Temperature Controller Repair

The controller is the brain of the cold room. Sensor drift, relay failure or programming errors cause silent temperature excursions. We calibrate, repair or upgrade controllers.

Cold Room Not Cooling
FLT_001

Cold Room Not Cooling

Temperature rising above setpoint — the cold chain is compromised. Rapid diagnosis of airflow, refrigerant charge and control logic is required to restore the thermal envelope.

Compressor Repair
FLT_002

Compressor Repair

The compressor is the heart of the refrigeration circuit. Failure halts all cooling. We diagnose electrical, mechanical and refrigerant-side faults before committing to repair or replacement.

Gas Leak Repair
FLT_003

Gas Leak Repair

Refrigerant leaks degrade performance and risk environmental damage. Electronic leak detection, nitrogen pressure testing and certified brazing restore system integrity.

Regassing
FLT_004

Regassing

Accurate refrigerant charging by weighed charge, not guesswork. We recover, vacuum and recharge to manufacturer specification to restore rated capacity and efficiency.
