CAREL GLD Small Gas Leakage Detector
Intelligent fixed refrigerant gas leakage detection for cold rooms, freezer rooms and commercial or industrial refrigeration systems. Available for selected HFC, HFO, hydrocarbon, R744 CO₂ and R717 ammonia refrigerants.
Continuous Refrigerant Leak Detection for Safer Refrigeration
The CAREL GLD Small Refrigerant Gas Leakage Detector is a fixed gas monitoring device designed to detect refrigerant leakage in environments containing commercial and industrial refrigeration equipment.
The detector continuously monitors the surrounding atmosphere and provides warning or alarm signals when the configured gas concentration thresholds are exceeded.
Featuring LED diagnostics, configurable alarm relays, analogue outputs, RS485 Modbus communication and Bluetooth connectivity through the CAREL RILEVA TE app, GLD Small can operate independently or integrate with compatible CAREL and third-party monitoring systems.

Typical Applications
Important Product Selection Information
Confirm the exact refrigerant, sensing technology, detector part number, gas concentration range and warning/alarm thresholds before ordering. A GLD Small detector must be selected, installed, configured and maintained according to the CAREL documentation and applicable safety regulations.
These GLD Small models are not ATEX-certified for hazardous classified locations. Semiconductor sensors may also respond to interfering gases or substances.
