Haloguard I Refrigerant Leak Detection Monitoring System

Overview

Haloguard Low Cost 24-hour Leak Notification for Refrigeration Systems Refrigerant Leak Detection and Monitoring Systems

HALOGUARD ® is the cost effective, reliable way to reduce costly refrigerant leakage. With a HALOGUARD ® leak monitor installed, you quickly know where the leak is located and how much refrigerant you are losing. This exclusive early warning system detects leaks in a designated area and flashes a bright red LED when parts-per million (PPM) reaches the alarm level you preset. With a dialler or other remote signal hookup, maintenance personnel will know immediately when and where a leak occurs. Repairs can be made quickly, before you lose costly refrigerant or perishable products. An optional analogue output is available to interface with EMS/BMS systems.
