Designed to meet ASHRAE 15 and other building code requirements for mechanical rooms, MSA has released the new Chillgard® 5000 Refrigerant Leak Monitor. With the ability to read down to the 1 ppm level, MSA’s Chillgard 5000 provides an early response to HVAC refrigerant gas leaks, which allows maintenance crews to respond more quickly and to avoid the consequences and costs of hazardous gas leaks. Refrigerant gas is considered a toxic gas and although refrigerants have low toxicity, at high concentrations they can displace oxygen. Serious injury or death can result from worker oxygen deficiency.

The Chillgard 5000 Leak Monitor can detect up to six different field-selectable refrigerants and be configured with a choice of four, eight, or 16 sampling points. It features MSA’s photoacoustic infrared (PAIR) sensor technology, which is largely unaffected by temperature or humidity to reduce drift and increase accuracy without frequent adjustment or maintenance. It has been independently third-party tested to the 1 ppm level over temperatures of 32-122°F (0-50°C) and 0-95% rh levels. 

In the event of a gas leak, the Chillgard 5000 provides a clear visual and audible signal to indicate there is a potentially dangerous, environmentally-harmful and expensive leak. Available gases include 20 of the industry’s most common refrigerants monitored over an operating range of 0 to 1,000 ppm. Sensor response time at less than 90% of gas reading is under 70 seconds.  

With an all new intuitive user interface, the Chillgard 5000 features a large 7-inch touchscreen color display with real-time dashboard text and graphics.  It is password protected for security, the text is viewable in six languages, and its diagnostic and event logs make for easy inspection and maintenance.  Calibration is completed at the touch of a button using the designated calibration port.
