the market.
From an ecological standpoint, R290 is a gas with a low GWP (3) and a zero ODP.

R600a is a hydrocarbon (HC) with a low GWP coefficient, and a purity of at least 99.5% or 99.9%, used in residential cooling systems and small commercial cooling devices.

R600a is a flammable refrigerant.
Owing to its physical and chemical properties and as the most appropriate agent for medium/high-temperature applications, it has been used in fridges since the early 1990s.
In addition, R600a is a component of several blends available on the market.
From an ecological standpoint, R600a is a gas with a low GWP (3) and a zero ODP.

R600a - isobutane

R1234ze

R1234ze is pure hydrofluoroolefin (HFO) with a low GWP coefficient. It is developed pursuant to the provisions of the regulation (EC) No. 517 aimed at reducing the GWP of the HFC gas refrigerant. It has numerous air-conditioning and refrigeration applications. R1234ze was developed as a substitute for R134a, but has also been used for other sectors/applications over the years. In addition, R1234ze is an ingredient of several commercial available blends with a low GWP. From an ecological standpoint, R1234ze is a gas with a very low GWP (7) and a zero ODP.
