R-449 is a non-ozone depleting, low global warming potential (GWP) hydrofluoro-olefin (HFO) based refrigerant replacement for R-404A/R-507, R-407A/F, and R-22 for new equipment and retrofit of existing systems.
N.E.T can offer wide range of NDIR sensors to monitorize refrigerants, in particular IREF-32 mm is suitable for detection of R449 gas in %LEL range (see datasheet)
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.
