The Chillgard VRF Refrigerant Leak Detector is the first industry detector for Variable Refrigerant Flow Systems (VRF) with integrated BACnet capability. Therefore, it can be directly connected with any Building Management Systems (BMS). MSA applies its proven Photoacoustic infrared sensing technology that provides a stable zero baseline, minimizes cross-sensitivities and offers low cost of ownership through minimum maintenance required. •Low-level detection at 25 ppm minimum detection •Versatility—capable of operating within wide temperature and humidity ranges •Low maintenance—no moving parts and stable PAIR sensor technology •Easy installation—simply secure back plate to wall •20-year proven photoacoustic infrared sensing technology •Digital communications •BACnet® •Modbus Markets: Building/HVAC Variable refrigerant flow (VRF) systems use pure refrigerant as the cooling and heating medium, versus traditional 4-pipe air conditioning method using hot and cold water. A typical VRF system consists of an outdoor condensing unit that conditions and circulates the refrigerant within buildings to multiple fancoil units. A building could be conditioned by multiple VRF systems that deliver refrigerant at variable rates and exact amounts to spaces that need it, meeting building heating and cooling needs with increased precision and efficiency. Engineers and contractors prefer to design and install these types of systems due to their many benefits, including energy savings of up to 40% and personalized comfort.
