Thermal Gas Systems: Refrigerant Monitor
June 29, 2001
The Haloguard(r) III, a multichannel, multigas system, from Thermal Gas Systems (Roswell, GA) is designed to continuously monitor R-11,-12,-22,-134a,-123, and other commonly used refrigerants. Up to two additional, remote separate IR modules may be located up to 1,000 ft from the central controller, and the user can adjust min/max alarm levels independent for each sensor. Independent 4- to 20-mA or 0- to 10-vdc analog outputs can communicate with a computer-controlled energy management or building automation system.
