## MSA Chillgard® RT Refrigerant Monitor

The **MSA Chillgard RT Refrigerant Monitor** is an industrial refrigerant gas monitoring
instrument designed for continuous leak detection in refrigeration systems, HVAC
facilities, and mechanical equipment rooms. Manufactured by MSA, this monitor uses
Photoacoustic Infrared (PIR) technology to identify compatible refrigerant gases
at low concentrations.

With a minimum detection capability of **1 ppm**, the Chillgard RT is designed for
applications where sensitive refrigerant monitoring is required. Its configurable
monitoring system can support up to eight remote sampling locations, allowing suitable
facilities to monitor different areas through a centralized instrument.

### Key Features

 * **Photoacoustic Infrared Technology:** Uses highly selective PIR technology for
   refrigerant gas detection.
 * **1 ppm Detection Capability:** Designed to detect refrigerant concentrations
   as low as 1 ppm.
 * **Multi-Point Monitoring:** Supports monitoring of up to eight remote sampling
   locations with the appropriate configuration.
 * **Multiple Refrigerant Options:** Can be configured for specific refrigerants
   or groups of compatible refrigerant gases.
 * **Three Alarm Levels:** Provides configurable caution, warning, and alarm functions.
 * **Visual Display:** Features an easy-view vacuum fluorescent display.
 * **Audible Alarm:** Includes an audio alarm for notification of detected conditions.
 * **Multiple Outputs:** Supports 4–20 mA and 0–10 V analog outputs.
 * **Building Management Integration:** Offers BACnet compatibility.

### Applications

The MSA Chillgard RT Refrigerant Monitor is designed for suitable monitoring applications
in:

 * HVAC and air-conditioning facilities
 * Industrial refrigeration plants
 * Commercial refrigeration rooms
 * Cold storage and transport facilities
 * Supermarkets and refrigeration equipment areas
 * Meat processing and packing facilities
 * Refrigerant storage locations
 * Mechanical equipment rooms

### Refrigerant Detection Capability

The Chillgard RT can be configured for a range of refrigerant gases. MSA documentation
lists refrigerants including R11, R12, R22, R123, R134a, R404A, R407C, R410A, R507A,
and other compatible gases. The exact refrigerants supported depend on the instrument’s
original configuration and calibration.

### Installation and Safe Operation

Install and operate the MSA Chillgard RT according to the manufacturer’s instruction
manual. Before installation, confirm the refrigerant type, sampling-point arrangement,
tubing requirements, power supply, alarm configuration, and output compatibility.
Regular inspection, calibration, and maintenance should follow the manufacturer’s
recommendations.

The monitor should form part of an appropriate facility safety system and should
not replace required ventilation, leak prevention, or emergency response procedures.
