R452b

R-452b is a non-ozone depleting, low global warming potential, HFO-based refrigerant to replace R-410a in positive displacement, direct expansion air conditioning, heat pump and chiller applications. It offers the optimal balance of properties while being easily convertible from R-410a designs.

  • Sensors:
    N.E.T can offer wide range of  NDIR sensors to monitorize refrigerants, in particular IREF-32 mm is suitable for detection of R1234yf gas in %LEL range (see datasheet)
  • Transmitter:
    All NDIR sensors  can be  mounted on a Cyber module that can drive and process the signals from the majority of N.E.T. industrial sensor range:
    CYBER – 4-20mA output
  • N.E.T Heads and N.E.T. Cyber Heads:
    N.E.T manufactures also a wide range of ready-to-use detector heads, that can house all NDIR sensors:
    NET3X or NETC3
    The NET3 Cyber Head (ATEX/IECEx certified) has been developed for use as a component of a fixed gas detection system or as a full conformity field device. It can accommodates a Cyber transmitter module with 4-20 mA and digital (RS485 Modbus) outputs. The electronics are connected to an infrared, pellistor or electrochemical gas sensor.
