Refrigerant Leak Detection
Refrigerant gas leak detection is becoming a high priority for many companies, especially considering the increasing price of refrigerant gas, not to mention emergency service call-out costs to find, detect, and repair leaks of hydrofluorocarbons (HFC), chlorofluorocarbons (CFC), Ammonia, or CO2, and the potential for loss of inventory if a major leak renders a system inoperable.
In Europe, the last revision of the F-Gas directive actually mandates the installation of leak detector in industrial or commercial facilities running medium to refrigeration units, based upon the GWP (Global Warming Potential) and the nameplate capacity for the used refrigerant. It concerns:
- Food and beverage industry
- Dairy product processing and storage
- Large refrigerated warehouses (or grocery outlets)
Other sources of fugitive emissions of refrigerant gas are from refrigerant manufacturing plants, refrigerant storage or transfer stations. Area monitoring of these facilities can alert the proper authorities to initiate corrective action.
LumaSense Technologies’ Solutions
LumaSense Technologies provides quality solutions for area leak monitoring or leak detection with its IR spectroscopy portfolio. We have products and solutions to address:
For System Integrators
The Andros 6552 can address many of the needs of the integrator. It leverages our superior NDIR platform design with a specific configuration for refrigerant monitoring.
Up to three sample points and a dedicated zero channel can be supported directly with the on-board 12 VDC solenoid valve drivers. Additionally a 12 VDC pump can be directly operated by the 6552 or can operate a relay to operate AC pumps when higher flow rates are needed.
For End Users
The INNOVA 1314i can address the needs of end users with a unique area monitoring system featuring ppb detection levels thanks to the photoacoustic technology.
The trace gas detector INNOVA 1314i can be bundled with a multi-zone sampling systems with up to 24 channels.
Your Benefits – Infrared Solution Advantage
Our solutions, based on IR spectroscopy have definite operational advantages over leak detection system relying on arrays of electrochemical (EC) sensors. The IR technique essentially overcomes the following practical limitations of EC gas detection:
- Limited lifetime
- Damaged by exposure to high levels
- Lifetime depends upon integrated exposure
Cost-wise, an IR leak detection system can be optimized by using a central sampling station which sequentially pulls samples from multiple zones (corresponding to expected sources of fugitive emissions) into a unique analyzer / detector. For the system operator, besides an inherent longer lifetime of the sensing component, the routine maintenance (some calibration is required) is also simplified with a lower number of actual analyzers.
Overall a well-designed IR leak detection system provides a cost effective asset to monitor for refrigeration gas leaks in medium to large refrigeration systems.
In a fast moving regulation frame, LumaSense Technologies is continuously improving its portfolio to adjust to the market shift toward new and innovative refrigerants. Don’t hesitate to contact us for your specific needs.
