Thermal Gas Systems Inc- The Haloguard Series

Supplier: Air-Met Scientific

The Haloguard Series (I, II & III). Detection systems for refrigerant gases.

Price Guide: POA

Haloguard I & II

The HALOGUARD® II/IR combines microprocessor based controller with highly selective and sensitive remote photo-acoutstic infrared modules to provide the most advanced system for detecting the presence of halocarbons.

The multi-channel controller monitors IR modules or 02 sensors in up to six separate locations, then provides both local and remote notification when gas concentration reaches preset alarm levels. Alarm relays and analog outputs are built in to activate remote devices or to interface with an energy management (EMS) or building automation (BMS) system.

Haloguard III - a Photoacoustic Infrared, Multichannel and Multigas Detection System for Refrigerant Gases.

The Haloguard III combines an advanced microprocessor based digital signal processing and a wideband photo-acoustic infrared cell to provide the newest most advanced system for continuous monitoring of all refrigerant gases.

The Haloguard III monitors single or multiple, local and remote locations and provides notification when gas concentration reaches preset alarm levels. Up to 24 different gases may be monitored simultaneously by adding optional channel scanners and remote IR modules. Alarm relays and analog outputs are designed to activate remote devices or to interface with an building automation (BAS) system.

For selective refrigerant detection and sensitivity of 1ppm, we recommend the Haloguard II. This unit comes in the same housing as the Haloguard III and has simular in and outputs.
