A Managed Leak Detection Service
A Dedicated Partner, Not Just a Vendor
Our journey starts with an audit by our team of expert technicians, who bring 45 years of experience to the table.
Let yourself be guided by our engineering team that knows where refrigerant leaks happen, how to classify them quickly, and how to act efficiently.

Built for Performance
Our refrigerant gas leak detectors have been designed to maintain your facility under control, and are specifically designed and equipped to deliver superior performance.

- Gold-coated infrared sensor: selectivity, accuracy & durability.
- Avoids false alarms from other gases✓ IP65-sealed to prevent moisture-induced false readings✓ Anti-condensation algorithm for sudden changes in temperature, to ensure no false alarms happen.
- Operating temperature range down to –22 °F.
- Ultra sensitive leak detection from 1 ppm (EPA compliant)
- 3 alarm levels with dual relays
- 2 alarm relays included in each detector for pre-alarm & alarm
- Real-time refrigerant leak data logging & calibration tracking
- Calibration log to meet EPA requirements
- Integrated NB-IoT wireless communication
- Compatible with all common refrigerants
- Rugged design & construction for durable performance
- UL Listed
- 3-Year Warranty

Support in Configuration & Commissioning
As a result of our experience with hundreds of clients and installations, our technicians can help you determine which alarms and parametrization are most suitable according to the type of service you have.
Our technicians will also help you customize alarms and automate reports.

O&M Insights
Our goal isn’t just about installing refrigerant leak detectors—it’s about analysis, smart decision-making, and quick, effective action.
A proactive approach not only minimizes risks but also keeps your operations running smoothly and safely.


Calibration
Less than 1% of the refrigerant leak detectors in service in the market today are properly calibrated.
Our goal is to calibrate 100% of refrigerant leak detectors, to take care of the calibration for you, so you don’t have to worry about a thing.
AKO offers 2 possibilities:
- On-site calibration
- Sensor replacement
