Optimize energy use and simplify your chiller plant.
VPF systems use a single set of variable-speed pumps to serve both chillers and building loads, eliminating the need for separate primary/secondary loops. This streamlined design reduces installation cost, saves pump energy, and improves part-load efficiency—ideal for modern buildings with variable-flow chillers.
How It Works:
A single pump loop varies flow based on real-time cooling demand. Specialized controls and valves ensure chillers always receive their minimum required flow, protecting equipment while allowing the system to adapt efficiently.
Key Benefits:
Lower energy use – Pumps slow down at part load, cutting power consumption significantly.
Reduced complexity – Fewer pumps, pipes, and valves compared to primary-secondary systems.
Space savings – Compact design frees up mechanical room space.
Improved control – Modern sequences allow seamless chiller and pump staging.
Why It Works for Malaysia:
Matches the part-load profile of tropical buildings.
Supports GBI/Green Building certification with measurable energy savings.
Compatible with today’s variable-speed chillers and intelligent BMS integration.
