Designing the optimal water boosting system

Your challenge:

To ensure constant pressure, tall commercial buildings or any buildings with the requirement for water delivered efficiently face two major challenges. First, pre-pressure in water mains is rarely high enough to cover the whole building. Second, water demand changes constantly. Break tanks are typically installed to keep water on stock. However, this makes the need for pumps even more urgent as water needs to be boosted to reach different users.

This means a booster system must not only be reliable but also have the intelligence to maintain the right pressure regardless of consumption. Single booster systems, however, can result in unacceptably high pressure within the lower floors. When this happens the system needs expensive pressure relief valves that waste energy to remove excessive pressure.

Our solution:

Choosing the right pressure system depends on the height of the building and the load profile. But in most cases a zone divided system, where a number of boosters serve their own pressure zone, offers the most efficient solution. Zone divided boosters ensure no more pressure is added to the system than what is needed.

This means your building has equal water pressure to all floors without wasting energy – even under fluctuating consumption. A zone divided approach also offers the reliability of multiple pumps and ensures the system can adapt to fluctuating consumption.

Reduce energy consumption by 55% by selecting the correct Booster System for your application.
