MSA’s Chillgard 5000 leak monitor expands refrigerant gas library

MSA Chillgard 5000The MSA’s Chillgard 5000 Refrigerant Leak Monitor is designed to meet safety, environmental, and building code requirements for building mechanical rooms

The Chillgard 5000 reads down to 1 ppm. This reliable, reliable gas monitor provides an early response to HVAC refrigerant gas leakage, allowing maintenance crews to respond more quickly and avoid the consequences and costs of hazardous gas leakage.

The refrigerant gas is considered to be toxic, and although refrigerants generally have low toxicity, they can displace oxygen at high concentrations. Serious injury or death may result from a worker’s oxygen deficiency.

With its versatile design, the Chillgard 5000 Gas Monitor can be configured to monitor up to six different field-selectable refrigerants and with a choice of 4, 8 or 16 sampling points.

It features MSA’s breakthrough photoacoustic infrared (PAIR) sensor technology, largely unaffected by temperature or humidity to reduce drift and increase accuracy—without frequent adjustment or maintenance. It was independently tested at 1 ppm at temperatures between 32-122°F (0-50°C) and 0-95% relative humidity.

Should a gas leak occur, the Chillgard 5000 provides a clear visual and audible signal to indicate there is a potentially dangerous, environmentally harmful, and expensive leak. The expanded library of available gases now includes 38 of the industry’s most common refrigerants monitored over an operating range of 0 to 1000ppm. Sensor response time at less than 90% of gas reading is under 70 seconds.

Built-in diagnostics support predictive maintenance for worry-free use.

With an intuitive user interface, the Chillgard 5000 features a large 7-inch (178 mm) touchscreen colour display with real-time dashboard text and graphics, as well as an optional remote display to help meet ASHRAE 15 and EN 378 standards.

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 includes a choice of popular communication outputs: 4-20 mA, RS-485 Modbus, RS-485 BACnet MS/TP, BTL. Integrated BACnet and Modbus capability provide digital communication back to a centralised BMS control system. The BACnet protocol allows for the monitoring of non-intrusive gas concentration and alarm status. No configuration is necessary because the data is mapped to the database automatically when the protocol is selected.

With the Chillgard 5000’s predictive diagnostic capability, users are alerted in advance when it’s time to service the sensor, pump, or flow systems before unexpected failure. Calibration is performed away from the sample environment for safe, easy access reducing time spent on maintenance.

The Chillgard 5000 is equipped with five internal fault relays, three alarm levels and an external horn option. Installation is simple and requires 24 Vdc/Vac power. There are no moving parts for low maintenance, and an annual calibration check is recommended.
