R404a is comprised of a non-ozone depleting, designed as an alternative to long-term of R502  and R22 in the low and medium temperature commercial refrigeration. R404A is a good substitute in applications, such as refrigerated cabinets of supermarkets, cold storage rooms, display units, refrigerated transport and machines for the production of ice.

  • Sensors: 
    N.E.T can offer wide range of  NDIR sensors to monitorize refrigerants, in particular IREF-32 mm is suitable for detection of R404a gas in ppm range (see datasheet).
  • Transmitters: 
    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:
    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.
