Forced Draft Cooling Tower Repair by EKG M&E Sdn Bhd

In the high-density urban areas of Kuala Lumpur and Selangor, forced draft cooling towers are frequently used in basements, plant rooms, or areas with high static pressure requirements. Unlike induced draft towers, the fans in a forced draft system are located at the base or side, pushing air into the tower. This design protects the mechanical "Drive Train" from the hot, humid discharge air, but it also makes the system vulnerable to specific moisture-related failures and "Air Choking."

EKG M&E Sdn Bhd specializes in Forced Draft Cooling Tower Repair, ensuring your centrifugal or axial blowers are mechanically sound and your heat rejection remains consistent.

1. Specialized Mechanical Drive Repairs

As an HVAC and Clean Air Specialist, we focus on the unique configuration of forced draft systems, which often utilize centrifugal blowers or side-mounted axial fans.

• Blower and Shaft Overhaul: Forced draft towers often use long shafts with multiple bearings. We perform Precision Bearing Replacement and shaft straightening to eliminate the "Whip" that causes casing vibration.

• Corrosion Protection for Fan Housings: Because the fan is at the bottom, it is susceptible to "Basin Splash" and chemical corrosion. We repair rusted fan scrolls and apply industrial-grade epoxy coatings to prevent metal thinning.

• Belt and Pulley Alignment: Many forced draft units are belt-driven. We use Laser Alignment to ensure the motor and blower pulleys are perfectly co-linear, preventing the "Belt Slip" that reduces airflow and wastes energy.

2. Airflow and Internal Component Restoration

Because the air is "pushed" in, any internal resistance can significantly drop the tower's performance.

• Infill and Drift Eliminator Cleaning: Scale buildup on the Infill creates "Back Pressure" that the forced draft fan must fight against. We perform deep descaling to lower the static pressure, allowing the fan to move more air for less power.

• Air Intake Screen Repair: The intake at the base of the tower is a magnet for city debris and leaves in KL. We replace damaged screens to prevent foreign objects from damaging the blower blades.

• VFD Tuning and Integration: We calibrate the Variable Frequency Drive (VFD) to match the unique static pressure curve of forced draft fans. This prevents "Stall" conditions and ensures smooth ramping during peak afternoon heat.

3. Structural and Basin Integrity

• Basin Leak Repair: Forced draft towers often have pressurized lower sections. We use FRP (Fiber Reinforced Plastic) lining to seal leaks in the cold water basin, preventing water damage to your plant room floor.

• Silencer and Attenuator Service: Because these towers are often located near occupied spaces, they use sound attenuators. We repair and clean these baffles to ensure noise compliance without restricting ventilation.
