BITZER Equipment We Repair — By Category
BITZER Product Lines We Repair
Our engineers are trained on the full BITZER product range. Below are the major product families we service.
BITZER Semi-Hermetic Reciprocating Compressors
BITZER 4H, 4F, 6H series reciprocating compressors with integrated electric motor windings. Common repair issues include motor burnout, high discharge temperatures, valve plate wear, and crankshaft seal failures leading to refrigerant leakage.
BITZER Semi-Hermetic Screw Compressors
BITZER CSH, CSV screw compressor range for medium and high-capacity applications. Typical failures include oil injection valve malfunction, capacity modulation solenoid faults, rotor bearing wear, and electronic expansion valve controller failures.
BITZER Electronic Expansion Valve (EEV) Controllers
BITZER EEV control modules for precision refrigerant metering in large commercial and industrial systems. Common faults include solenoid coil burnout, stepper motor position loss, thermistor sensor drift, and firmware lockup requiring reprogramming.
BITZER Crankcase Pressure Regulators (CPR) and Oil Management
BITZER OVX, FUX, and KVX series oil separation and pressure regulation components. Repair challenges include spring fatigue, diaphragm rupture, thermal expansion issues, and solenoid valve stiction in bypass circuits.
BITZER Compressor Protection and Monitoring Systems
BITZER SmartLink, ComLog, and Carly refrigeration monitoring systems. Common faults include relay card failure, temperature sensor malfunction, communication protocol loss, and backup battery degradation affecting alarm logging.
BITZER Capacity Control Valve Assemblies
BITZER CSLV and CSRV variable capacity control valves with integrated solenoid actuation. Typical repair needs include solenoid coil replacement, valve seat erosion from oil carryover, pilot line blockage, and slide rod sealing issues.

Common BITZER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BITZER equipment arriving at our workshop.
- ✓BITZER compressor motor winding insulation breakdown — Sustained high discharge temperatures (above 110C) degrade motor winding enamel. Inadequate oil circulation, refrigerant floodback, or running compressor with low suction pressure accelerates winding failure in 4H and 6H series.
- ✓BITZER EEV solenoid coil failure and valve stiction — Moisture ingress into solenoid coil, contaminated refrigerant causing coil oxidation, or sustained voltage spikes from lightning strike or drive relay chatter. Stiction occurs when mineral deposits accumulate on EEV needle seat under oil starvation.
- ✓BITZER expansion valve controller lockup and position loss — Stepper motor in DEK series controllers loses synchronisation when power is interrupted mid-stroke or when refrigerant condensation corrodes motor windings. Firmware crash from thermal stress or corrupted calibration table prevents position feedback.
- ✓BITZER compressor crankshaft seal leakage and oil weeping — Continuous high discharge temperature cycling causes metallic seal ring distortion. Contaminated oil with acids corrodes seal surfaces. Inadequate suction gas cooling and lack of oil backflush in start-up phase accelerate seal wear.
- ✓BITZER screw compressor rotor bearing wear and rotor rub — Oil starvation during high-capacity operation, dirty oil clogging bearing supply ports, or bearing material fatigue after 40000+ running hours. Rotor rubs against casing cause vibration, noise, and compressor seizure if unchecked.
- ✓BITZER capacity control valve solenoid chatter and erratic modulation — Worn valve seat allows pilot pressure bleed preventing stable solenoid engagement. Contaminated oil particles stick to armature face. Low system pressure or damp coil insulation in monsoon season causes intermittent activation.
