The natural refrigerant that just works in the systems you already own.
Eco Kold is an engineered hydrocarbon blend with a Global Warming Potential of <1. It's a direct, drop-in retrofit across five blends covering R-22, R-410A, R-404, and R-134/R-134A. Lower energy, lower emissions, longer equipment life. Already installed in hospitals, retail, and industrial facilities across the Americas, Europe, and Asia.
Refrigerant progression.
Four generations of refrigerant chemistry, each graduating past the last. ODP is Ozone Depletion Potential; GWP is Global Warming Potential.
Eco Kold blends are HC natural refrigerants: GWP under 1 and zero ODP. Meet the blend family →
The numbers we put on a customer's electric bill: metered, on the record, independent audit in progress.
We don't publish lab projections. Every efficiency claim on this site comes off a real customer's utility bill, measured by an independent auditor. The current measurement cycle is underway; results publish here the day they clear.

Five blends. One drop-in retrofit for nearly every system in the field.
Each Eco Kold blend is engineered to match the pressure, temperature, and oil compatibility of a specific legacy refrigerant, so installation is a recharge, not a retrofit.
Every refrigerant in commercial cooling, at the same scale.
Twelve synthetic refrigerants in active use today, ranked by Global Warming Potential. The single Eco Kold mark at the bottom is the entire HCR product line: every blend at GWP <1. The legacy gases climb to nearly 4,000.
GWP values from the BHCR Refrigerant Replacement Comparison Chart, aligned with IPCC AR5 100-yr GWP figures. Full background, regulatory timeline, and replacement matrix →
One column does the work of two thousand.
The skyline above shows the gap across all blends. Below is the same gap, broken down across the four metrics that matter for an air-conditioning retrofit: HCR 4141 against R-410A, the most common pairing.
A refrigerant should make the planet cooler, not warmer.
BHCR Hq has been engineering hydrocarbon refrigerants in Delaware and Panamá since 2009. Eco Kold replaces the synthetic gases responsible for an estimated 7.8% of global greenhouse-gas emissions.
