SpillPress units are pressurisation sets that have been designed for applications where the final working pressure of the system must be similar to the cold fill pressure. This makes them ideal for older systems, high rise systems, large volume systems as well as higher temperature systems.
The SpillPress range has been designed for use on larger systems and tall buildings or where there is a need to limit the maximum working pressure.
The compactness of the units may also be a great advantage where the available floor space is limited. All SpillPress units are designed to give a compact solution to the control of expansion in larger heating/chilled water systems with a closed lid atmospheric tank to accept the system expansion and re-fill the system upon contraction.
The twin pump design operates duty/standby and the triple pump packages is designed to operate duty/assist/standby with auto-change over on pump run and elimination of a pump from the cycle on pump trip.
Smaller sets are typically fitted with a solenoid type spill valve whilst larger sets are supplied with one or more high quality self acting spill valves. The self acting valves allow excess pressure to be relieved back into the tank even in the event of a power failure.
A full digital control panel is fitted to the unit which gives an audible and visual alarm indication with mute, password protection and hours run log and has volt free contacts for BMS connection.
The SpillPress tanks are manufactured from high temperature GRP or Stainless Steel and are designed to accept the full expansion of the system, level control is fitted as standard. All tanks have an overflow and spill over weir to give a category 5 type AB air gap.
All SpillPress units are fully factory tested before dispatch.
Ranges
Smedegaard offer SpillPress in three configurations.
Compact
The 'Compact' range consists of the pump and control module mounted together with the spill tank on a common base plate. Peripheral turbine pumps in twin configuration are normally used in the range. However, other pumps can also be offered to suit specific requirements. The spill tanks are available in three sizes to accept 400 litres, 600 litres or 1000 litres of expansion. Solenoid valves are utilised as spill valves on this range.
Modular
The 'Modular' range consists of the pump and control module on a common baseplate and the spill tank supplied loose. Usually two vertical multistage pumps are fitted but, there is the option for a third pump. Self acting spill valves are utilised with this range but solenoid valves can also be fitted to this range. 'Modular' packages can accept expansion of up to 11875 litres and is suitable for use with boilers of up to 12000 kW at 90°C.
Bespoke
The 'Bespoke' range is designed and engineered for larger projects which exceed the capability of both the 'Compact' and 'Modular' packages. The 'Bespoke' sets are designed and built to the clients specific specifications with the aid of our in house expertise.
