Three locations in Thailand
- Bangkok head office — 22/44 H-Cape Biz Sector, Sukhaphiban 2 Rd., Prawet, Prawet District, Bangkok 10250
- Rayong workshop — 888/10, Moo 2, Phana Nikhom, Nikhom Phatthana, Rayong 21180
- Khon Kaen workshop — 371, Bueng Niam, Mueang Khon Kaen, Khon Kaen 40000
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.
Quality and professional membership
Our credentials state what clients can verify: the quality-management certification held by Synergy Services and the professional institute whose procedures guide our performance testing.
Our Commitment to Quality
With 20 years of experience, we are a member of the Cooling Technology Institute (CTI), which advocates and promotes the use of environmentally responsible evaporative heat transfer systems and cooling towers. Our performance testing follows CTI procedures, and we supply CTI-certified products where a project calls for them. Additionally, our quality management system’s ability to meet customer and regulatory requirements is proven by ISO 9001 certification — certificate 9940, issued by Peers Quality Assurance Ltd under UKAS accreditation. CTI’s member directory is public and lists Synergy Services Co., Ltd.

Three cooling tower product groups
Mechanical Parts — gearbox or gear, fan assembly, and drive shaft.
Static Parts — fill or fill media, drift eliminator, and nozzle.
Structure and Accessories — FRP structure and accessories for repair, replacement, upgrade, and reconstruction.
Mechanical Parts
Mechanical drive components
Gearbox or Gear
Transfers motor power to the fan at the required speed and torque; selection is matched to duty, ratio, mounting, shaft arrangement and operating environment.
Fan Assembly
Hub, blades and related hardware move air through the tower; support includes inspection, balancing, pitch and tip-clearance setup, replacement and commissioning.
Drive Shaft
Transmits power between motor and gearbox; supply and installation can include couplings, alignment and vibration checks.
Static Parts
Water and air contact components
Fill or Fill Media
Creates the contact surface for heat exchange between circulating water and air; film, splash and other configurations suit different tower, water and fouling conditions.
Drift Eliminator
Captures water droplets carried by leaving air; selection considers airflow, pressure drop, drift-loss requirement, material and support arrangement.
Nozzle
Distributes circulating water across the fill; pattern, flow, pressure, connection and material are matched to the required coverage.
Structure and Accessories
FRP support and access scope
Frame and bracing
Columns, beams and braces form the tower's structural support system.
Component supports
Internal supports carry casing and cooling-tower components.
Maintenance access
Platforms, walkways, handrails and ladders provide access for inspection and service.
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.
Inspection and performance testing
Cooling tower performance testing in Thailand (CTI ATC-105): we measure range, approach and airflow to find lost capacity.
- Cooling tower thermal performance evaluation (CTI-standard)
- Airflow and fan performance analysis
- Water distribution uniformity check
- Vibration analysis on rotating equipment
Overhaul and maintenance
Cooling tower gearbox, drive-shaft and fan overhaul in Thailand — the documented repair sequence, real findings, and what you receive at handover.
- Scheduled inspections aligned to your plant’s planned shutdown calendar
- Gearbox and motor overhaul
- Fan blade replacement and rebalancing
- High-pressure cleaning of fill, basin, and distribution headers
Parts replacement
Cooling tower fill, drift eliminator and fan blade replacement in Thailand — a measured example of what recovered performance looks like, and typical payback.
- Fill replacement
- Drift eliminator replacement
- Fan blade replacement
- Bearings and oil seals
- Motor mounts, casing panels and basin liners
Upgrade and reconstruction
Cooling tower upgrade and reconstruction in Thailand — engineered retrofits and rebuilds, sized from a measured baseline, not a guess.
- Fan and drive system upgrade to variable frequency drives (VFD)
- Water distribution system redesign for improved uniformity
- Basin enlargement and additional cells
- Complete casing, basin, and fill replacement with modern materials (FRP or concrete)
New cooling towers
We design and build new cooling towers, install them on your site and test them at handover. Every tower is sized and quoted per project.
- FRP counterflow — air rises against the falling water and meets the coldest water on the way out, so the fill is used efficiently.
- FRP crossflow — air crosses the falling water horizontally, with gravity water distribution and fill you can reach from outside the cell.
- Concrete — chosen where decreased fire risk and, for larger structures, higher load-carrying capacity justify its higher first cost.
- Package — assembled at the factory and delivered in as few sections as transport allows, so there is less work on site.
