Leak Detection in Occupied Spaces

Protect Guests from Refrigerant Leaks

High-efficiency Variable Refrigerant Volume / Variable Refrigerant Flow (VRF / VRV) systems are designed to be leak free, but improper installation, inadvertent damage and mechanical wear can result in potentially harmful refrigerant leaks. Effective refrigerant leak detection helps minimize the risks associated with large leaks associated with these systems in occupied spaces.

Leading the Industry and Ahead of the Codes

Around the world, local codes such as BREEAM, EN 378, ASHRAE 15 and ASHRAE 147 continually evolve to address the safe and environmentally conscious use of refrigerants. The use of the MVR-300 in occupied, conditioned spaces can detect a refrigerant leak well before the Refrigerant Concentration Limit (RCL) with alarm set-points as low as 500 ppm consistent with ASHRAE provisions for fixed refrigerant detectors to enhance safety.

The MVR-300 design builds on the success of the IAM-100 and more than 100 years of industry experience in the design & manufacture of gas detection instruments.
