A commercial refrigeration site with reheat circuits is repeatedly losing compressors, suspected due to non-condensables, with no reliable field method to confirm their presence.

Existing test methods are indirect, inconsistent, or require removing refrigerant to a tank; no field-usable diagnostic tool that non-destructively measures non-condensable concentration in a live system.

Workarounds Described

Pressure test on a recovery tank to compare actual vs calculated pressure
Running condenser fans to observe pressure behavior

Implied Software Gaps

A diagnostic tool that quantitatively measures non-condensables in a live system without refrigerant removal or complex calculations

App Concept

PureRefrig Diagnostic

A handheld analyzer that connects to a Schrader port and uses gas chromatography or a heat-of-mixing sensor to quantify non-condensables (air, nitrogen) in real-time without removing refrigerant. Provides a pass/fail reading and % by mass, enabling technicians to confirm the root cause and avoid needless component changes.

Key Features

Real-time measurement and display of non-condensable concentration
No refrigerant removal required
Temperature-compensated pressure comparison
Durable probe with standard Schrader connection
Store and share readings via smartphone app

Target Users: HVAC service technicians and field engineers troubleshooting commercial refrigeration and AC systems

Revenue Model: $1499 per unit hardware sale + optional $99/year calibration and data cloud subscription
