*Not required by the UL standard; therefore not evaluated by UL.
- Enables hydrofluorocarbon (HFC) phasedown using A2L refrigerants less than 750 GWP.
- Uses Micro-Machined Membrane (MMM) technology.
- Sensors can be calibrated for R-32 and R-454 blends.
- Meets all AHRTI testing requirements including vibration testing, and is proven to be best-in-class.
- Immune to poisoning: Insensitive to poisoning from chemicals listed in UL-60335-2-40 Annex LL.
- No calibration / maintenance: No false alarms due to ambient conditions with the built-in environmental sensor for temperature, humidity, and pressure.
- Resistant to condensing environments
- Long life span: 15+ years
