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.

Founder

In the words of the people who built it.

We applied to renew the ATMOApproved Label because our commitment to natural refrigerants remains central to everything we do. Climate mitigation is not a one-time initiative for us, it is built into how we approach refrigeration. We focus on delivering high quality natural refrigerant systems, improving performance and efficiency, and helping our customers reduce their environmental impact. Being re approved by ATMOsphere reflects the consistency of our work and reinforces our commitment to maintaining best in class standards.

Performance
How has the system performed over the past year?

This system has effectively supported our operations for the past 1.5 years and continues to meet our expectations. It is recognized for its safety and high energy efficiency. While it is still too early to provide a comprehensive review - given Canada’s diverse climatic conditions - the system has generally performed well, delivering great outputs.

Quality & Reliability
How has the build quality and reliability held up?

I would rate the equipment 4 out of 5. Unlike other systems, it requires some time to adjust to operational changes, demand fluctuations, and external factors. As a result, we have occasionally observed alerts, which may be due to initial bugs or system adjustments. Importantly, no breakdowns or recurring issues have been observed.
