The Chillgard 5000 Refrigerant Leak Monitor from MSA is designed to meet safety, environmental, and building code requirements for mechanical rooms. With the ability to read down to the 1 ppm level over temperatures of 32°F to 122°F and 0% to 95% relative humidity levels, it 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 can detect up to six different field-selectable refrigerants and be configured with a choice of four, eight, or 16 sampling points. This refrigerant leak monitor 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.
In the event of a gas leak, the Chillgard 5000 provides a clear visual and audible signal. Available gases include 20 of the industry’s most common refrigerants monitored over an operating range of 0 to 1000 ppm. Sensor response time at less than 90% of gas reading is under 70 seconds. Built-in diagnostics support predictive maintenance for worry-free use.
The Chillgard 5000’s intuitive user interface has a 7″ 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.
The Chillgard 5000 Refrigerant Leak Monitor operates independently or is compatible with multiple building management systems (BMS). It includes integrated BACnet and Modbus for direct digital communication back to a centralized control system. BACnet protocol allows for non-intrusive gas concentration monitoring and alarm status. No configuration is necessary because the data is automatically mapped into the database upon protocol selection.
This complete Chillgard system keeps users in compliance with ASHRAE 15 by offering a variety of horns and strobes for entryway signaling. The Chillgard 5000 is equipped with five internal relays for fault, three levels of alarm, and an external horn option. Installation requires 24 Vdc/Vac power, there are no moving parts for low maintenance, and only an annual calibration check is recommended.
