R417a

R417a has similar physical properties to R22 however it has been formulated to enable it to be used with traditional mineral oils or alkyl benzene lubricants. This property makes R417A ideal for use in existing equipment but also suitable for use in new equipment without the need to change to the more expensive and hygroscopic polyol ester lubricants. It is an HFC retrofit refrigerant for R22 in direct expansion stationary air conditioning (AC) and medium temperature commercial refrigeration systems.

  • Sensors:
    N.E.T can offer wide range of  NDIR sensors to monitorize refrigerants, in particular IREF-32 mm is suitable for detection of R407a gas in ppm 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 NETC3The 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.
