FLT_001 // DIAGNOSTIC_PROTOCOL

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.

Defrost Fault
FLT_005

Defrost Fault

Failed defrost cycles allow ice to choke the evaporator, collapsing airflow. We repair heaters, sensors, timers and defrost termination logic to keep the coil clear.
