REMORA MTC

THE NEW MTC OEM REFRIGERANT SENSOR MODULE

  • Reliable detection of A2L Refrigerants
  • Local relays for threshold alarms
  • RS-485 Modbus communication
  • NET MTC molecular thermal conductivity technology
  • No false alarms, no regular maintenance required
  • 15+ years of expected lifetime

The new REMORA MTC from NET is a complete, ready-to-use and cost-effective sensor module aimed at making refrigerant leak detection easy, affordable and effective in any application scenario.

REMORA is based on a glass reinforced, flame retardant IP54 Polyamide enclosure, complete with integrated mounting holes. The gas inlet is protected by an oleophobic filter and oil spray cover. All this ensures maximum protection against shocks, dust and contamination in any possible environment and application scenario.

REMORA gas detection is based on NET range of  MTC sensors. MTC detection ensures poison immunity, fail safe operation, long term stability and extended lifetime (15+years). The sensing part is microprocessor based, providing a linearized, temperature, humidity and pressure compensated reading, as well as complete diagnostics information while running constant self-check and self-calibration routines.

The REMORA module has a high-level interface with industry-standard MODBUS protocol on RS-485, as well as local threshold for alarm outputs and optionally. The power supply rating is 12…24VDC or 24VAC. The unit can be customized with different interface options, such as PokaYoka Automotive connector, NET standard connector and cable.

All the above makes the Remora sensor an ideal solution for any refrigerant leak detection applications, from direct integration in HVAC/R equipment such as chillers, rooftop units or heat pumps, to environmental monitoring in cold rooms, machinery rooms or refrigerated transports as well as occupied spaces such as hotel rooms, hospitals or office buildings.
