The KGN Pillinger electronic range of Pressurisation Units are fully automatic, PLC controlled and designed to maintain the required system pressure in both heating and chilled water systems.

Available with single or dual pumps, the units are housed in floor standing, wall mounting cabinets or on a purpose sized chassis. A Fill Spill Unit is available for larger systems.


The KGN Pillinger Range of Fill Spill units are designed for maintaining pressure on larger sealed systems capable of extreme temperature and pressure changes, and built with 304 stainless steel tanks for longevity.

They are available in bespoke design builds to fit within plant room constraints.


KGN Pillinger Expansion Vessels are ideal for containing expansion water in sealed heating, chilled water and HWS systems, and as accumulator vessels for pressure boosting systems.

The vessels contain a cylindrical flexible rubber diaphragm which forms the water space, preventing water contact with the steel shell. As the gas space surrounds the diaphragm, shell corrosion is eliminated.
