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.

Secon was one of the first companies to apply for and receive the Atmo Approval. Since our company was founded in 2010, we have used only natural refrigerants and see ourselves as pioneers in the exclusive implementation of sustainable refrigeration technology. The continuous renewal of the Atmo-Approval is a matter of course for us and an important building block in creating trust in us and our products.

Performance
How has the system performed over the past year?

Yes, it absolutely has. After we replaced our old equipment (coolers/freezers) and replaced the unsustainable Freon cooling system with a CO2 cooling system, our energy usage and maintenence cost has drasticly decreased.
