Offered in single-point diffusion and 4-point pumped models, Chillgard LS Monitors have water-resistant plastic enclosure and can detect R11, R12, R22, R123 and R134A refrigerants, as well as 400 and 500 series. Chillgard LC Control Module works with Chillgard LS gas sensor modules to provide remote signaling and control.



Original Press Release:


MSA Chillgard® L Series Monitors Detect Additional Refrigerants


MSA Chillgard L Series Refrigerant Monitoring Systems are now able to detect many 400 and 500 series refrigerant gases. As the Chillgard L Series Monitor already detects many common refrigerants, this added capability offers an unprecedented mix of performance, flexibility and value to satisfy many refrigerant detection needs. All Chillgard L Series Monitors utilize photoacoustic infrared sensing technology that the HVAC industry has come to expect from MSA. Designed with a focus on flexibility for a variety of applications and installations, all units are easy to install and operate, and additional sensor modules can be added to the system later as needed. Chillgard L Series Monitors are UL listed and comply with ANSI/ASHRAE 15-1994 requirements for entryway signaling and refrigeration monitoring.

The Chillgard LS Photoacoustic Infrared Refrigerant Monitor is housed in a water-resistant plastic enclosure and provides economical, low-level monitoring. Featuring high performance, sensitivity and stability, the Chillgard LS Refrigerant Monitor can detect the five most common refrigerants (R11, R12, R22, R123 and R134A) as well as the 400 and 500 series, and is available in both single-point diffusion and 4-point pumped models. This monitor can work either on a stand-alone basis or in conjunction with the Chillgard LC Control Module. With optional plug-and-play optical benches available, the Chillgard LS Refrigerant Monitor can easily be configured to detect a different refrigerant at a later date.

The MSA Chillgard LC Control Module works with the Chillgard LS gas sensor modules to provide remote signaling and control capability in refrigerant monitoring applications and can communicate with up to eight sample points from the Chillgard LS Refrigerant Monitor over an RS-485 communication line.
The Chillgard LE Monitor combines all of the benefits of the Chillgard LS Monitor and Chillgard LC Monitor in one enclosure. The Chillgard LE Refrigerant Monitor can be purchased as a single-point diffusion unit (no internal pump), single-point pumped unit (for monitoring from a remote location) or a four-point pumped unit. As with the Chillgard LS, detection of a different refrigerant gas requires only a change of optical benches.

Common refrigerant gas monitoring applications include mechanical equipment rooms, propellant filling operations, solvent cleaning stations, cold storage and transport facilities, meat packing plants, supermarkets and refrigerant storage locations.
