Spillback SB Series of Pressurisation Units

PED compliant pressurisation units designed to maintain the water pressure in heating and chilled water systems for medium commercial situations



Our Spillback SB Series of PED compliant pressurisation units are designed to maintain the water pressure in heating and chilled water systems for commercial situations. They maintain a minimum set pressure in the system and are fully packaged with a stainless steel water tank included.

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.

The series offers options to deal with systems of temperatures of 3°C to 200°C (with buffer vessel), a fill pressure of up to 8.0bar and a system content of 50,000 litres of water. All with twin pumps and a building management signals package. Floor standing, they have been designed ergonomically so there is no need to kneel when checking the controls. Built to last and run quietly and efficiently to minimize heat loss and save energy, they also easy to service and maintain.

The stainless steel tank is atmospheric for low maintenance and the controls will identify leakages and allow for the circulating pumps to stabilize.

The stainless steel tank offers serious benefits.

Available Option:

We can supply a blanket in the tank to minimize evaporation losses and oxygen ingress.

High temperature handling.
