EARLY LEAK DETECTION
Catch Leaks Months Before Temperature Alarms.
Reduce refrigerant leak rates by using a “Whole System” Automatic Leak Detection (ALD) system to detect refrigerant leaks early. EPA, CARB, NY, and WA compliant. No new hardware or sensors required.

THE PROBLEM WITH TRADITIONAL LEAK DETECTION
Existing methods don’t detect leaks until it’s too late.
Most leaks aren’t detected until the appliance has already lost most of its refrigerant and temperature alarms are flashing throughout the facility.
Alarms Trigger Too Late
Hardware-based refrigerant gas sensors only detect leaks within close proximity, and many gas sensors in use today are dirty or uncalibrated, leading to ignored alarms. Often,
50-70% of the total charge leaks before repairs. Then, you have an EPA event and emergency service calls
AIM Act Compliance Is Manual
The AIM Act requires operators to track
leak rates, log service events, and file
reports for HFC systems exceeding
regulatory thresholds. Managing this
manually across dozens of sites creates
significant compliance risk.
Refrigerant Loss Is Expensive
A 250-lb 404a leak can cost $5,000–$10,000
in refrigerant replacement alone — before
labor, emergency service premiums, or
product loss. With EPA fines, a single
unreported event can cost tens of
thousands more.
REGULATORY COMPLIANCE
Built for AIM Act. Ready for What's Next.
The AIM Act (American Innovation and Manufacturing Act) mandates specific leak rate thresholds, service timelines, and record-keeping requirements for commercial refrigeration operators. Axiom
automates all of it.

THE PATENTED METHOD
Leak Detection Without New Sensors.
Axiom's Early Leak Detection module is protected by U.S. Patent 12,359,856
— a novel method for detecting refrigerant leaks using behavioral analysis of
existing compressor and controller data. No new sensors. No new hardware.
No site visits to activate.
The system continuously monitors dozens of signals — suction pressure,
discharge pressure, superheat, subcooling, compressor runtime, refrigerant
circuit temperatures — looking for the coordinated deviation patterns that
precede a leak event. Traditional sensors look for refrigerant in the air. Axiom
looks for what the compressor is telling you first.
Patented multi-signal correlation: suction pressure + superheat + compressor
behavior analyzed simultaneously
Site-specific baselines built over the first 30 days —
detects deviations from
your
normal, not industry
averages
Leak confidence scoring: low / moderate / high / critical, with explanation of
contributing signals
Estimated leak rate in lbs/day calculated continuously from refrigerant circuit
behavior
$70K
Maximum EPA fine per violation per day for knowing AIM Act violations —
automated logging eliminates the risk of unknowing non-compliance
100%

requirements with zero additional FTE after full deployment

AIM Act service window from threshold detection to required repair —
Axiom's advance warning means you're scheduling service, not scrambling

COMPLIANCE AUTOMATION
AIM Act Records. Built While You Sleep.
Every refrigerant service event, every leak detection, every compliance
threshold calculation — Axiom logs it automatically and formats it for
regulatory reporting. No manual record-keeping, no compliance coordinator,
no risk of a missed filing.
Automatic leak rate calculation per system per year — formatted to AIM Act
reporting standards
Service event log with refrigerant addition quantities, technician notes, and
date/time stamps
Annual compliance report generated on demand — ready to submit or provide to

Refrigerant leaks caught before

"We used to find out about a refrigerant leak when either the alarm went off or the case started warming up — both of which meant an emergency service call and usually a regulatory event. Since we deployed Axiom, our facilities team gets a heads-up 7 to 10 days before it would ever become an issue. We schedule a routine service call, the tech fixes a fitting or a valve, and we're done. In the last 18 months we haven't had a single EPA reportable event across 68 stores."

pressure deviation, superheat change, compressor runtime
increase — overlaid on a single timeline view.
Leak Rate Estimate in Real Time
Axiom continuously estimates the leak rate in lbs/day based
