Turn Refrigerant Leak Detection Into a Mission to Protect the Planet
More about our Mission
The Hidden Cost of Refrigerant Leaks
Refrigeration systems are responsible for nearly 2.5%
Up to 83% of their climate impact comes from 2 factors
40 tons of CO₂ emissions
Up to a 7% increase in electricity consumption
25% is the average refrigerant leak rate
$13k–$14k is the annual cost impact
Now multiply that by every cold room, cabinet, machine room, supermarket, and industrial facility across America, and the numbers are staggering.
- Increased risk of equipment failure, product spoilage, and non-compliance fines.
- Multiple ineffective truck rolls searching for leaks without any information, leading to hours or days of inefficient blind searches.

I have questions about your refrigerant leak detectors...
Why are your refrigerant leak detectors the best?
Our refrigerant leak detectors use gold-plated infrared sensors that detect even low levels of refrigerant leaks at 1 ppm, equivalent to 0.1 oz of gas.
They’re designed for accuracy, avoiding false alarms from humidity or chemical interference. The leak detectors continuously monitor gas concentration, and thanks to the high accuracy of the sensor, the system can show actionable insights to show the quantity of pounds being leaked, when, and where.
What is Refrigerant Leak Detection, and why is it important?
Refrigerant leak detection means identifying the gas concentration in the air.
Early refrigerant leak detection protects worker health, ensures regulatory compliance (EPA 608, NY 494), and prevents major refrigerant leaks that damage the environment by helping to reduce the leaks up to 95%.
How sensitive is AKOSentinel™?
Each gas detector detects refrigerant leaks from 1 ppm, which is the most sensitive leak detector available today, with an accuracy of 95%.
This, together with his high selectivity to filter any other gases, chemicals, or moisture, ensures a top-notch reliability on the information supplied.
What is the ROI for retailers?
Usually AKO Automatic Leak Detection solution pays for itself in less than two years, thanks to energy savings and reduced gas loss, and reduction of truck-rolls.
Does AKOSentinel™ provide automatic analytics?
Yes, our solution is equipped with automated leak detection reports, cost tracking, and performance optimization dashboards are all included.
Thanks to its powerful reporting, the insights will help to focus on what’s really important, understand which services and installations are the most problematic, check the trends and evolution of leaks in the whole chain…
How long has AKO been around?
AKO was founded in 1978 in Barcelona, Spain.
Our mission for more than 45 years has been to deliver sustainable, efficient, secure, and connected solutions for the refrigeration sector, and promote care for the planet and the people who live on it.
How does AKOSentinel™ detect refrigerant leaks faster than traditional methods?
AKO leak detectors feature NDIR sensor technology, capable of identifying refrigerant leaks instantly, even sudden changes, before pressure loss causes further refrigerant leaks or energy waste, or large and expensive gas recharges, or even product loss.
AKO leak detectors are capable of detecting leaks from 0.1 oz.
Can AKOSentinel™ reduce energy costs?
Absolutely. A 15 % refrigerant leak can increase energy use by 10 %, and this inefficiency grows exponentially together with the leak.
Our refrigerant leak detectors help systems maintain target temperature and energy consumption levels efficiently.
How does early leak detection ensure continuity?
By preventing refrigerant leaks, you safeguard product storage, prevent downtime, and comply with HCFC phase-down regulations, which are reducing the available quantity of these gases in the market, and, in consequence, increasing their price.
What industries benefit from AKOSentinel™?
Our solution is suitable for food retail, food service, cold storage, pharma, healthcare, logistics, and any facility relying on commercial or industrial refrigeration.
Can it monitor multiple sites?
Yes. Cloud-based leak detectors are scalable, visual, and easy to deploy across small or large networks.
The system allows to have top to bottom information and categorizes sites per performance, assigns roles and permissions from the site or even by service.
What's your refund policy like?
