Chiller Rooms

Infrared sensor technology provides long-term reliable monitoring in chiller rooms, with minimal maintenance and can be used with Manning Systems readouts or provide a linear 4/20 mA signal to a PLC.

Manning Systems sensors can monitor R-22, R-134a, R-404a, R-507, plus others. As new refrigerants come to the market, please call to discuss sensor placement and the relative sensitivity of each refrigerant gas blend.

Manning Systems can supply a single point gas sensor system, four channel system, or multi-channel unit that monitors as many as ten sensors at a single master safety control panel. All readouts have relay outputs to notify security personnel, activate fans, shut off valves or refrigeration equipment, etc. Sensors give a linear 4/20 mA output and can tie directly to a PLC or building control system.

The new AirAlert™ 96d multi-channel gas monitoring system adds addressable RS-485 Modbus communication protocol to the broad line of Manning Systems readout/alarm units. A total of 96 gas sensors and relay modules can be linked to a single controller.
