The R32 refrigerant is a gas that complies with the European directives on the reduction of the greenhouse effect, presenting a GWP (Global Warming Potential) lower than the R410A gas and not damaging the ozone layer.

The Global Warming Potential (GWP) is the index that represents the impact that a substance can have on the global greenhouse effect, indicative of the corresponding equivalent tons of CO2. It is a relative index that compares the impact of 1 kg of refrigerant with 1 kg of CO2 over 100 years. Another often used parameter is the Ozone Depletion Potential (ODP), or the Ozone Reduction Potential. It represents the index of the harmful capacity of a refrigerant gas towards the state of ozone present in the stratosphere. R32 gas, like R410A gas, does not damage the ozone state in any way if it is released into the atmosphere and therefore has an ODP value of 0.

But is R32 gas also safe?

Belonging to the category of low flammability refrigerants (class 2L ISO 817) it is safe for 3 simple reasons:

- the flammability range is very limited;
- it does not turn on easily (a switch of common household appliances is not enough to turn it on);
- has low toxicity.

By applying the appropriate procedures during installation, maintenance and operation, the units that use R32 gas do not present risks and dangers. The advantages deriving from the use of this refrigerant are essentially five:

- high energy efficiency;
- reduction of the amount of refrigerant gas used;
- reduced environmental impact;
- ease of refilling and recoverability as pure gas;
- low toxicity and flammability.
