Two dedicated overhaul workshops

The Rayong and Khon Kaen sites are purpose-built overhaul workshops, not just service points. Rayong added a dedicated gearbox overhaul station in 2018; Khon Kaen opened with the same capability in 2026, extending overhaul coverage into Northeast Thailand. Three internal teams carry out the work each site produces — a Shutdown team, a Long Term team, and an Overhaul team — each with its own senior engineers, service engineers, supervisors, and foremen.

Four cooling tower service lines

Built for industrial uptime

  • 3 — Thailand locations
  • 2 — Overhaul workshops
  • 100+ — Approved vendor lists
Inspect → Repair → Verify

One engineering team connects condition assessment, workshop overhaul, component replacement and post-work checks.

Global manufacturing partners

Three cooling tower product groups

Service innovations

Beyond the four core service lines, we install and support three manufacturer programmes.

BAC’s Endura Drive is a direct-drive system for Series 3000 cooling towers that removes the gearbox and belt from the powertrain entirely. With no gear or belt to inspect, test, or replace, it lowers maintenance cost, and more than 500 units are installed worldwide.

CTP’s chemical cleaning lines address three parts of a plant: Neutrol® for offline cleaning of heater and boiler tubes during shutdowns, Neutramex® for online fireside cleaning of heaters and boilers on convection and radiant banks, and Decamex® for on-line or off-line air-side cleaning of air coolers and condensers without scaffolding or plenum entry. All three are biodegradable and non-hazardous. CTP also supplies mobile wastewater treatment — temporary, modular, fully automated systems for commissioning, shutdown, maintenance, and emergency projects that keep a plant in environmental compliance without extending downtime.
