A diagnosis you can justify

KCE does not guess: it evaluates your readings against 251 technical rules written by refrigeration engineers and returns the most likely cause together with the reasoning. No generative AI, no cloud, and no different answers to the same data.

  • Deterministic: same readings, same result
  • Every conclusion shows the measured value and the expected one
  • 61 recommended actions tied to the rules
  • Derived variables: superheat, subcooling, compression ratio
  • Works fully without signal, in the plant room or the cold store
Real KCE screen: diagnostic result showing the most likely cause, its estimated probability and a “Why this diagnosis?” section comparing each reading with its expected value.
Real cases

Ask like a technician

From a symptom or from your readings, KCE pinpoints the most likely cause and lists the checks to run.

Case 1

Symptom

Low suction pressure

KCE diagnosis

Possible refrigerant shortage.

Check

  • Sight glass
  • Superheat
  • Possible leaks
Case 2

Symptom

High subcooling

KCE diagnosis

Possible refrigerant overcharge.

Verify

  • System charge
  • Condensing pressure
  • Condenser condition
Case 3

Symptom

Frozen evaporator

KCE diagnosis

Possible causes:

  • Insufficient airflow
  • Faulty fans
  • Ineffective defrost
  • Badly set expansion valve
