R1234yf  was proposed as a candidate to replace R-134a as the refrigerant in car air conditioners.
The fluid “R-1234yf” is part of a new class of refrigerants ready to replace chlorofluorocarbons and hydrofluorocarbons in air conditioning systems for automotive applications. The fluid “R-1234yf” has a global warming potential (GWP) of 4.

  • 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 ; NETC3;  NET3/PL.  
    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.
