Minipack Basic Pressurisation Unit

Cost effective pressurisation unit designed to maintain the water pressure in heating or chilled water systems for small domestic and commercial situations



Our cost effective Minipack pressurisation unit is designed to maintain the water pressure in heating or chilled water systems for small domestic and commercial situations.

Their principle of operation is to accommodate the expanded water volume as the temperature rises and then refill the system as the temperature decreases and the pressure drops.

Wall (or floor) mounted, it can deal with systems of temperatures of 3 to 90°C, a fill pressure of 3.5bar and a system content of 5,000 litres of water.

Fitted with a single pump, simple controller providing a basic display and a volt free contact for the boiler cut-out in case of high pressure alarm.

Designed and built to last, it runs quietly and efficiently to save energy, with reliability giving you peace of mind.

The components are easily accessible for servicing and maintenance.
