Variable Speed Drive (VSD) Chiller Pumps

Intelligent pumping for maximum efficiency.
A VSD on your chiller pump allows the motor speed to adjust to real-time cooling demand, slashing energy use and reducing wear. EKG Malaysia designs, supplies, and commissions VSD pump systems for both new installations and retrofit projects, ensuring seamless integration and reliable operation.

How It Works:
Instead of running at a fixed speed, the VSD (or VFD) modulates the pump's motor speed based on signals from pressure sensors or the building management system (BMS). This maintains the precise flow and pressure required, using only the energy necessary for the current load.

Key Benefits:

• Energy Savings – Reduces pump energy consumption by 30–50% or more at part load.

• Soft Start & Stop – Eliminates electrical inrush current and reduces mechanical stress on pumps and pipes.

• Precise Control – Maintains consistent system pressure, improving comfort and stability.

• Extended Equipment Life – Lower operating speeds reduce bearing and seal wear.

Ideal Applications:

• Chilled water and condenser water pumps

• Primary, secondary, and variable primary flow (VPF) systems

• Retrofits for constant-speed pumps in existing buildings

Why EKG?

• Expert Selection & Sizing – We match the VSD to your specific motor and control requirements.
