3 Description
The Chillgard 5000 provides continuous monitoring of refrigerant gas levels for up to 16 points in
nonhazardous areas. With the ability to read down to 1 ppm, the device provides a response to a
refrigerant leak, supporting the safety of personnel and the environment, and equipment efficiency.
The device uses patented Photoacoustic Infrared technology to allow the accurate measurement of
refrigerant gases with minimum interference from other vapors. The device monitors refrigerant gases
up to 1000 ppm with an ability to maintain a gas list through an internal refrigerant library.
The Chillgard 5000 minimizes unnecessary maintenance costs associated with calibration and
sensors by utilizing a centralized sample draw system. The device is factory calibrated for six specific
refrigerants, with the flexibility to adjust the gas of interest in the field.
The device offers three levels of alarm—caution, warning, and alarm—that are all configurable
through the intuitive touchscreen display. Fault and service notifications provide alerts when servicing
is necessary. Audible and visual indications such as horns and strobes provide alerts about refrigerant
leaks.
Digital communications can be transmitted using the Modbus remote terminal unit (RTU) or BACnet™
master/slave token passing (MS/TP) protocol. Analog communications can be transmitted using a
4–20 mA or 0–10 Vdc current loop.
The Chillgard 5000 requires minimal maintenance and incorporates predictive diagnostics that contin-
uously check key detector components to ensure proper operation. When the device is installed, oper-
ated, and maintained according to MSA's recommendations, it provides reliable protection and long-
term stability.
