    A2L Refrigerants

    A2L refrigerants represent the future of HVAC and refrigeration, offering dramatically lower global warming potential than traditional HFCs. However, their mild flammability classification creates new detection requirements. Equipment manufacturers and building codes are updating to address these refrigerants. CET is at the forefront of A2L detection technology, offering sensors specifically designed for the unique properties of these next-generation refrigerants.

    Why Detection Matters

    The AIM Act and EPA regulations are phasing down high-GWP refrigerants, driving rapid adoption of A2L alternatives. Unlike traditional refrigerants, A2Ls require detection for both flammability and oxygen displacement. UL 60335-2-40 mandates refrigerant detection in equipment rooms. Building codes are being updated to require A2L detection systems. Early adoption of proper detection ensures compliance as regulations evolve.

    Common Hazards:

    Mild flammability in high-concentration scenarios
    Oxygen displacement in enclosed spaces
    Decomposition products if exposed to flames
    Ignition risk from electrical components

    Regulations & Standards

    ASHRAE Standard 34 A2L classification, UL 60335-2-40 detection requirements, AIM Act HFC phase-down, EPA SNAP program approvals, IMC and UMC refrigerant detection requirements
