Minipack Enhanced Pressurisation Unit

Enhanced version of Minipack-Basic with twin pump and microprocessor control for small domestic and commercial situations



The difference between this and the basic unit is that the enhanced version has a twin pump and an enhanced microprocessor control with full building management signals package.

Our Minipack enhanced, pressurisation unit is designed to maintain the water pressure in heating and 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 twin pumps and an enhanced microprocessor control with full building management signals package. Certified and 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.
