Refrigerant Detector for Ground Source / Air Source Heat Pumps
Stand alone, single point Infra-red refrigerant detector and alarm unit ideal for small installations. Using infra-red technology the unit is specifically designed to measure very low levels of refrigerant gas in air. It eliminates the inherent problems associated with other methods of refrigerant detection such as semi-conductor and electrochemical sensors. The sensor is immune to poisoning or cross sensitivity and is a versatile and robust instrument.
Designed as a single point, self contained unit but can be connected to a central control panel for group alarms.
The unit is used to detect the presence of Freon’s or HFC’s in plant roomswhere a leakage of refrigerant gas may occur. The GD231 includes a diffusion filter, while preventing ingress of dust and other particulates allows the atmosphere to reach the optical bench of the instrument.
The LED multi colour array shows increasing Refrigerant levels and alarm trigger points.
Integral alarm relays, with 2 distinct trigger points can be used to start extraction fans and trigger alarm beacons.
Alternatively the 4-20 mA outputs from a group of sensors could be connected to a third party control system capable of providing indication of concentration levels and group alarms if required.
RS485, MODBUS output available for remote monitoring via an optional add on module.
It is a low maintenance sensor but has full auto zero function so requiring no calibration in the field.
