Why this matters

Most refrigeration runs on chemicals that warm the planet, or quietly poison it.

HFCs warm the atmosphere up to 14,000× more than CO₂. Their HFO replacements break down into TFA, a forever chemical now detectable in rain, ice, and human blood.

The answer

CO₂, ammonia, hydrocarbons. Proven for over a century. They don't warm the planet, and they don't leave a forever chemical behind.

Natural refrigerants avoid both.

Hidden pollutant

TFA: the forever chemical you haven't heard of.

Trifluoroacetic acid is an ultra-short-chain PFAS that forms as a breakdown product of synthetic refrigerants and accumulates in rainwater. Natural refrigerants don't break down into TFA.

Stage 1 · Emission

HFCs and HFOs leak from refrigeration systems.

Synthetic refrigerants escape over the lifetime of every system: installation, service, end-of-life. The leaks are small, but they add up across millions of installations worldwide.

Voices from the field

What operators say after a year on natural refrigerants.

Jean-François Vallée
VP Engineering
Congebec Inc.
Performance
How has the system performed over the past year?

The start-up and commissioning was very smooth and the system is very stable. After 7 months of operations, the system looks very energy efficient and we are anxious to compile all the consumption data's after a full year in service.

Marc-Antoine Bucci
Senior Director, Facilities Management, Automation and Projects
Groupe Robert Inc.
Performance
How has the system performed over the past year?

ZERO-C is Groupe Robert partner since 2018 when we started converting our refrigeration systems to CO₂. Since then, we are satisfied with the performance of our CO₂ systems.

Sylvain Gaudreau
Engineering Director
St-Hubert Group
Performance
How has the system performed over the past year?

CO₂ systems very well achieve the promised efficiencies with our pies freezing systems, such as a cooling spiral completely designed by Zero-C which cools very well according to initial calculations as well as our cooling blast which does even more than the basic calculations.
