Cooling tower fans,
drives and components.
LAICHAU has manufactured cooling tower fans, belt drives, gearboxes and components in Guangzhou since 1993. 18,600 m² plant, 1–6 m fan diameters, OEM and project supply.
LAICHAU · GUANGZHOUA component maker, not a trading desk.
Guangdong Lizhou Technology Development Co., Ltd. is the company behind the LAICHAU brand. The brand has supplied the cooling tower industry from Guangzhou since 1993; the legal entity was established in 2017.
Our 18,600 m² plant houses a research center, CNC machining, laser cutting, bending and assembly. We make the fan, the drive and the interface parts, then match them as one rotating assembly.
Fans, drives and the parts between.
Six product families, one matched rotating assembly. Select the duty point and we confirm the fan, blade angle and drive package.

Where the fans run.
Different duties need different materials, noise limits and drive packages.
HVAC & central cooling
Rooftop and plant-room towers for commercial, public and healthcare buildings. Noise, efficiency and delivery time all matter.
Data centers
Continuous duty and low noise. The ultra-low-noise series is designed for noise-sensitive data centre campuses.
Power & metallurgy
Large industrial towers and baseload projects with high airflow, long operating hours and a focus on fan life and spares.
Chemical processing
Corrosive water and air, chemical splash. Select 201 or 304 against chloride concentration and water chemistry.
District cooling
Central plants serving multiple buildings. Fans and drives must be predictable in noise and easy to maintain.
Coastal & corrosive sites
Salt air and high humidity. Stainless blades and multi-layer coating reduce corrosion and maintenance.
Documented, measured, repeatable.
Quality starts with the material certificate and ends with a balanced, documented fan.
Incoming material
Alloy grade, profile wall thickness and mechanical properties verified before production.
In-process control
CNC machining, blade-root fit, hub assembly and welding checked stage by stage.
100% dynamic balance
Every fan is balanced before shipment; ultra-low-noise models to G6.3.
Final verification
Airflow, static pressure, noise and interface dimensions checked against the approved data sheet.
From the factory floor.
