CO2 Leak Detector

Planning / Implementation: Star Refrigeration Group
Refrigerant: Carbon dioxide (CO2)
System start-up: February 2010

Star Refrigeration in collaboration with Core Enterprises Inc. distributes the AccuTool eL-720 Carbon Dioxide gas leak detector. The eL-720’s long life sensor will detect concentrations of carbon dioxide gas as low as 400 ppm over ambient. False alarms are eliminated due to its high selectivity.


The global use of CO2 refrigeration systems is expanding exponentially. The demand was to find even the most difficult-to-find leaks and make the systems safer for the employee.


A full automatic, small size and high sensitivity detector, which is easy to handle and effective at locating even the most difficult-to-find-leaks. This CO2 leak detector is run with patented infrared cell technology. The infrared cell is far more advanced than any out there and cannot be duplicated due to CORE’s patents.
