Aquatech upgrades pressurisation units

Aquatech has upgraded its successful Aquapress MS41 and MS51 system pressurisation units with the addition of micro-processor control with accurate transducer for measuring system pressure. This method of operation replaces pressure-switch control and is more user friendly and requires less maintenance. These units are designed to maintain a set minimum pressure in sealed heating or chilled-water systems. They provide a fluid category 5, back-pressure and siphonage as required by the Water Supply (Water Fittings) Regulations of 1999. They have a single pump and are mounted on the wall. The MP41 is for systems of up to 3000 l or 300 kW. The MP51 is for systems of up to 6000 l or 600 kW. Both have a maximum operating temperature of 90°C. Once the system has been filled, the Aquapress unit operates automatically to restore pressure if it falls below the required level. If the pressure is too high or too low, the operation of the boiler or chiller can be interrupted via the volt-free contact provided.
