Refrigerant leak detection for supermarkets and grocery stores.
Most supermarket leaks aren’t found by a detector. They’re found when a technician adds refrigerant, again. KalderIQ watches every connected rack continuously and flags the patterns of a system losing charge, often while it is still well charged.
Why supermarket leaks go unnoticed.
A large rack can lose hundreds of pounds before anything alarms. Room detectors only catch refrigerant that reaches them. Annual leak checks only catch what is leaking on the day. Each service call fixes the leak it finds, and nobody sees that the same rack needs a top-up every few months.
Continuous analysis sees the pattern across months, not a single visit.
How KalderIQ finds leaks.
KalderIQ reads operating data from your refrigeration controllers and looks for the signature of lost charge. Each rack gets a leak probability, the detection method that raised it, an estimated leak rate and the time it was last observed. Findings are ranked across all your stores, so your team starts with the rack that matters most.
- No new sensors needed in every case: it works from controller data
- Leak reports you can share with your contractor
- History that shows whether a repair actually stopped the loss
Leak detection and the 2026 EPA rules.
Under EPA’s AIM Act rules, HFC systems with 15 lb or more of refrigerant must be repaired within 30 days once the leak rate passes 20% for commercial refrigeration, and any system that loses 125% of its charge in a year must be reported. Catching a leak before the next big top-up keeps the leak rate down, the refrigerant bill down and the paperwork short.
KalderIQ is a detection tool, not a record-keeping system. Your refrigerant service records still come from your technician.
The leak that kept coming back.
A distribution warehouse rack holding about 1,200 lb of R-407F needed 400 to 600 lb top-ups roughly three times a year, for three years. Every visit found and fixed a small leak. Within two weeks of going live, KalderIQ flagged an active loss. The trend continued after two more repairs, so the team escalated. The real source was hidden on top of a cooler, behind a product box. Once it was repaired, the recurring top-ups stopped.
At that rate, the rack was adding about 1,500 lb a year, right at EPA’s 125% chronic-leak reporting line.
The proof.

Common questions
Can refrigerant leaks be detected without installing leak detectors?
Yes, indirectly. KalderIQ analyzes the operating data your refrigeration controller already records to spot the pattern of a system losing charge. Direct detectors are still useful in machine rooms and walk-ins; the two approaches catch different leaks.
How early can KalderIQ detect a leak?
It depends on the size of the leak and the data available. In our leak study, KalderIQ flagged an active loss within two weeks of going live, while the rack was still well charged.
Does KalderIQ find the exact location of the leak?
No. It tells you which rack is losing refrigerant and how strongly the data points to a leak. A technician locates and repairs the leak on site.
Does KalderIQ file EPA leak reports for us?
No. KalderIQ helps you find leaks early and gives you leak reports and history. Your leak rate calculations, repair records and any EPA reports are kept by your technician or compliance system.
