This timeline provides a chronological, verifiably sourced record of the regulatory environment concerning hydrocarbon refrigerants, alongside the corporate history of Eco Kold and BHCR. (BHCR marketing summary) For a focused explanation of where HCR 4141 stands in the EPA approval process today, see the dedicated HCR 410 and HCR 4141 EPA SNAP status page.

  1. ITESM Monterrey Safety Study Completed

    Panama Green Innovations S.A. commissions a safety risk study on the HCR 410 refrigerant formula at the Tecnologico de Monterrey. The study notes that HC refrigerants are highly flammable (A3 equivalent) but can be used with proper handling. This is the earliest documented activity of the corporate cluster.

  2. Eco Kold Version 1.0 Launched

    According to BHCR's corporate narrative, Version 1.0 of the Eco Kold refrigerant went to market and distributor partnerships began.

  3. UTP Efficiency Study Published

    The Universidad Tecnologica de Panama publishes a study showing a 36% efficiency gain for HCR 410 compared to R-410. An Eco Kold representative was present during the testing. This single study forms the foundation of all BHCR marketing efficiency claims to date.

  8. Oca Loca Commercial Installation

    BHCR converts a poorly-maintained 10-ton Daikin unit in Panama from R-410A to HCR 410. They log a 38% amperage reduction, though standard HVAC guidelines state that simply cleaning a dirty coil can achieve similar efficiency gains.

  9. Real-World Testing Fails in Israel

    After importing the product following BHCR's guarantees, Konstantin Rize conducts 6 months of testing on standard Israeli cooling systems. The tests fail entirely, not meeting any of the manufacturer's efficiency or functionality promises. BHCR breaks its promise to send a representative and refuses a fair financial settlement.
