Refrigerant Gas Monitoring System

Flexible system provides early warning of refrigerant leaks.

Carrier has teamed up with Yokogawa Corporation of America to offer a flexible, effective refrigerant monitoring system that's designed to meet your needs now and for years to come.

The HGM200 continuously monitors your HVAC system for refrigerant gas and issues an early warning signal when a leak is detected. This allows operators to make timely repairs, thus avoiding significant, costly refrigerant loss and unsafe working conditions. ASHRAE Std. 15-1994 specifically recommends the use of refrigerant monitors.

Through infrared detection, a single HGM200 unit can monitor multiple gases in several locations. Up to 31 different locations can be selected for monitoring, and the HGM200 can be configured to monitor the gases you select from a built-in menu of compounds. The HGM200's unsurpassed flexibility is the result of the advanced software and the electronics associated with infrared detection. Easy to configure, the HGM200 provides a single unit approach to total system monitoring regardless of the type or number of the gases present. As new, alternative refrigerants are developed, the system can be expanded simply by inserting updated software.
