Refrigerant Leak Detection System (RLDS)

High Precision Refrigerant Monitor

RLDS

The Most Effective Refrigerant Monitor in the Industry

RLDS delivers the best refrigerant monitoring available, with industry-leading MDL (minimum detectable level) of 1 ppm for halogenated gases, the fastest sampling frequency and the widest range of refrigerants accurately detected. The large graphic LCD display and LED status indicators provide a system-wide overview at a glance.

RLDS enhances effective refrigerant management

The RLDS enhances effective refrigerant management, detecting leaks early to enable cost savings by reducing refrigerant discharge, enhancing energy effi ciency and reducing risk of refrigeration failure and product loss. A variety of communication interfaces are available, including Modbus, BACnet and LonWorks, allowing easy integration into BMS systems and remote monitoring solutions.
