cGas Detector VRF IR "“ Advanced Safety for Modern HVAC Systems
Provides continuous monitoring for acute refrigerant leaks in modern energy-efficient buildings utilizing Variable Refrigerant Flow (VRF) HVAC systems.
Experience peace of mind with the cGas Detector VRF, your reliable safeguard for modern comfort systems. Designed for acute leak detection in buildings utilizing Variable Refrigerant Flow (VRF) HVAC systems, it ensures occupant safety by meeting ASHRAE 15-2024 and CSA B52 standards. With alarm setpoints set well below the Refrigerant Concentration Limit (RCL), you get early leak detection without unnecessary false alarms—keeping your occupants safe and space compliant, and worry-free.
Early Leak Detection for Safer, Energy-Efficient Spaces
VRF systems are increasingly popular for their energy efficiency, zoning flexibility, and reduced operational costs. However, refrigerant leaks pose serious risks:
- Health & Safety: Accumulated refrigerant can displace oxygen, creating asphyxiation hazards.
- Regulatory Compliance: Standards like ASHRAE 15-2024 and CSA B52:23 mandate leak detection in occupied spaces.
- Operational Continuity: Early detection prevents costly downtime and equipment damage.Key Features: Acute refrigerant leak detection with long-life (~10 years) dual-beam NDIR sensor.
- Alarm thresholds designed to trigger ventilation, isolate refrigerant lines and activate remote alarms.
- Integration Ready: Supports BACnet® MS/TP and Modbus® RTU for seamless BAS connectivity.
- Flexible Outputs: Configurable analog (4—20 mA, 0—10 V, etc.) and digital (Modbus® RTU or BACnet® MS/TP)
- Plug & Play Smart Sensor Technology for easy installation and maintenance.
- Field-Friendly: Fully configurable and firmware-updatable in the field using a USB stick.CGAS-AP-IR Analog Models One field configurable 4 - 20 mA analog or 0 - 10 V output, one relayCGAS-DP-IR Digital Models Modbus® RTU RS-485 or BACnet® MS/TP RS-485 digital output signal, one relay
