Pressurisation Units

Pressurisation Units

Pumps UK LTD's pressurisation units are designed to replace water that has been lost through system leakage and to maintain the system design fill pressure in sealed heating and chilled water systems. Most modern boiler and air conditioning systems are sealed and require a device to maintain the system pressure and give warnings when the fill pressure is low or when the water has over expanded causing a high pressure.

All sealed heating systems have to have an interlock circuit so that the boilers are cut out if the unit is at fault. Incorrect calibration of the unit settings or pre charging of the expansion vessels will cause the system to malfunction. Pumps UK Ltd are able to size, supply and commission units to suit most applications.
