Natural refrigerants

In the future, natural refrigerants will be the only option. Making the change right now is one of the most important things you can do for our climate. Read here to learn more about natural refrigerants and what the F-gas regulation means.

Does not add to the greenhouse effect

Synthetic refrigerants have a major impact on the greenhouse effect. By replacing them with natural refrigerants, you’re doing the world a great service.

Under the F-gas regulation, the EU will phase out refrigerants with high environmental impact. In the future, natural refrigerants will be the only remaining option.

Many have already discovered the benefits of natural refrigerants. Consumers want to see greener options, and by making the change right now, your company will be a trailblazer.

We need to act now

The GWP (Global Warming Potential) value is usually measured over 100 years. The Global Warming Potential describes the relative potency, molecule for molecule, of a greenhouse gas, taking account of how long it remains active in the atmosphere.
But if we are to become climate neutral by 2050, we must measure over 20 years. Unfortunately, we do not have 100 years on us, and the transition to natural refrigerants now needs to occur.
”Hydrofluorocarbons (HFCs) and new generation refrigerants such as hydrofluoroolefins (HFOs) and HFO blends are marketed as “climate friendly” because they are not ozonedepleting and have seemingly low GWPs. However, when assessing the real lifetime of these refrigerants, their negative impact on health, safety, and the environment raises concern”, states ATMOsphere, the global independent market accelerator with a mission to clean up cooling.

The table shows a significant difference between measurement over 100 years and measurement over 20 years.

Here is a complete version of the list of genuine GWPs where you can read more about what it means.


Refrigerant GWP 100 years Real GWP 20 years
HFC/HFO 570-4200 1660-6600
CO2 1 1
Propane <1 <1
NH3 0 0

Is propane safe?

Propane has long had a reputation as a fire hazard. But with safe handling, our extensive experience and the modern units we use today, it’s a safe alternative.

Are they difficult to install?

Enrad modules are designed to fit new and old plants alike. Installation is therefore quick and easy with simple component replacement.

Do I have to use natural refrigerants?

The EU is currently phasing out F-gases completely as they’ve been shown to have a major impact on the climate. In a few years, natural refrigerants will be the only option.

Are they expensive?

While natural refrigerants cost a little more than F-gases, the units are energy efficient and built for long life, so things even out in the end.

What natural refrigerants are there?

Natural refrigerants include propane, CO2 and ammonia, where propane has the lowest true GWP value. We use propane and propylene to ensure the best properties in the -8 to +60 temperature range.

What is the F-gas regulation?

It is an EU regulation that governs various greenhouse gases. It will have a major impact on our industry as F-gases are widely used in refrigeration and heat pump units.

“As the total amount of CO2 equivalents in sold F-gases is reduced, an increasing number of refrigerants with high GWP values relative to the annual average will be affected. Initially, there will be price increases followed in all likelihood by shortages.”

Are you ready to cross the threshold to a climate-neutral society?

Then we’d love to hear from you! It’s natural to have a few questions when replacing something you’re used to with something new. But we’re here to answer all your questions, whether they’re about our products or natural refrigerants in general.
