DRESSER-RAND Product Lines We Repair
Our engineers are trained on the full DRESSER-RAND product range. Below are the major product families we service.
Dresser-Rand Centrifugal Compressor Control Systems
Control and monitoring systems for centrifugal compressors including inlet guide vane (IGV) control, surge prevention, and capacity management. Common issues include solenoid valve failures, pressure transducer errors, and controller calibration drift affecting compression efficiency.
Dresser-Rand Reciprocating Compressor Electronics
Valve unloading controls, pressure relief systems, and inter-stage management for reciprocating compressors. Failures often manifest as gas by-pass issues, stuck unloaders, or erratic pressure regulation requiring specialized diagnostic capability.
Dresser-Rand Anti-Surge and Blow-Off Systems
Anti-surge valve controllers and blow-off protection for preventing compressor surge and protecting equipment. Typical faults include slow surge response, stuck blow-off solenoids, and feedback sensor malfunction causing capacity loss.
Dresser-Rand Turbine and Expander Controls
Control systems for Dresser-Rand turbine-expanders and waste heat recovery units. Repair focus includes speed control loops, bearing temperature monitoring, and vibration detection modules commonly found in LNG and refinery applications.
Dresser-Rand Inlet Temperature and Pressure Modules
Instrumentation and control modules managing inlet conditions for compressor optimization. Common failures include calibration loss on temperature transmitters, pressure sensor drift, and failed signal conditioning cards affecting control stability.

Common DRESSER-RAND Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DRESSER-RAND equipment arriving at our workshop.
- ✓Inlet Guide Vane (IGV) position sensor malfunction — Dresser-Rand IGV systems rely on LVDT position sensors exposed to compressor inlet temperature and moisture. Sensor drift or intermittent signal is common after 5-10 years of operation, causing loss of capacity control feedback and surge risk.
- ✓Anti-surge controller slow or no response — Dresser-Rand anti-surge modules monitor discharge pressure through analog input cards that degrade over time. Sluggish response indicates analog signal conditioning failure or controller processor lag, risking compressor surge and mechanical damage.
- ✓Unloading valve stuck or erratic operation — Dresser-Rand reciprocating compressor unload solenoids accumulate carbon deposits and mechanical wear from cycling over years. Stuck or oscillating unloaders prevent full gas by-pass, causing excess energy consumption and heat generation.
- ✓Temperature sensor reading errors and control instability — Dresser-Rand temperature transmitters installed in high-vibration compressor inlet environments suffer connector corrosion and internal RTD element failure. Erratic readings trigger false alarms and disrupt compressor inlet temperature control loops.
- ✓Pressure relief or blow-off system latching failure — Dresser-Rand blow-off and relief valve solenoids experience coil burnout or mechanical sticking when subjected to repeated high-pressure spikes. Failed latching prevents safe emergency gas venting and risks equipment overpressure.
- ✓Turbine speed control loop instability and hunting — Dresser-Rand turbine-expander speed control loops drift due to tachometer sensor misalignment or PID tuning parameters shifting over time. Hunting behavior causes vibration, bearing stress, and reduced turbine efficiency in LNG and recovery applications.
