AC Plant Servicing & Overhauling
We specialize in the maintenance of high-capacity marine chillers and direct expansion (DX) systems from leading brands like Carrier, Daikin, and Sabroe.
- Compressor Overhauling: Complete teardown and rebuild of reciprocating and screw compressors, including replacement of pistons, liners, and shaft seals.
- Condenser & Evaporator Maintenance: Chemical descaling of seawater-cooled condensers to restore heat transfer efficiency, and cleaning of evaporator coils to improve airflow.
- Leak Detection & Gas Recharging: High-sensitivity F-gas leak testing and vacuuming/recharging of refrigerants (R134a, R404a, etc.) to ensure a closed, efficient circuit.
- Air Handling Unit (AHU) Care: Servicing of centrifugal blowers, replacement of marine particulate filters, and disinfecting ductwork to ensure air quality.

AC And ITS Controls
Advanced Control System Troubleshooting
A mechanical overhaul is only effective if the controls are precise. We diagnose the "brain" of your AC plant to prevent short-cycling and erratic behavior.
- PLC & Automation Repair: Troubleshooting PLC-based control panels, HMI displays, and SCADA integrations for centralized plant monitoring.
- Safety Interlocks & Alarms: Calibration and testing of HP/LP cut-outs, oil pressure safety switches, and freeze-up protection.
- Thermostat & Sensor Calibration: Verifying accuracy of temperature sensors and calibrating electronic expansion valves (EEV) for precise cooling.
- Electrical Logic Rectification: Repairing PCBs, replacing faulty relays, and ensuring stable power supply to motors to avoid vibration-induced electrical failures.
