Did you know that switching from a valve-based system to distributed pumps can save energy significantly?
Most chilled water systems use large centralised pumps and chillers controlled by valves. These valves waste loads of energy and make it difficult and time-consuming to balance the system correctly. Distributed Pumping systems for commercial buildings is a paradigm shift towards decentralised pumps that can save energy significantly and create a more consistent, comfortable climate throughout the building.
54% energy savings
Grundfos Distributed Pumping helped Ngee Ann, a large university building in Singapore, increase Delta T by 28% and reduce total pump energy by 54% – all while providing optimal comfort for building users.

How decentralised pumping saves energy
Distributed Pumping solutions replace centralised pumps and energy-consuming balancing and control valves with intelligent pumps placed on each floor of the building. This means the new system is equipped with components that generate pressure only when and where needed. The result is substantial energy savings and a more comfortable indoor climate.
Inadequate commissioning leads to poorly balanced systems and excessive energy use. Replacing valves with pumps ensures optimal pressure and flow to each terminal unit at all times. So, you can increase comfort and improve Delta T. Get a great introduction to how Grundfos Distributed Pumping works in this video.

Distributed pumping can be applied to existing chilled water systems that need retrofitting or to new commercial buildings planned with chilled water air conditioning. It can also be applied in decentralised chilled water systems. Dig into the technical details of these specific applications and more in our distributed pumping white paper.
Beyond total energy savings and improved comfort, Grundfos Distributed Pumping offers easy commissioning, easy integration and improved chiller performance. Get an overview of all the benefits of Distributed Pumping and compare our system to a traditional valve-based system in our brochure.
Distributed pumping systems consist of five key components: primary pumps, distributed pumps, primary pump controller, check valves and sensors located throughout the building. The primary pump controller uses a control algorithm to manage the primary pumps, which are variable speed pumps that are regulated by sensor measurements from the decoupled line to avoid over or under pumping the system.

The TPE3 works as a primary pump providing supply pressure for the primary side only. With intelligent technology that ensures better system control, TPE3 enables easy installation and commissioning of your system.
The Controller minimises the flow in the bypass line, prevents the primary pumps from over pumping and ensures that the flow for the chillers is always above their minimum constraints.
