All you need to know about Isobutane R600A

In this article, you will learn all you need to know about isobutane R600A. We go through its advantages and disadvantages as a refrigerant, and suitable applications. Isobutane R600A is a hydrocarbon-based refrigerant commonly used in cooling and freezing applications for households and for commercial cooling.

It has become a popular choice of refrigerant because of its high thermal conductivity. Isobutane R600A belongs to the same HC group as propane R290 and propylene R1270, and it often replaces the R12 and R134a refrigerants.

Isobutane R600A – an environmentally friendly refrigerant

As you probably know, F gases are harmful to the environment.

The EU is therefore phasing out synthetic refrigerants, due to their high GWP values and PFAS emissions. Due to the updated F-gas regulation and proposal to ban PFAS as a property owner, consultant or installer, you will soon be required to switch to natural refrigerants such as isobutane.

Isobutane R600A has a low global warming potential (GWP 3). Isobutane R600A is also a light and natural gas that does not release harmful substances such as PFAS or TFA. This makes the R600A a good choice of refrigerant, now and in the future.

Isobutane R600A and energy efficiency[

Isobutane R600A has high thermal conductivity, which provides efficient cooling and faster heat absorption. This means that with less isobutane you perform the same process that many other refrigerants do – an energy-efficient solution that reduces both energy consumption and operating costs.


Disadvantages with isobutane R600A

It has an A2 rating on the fire classification scale, which means it is highly combustible. Extra safety precautions are therefore required to minimise the risk of fire or explosion. In light of current regulations and standards, this is not a problem and all the plants that use flammable refrigerants have the necessary safety precautions in place.

At Enrad, we have extensive experience of using isobutane.

Grocery store refrigeration

When Francks Kylindustri received an inquiry from the grocery store ICA in Södertälje about a sustainable, natural refrigerant solution for their chillers, they contacted Enrad.
