Built by refrigeration specialists, for the technicians on the floor.
Built for supermarket rack systems
Guided Diagnostics
Step-by-step decision trees built for parallel-compressor racks — from suction imbalances to oil, head pressure, and controller alarms.
AI + Photo Diagnose
Snap a pressure gauge or controller screen and the AI reads it — describe or photograph the problem and get a diagnosis on the spot.
Searchable Fault & Alarm Library
Look up faults and controller alarm codes fast — Danfoss (AK-PC, AK-SC), Emerson/CPC (E2, Einstein), Dixell and Carel.
Deep CO₂ & R-290 Reference
Transcritical CO₂ (R-744) pressure/temperature charts and R-290 (propane) safety procedures — the modern refrigerants, done right.
Works Offline + PDF Export
Diagnostics and reference are cached for zero-signal machine rooms, and every diagnosis exports to a branded, work-order-ready PDF.
A real diagnostic. Start to finish.
