Cooling Tower Services
We offer comprehensive cooling tower design, supply, installation, and maintenance services. Our expertise includes CTI-certified performance testing, component replacement, and retrofitting for industrial and commercial applications. With access to SPX Marley's full product range, we deliver engineered solutions for open/closed circuit, hybrid, and field-erected towers. Our team ensures compliance with AS 3666.1-2011 standards while minimizing water loss and noise through advanced eliminator technology.
Pump Sales & Service
Our pump division provides centrifugal pumpsets, pipework installation, and repair services for HVAC, industrial cooling, and fuel transfer systems. We specialize in laser alignment to
Laser Alignment
We deliver sub-millimeter precision laser alignment for rotating equipment including pumpsets, long shafts (up to 4.5m), and gearbox systems. Our services reduce vibration-related failures by maintaining coupling tolerances, with detailed reports documenting pre/post-alignment conditions. This prevents premature bearing/seal failures while extending equipment lifecycle in industrial and defence applications.
Defence Engineering
We provide specialized engineering services for Australian Defence Force bases, including fuel system maintenance, compressed air systems, and emergency generator servicing. Our team holds hazardous area certifications and follows strict compliance protocols for fuel tank inspections, pipeline maintenance, and environmental monitoring to meet defence operational requirements.
Facilities Maintenance
Our maintenance division offers planned and reactive services for pumps, valves, compressors, and fuelling systems. Using MEX maintenance planning software, we ensure compliance with Australian standards through scheduled inspections, electronic reporting, and rapid response call-outs for critical infrastructure across industrial, commercial, and defence sectors.
