BHCR Hq · Flagship brand

Eco Kold. Our refrigerant, in the field.

Eco Kold is the brand that takes BHCR's HCR blend platform to market — natural hydrocarbon refrigerants that drop into the equipment the world already runs, at a Global Warming Potential of less than 1 (<1). It's the consumer- and commercial-facing face of everything we engineer.

What Eco Kold is

A drop-in retrofit, not a rip-and-replace.

Recover the old refrigerant, vacuum the system, and recharge by weight with the matching Eco Kold blend — retrofit-ready, with minimal to no equipment changes and a GWP of less than 1 (<1). Confirm charge size, system suitability, and oil compatibility against the per-gas compatibility guide before any replacement. The whole line is matched to the legacy gas it replaces:

HCR 4040 → replaces R-404 · R-513 HCR 4141 → replaces R-410A · R-32 HCR 4242 → replaces R-22 · R-407 · R-507 · R-438 · R-448 · R-449 HCR 4343 → replaces R-134 HCR 4343A → replaces R-134A
