Pressure boosting is increasingly used in a range of applications in HVAC&R. The application of appropriate pump sets and ancillary devices will be determined by the type of application in commercial and industrial developments.

These can range from open systems – such as the supply of potable water, hot water, fire protection systems and
condenser water systems – through to closed systems – such as heating systems (low, medium and high pressure) and chilled water distribution. 

If you have a building of more than two storeys or have a reduced / fluctuating mains water pressure you may need a booster set. If you have a private water supply (borehole) that discharges water into a reservoir or header tank for onward transport you may need a booster set.

As system water is drawn off, the pressure within the hydro - pneumatic accumulator will decrease. This accumulator contains a small amount of pressurised water to meet limited demand from the system. Should the
demand continue the pressure within the accumulator will decrease until such time
as the pre-set cut in point is reached when the lead pump will be automatically started.

This pump will continue to operate until such time as the system demand has ceased and pressure within the hydro - pneumatic accumulator has been re - established when, the pressure switch will operate the pump run on timer. This method of control will exclude pump hunting and the need for large vessels.
