When should you use a pressurising unit?

Today’s highly energy-efficient heating and cooling systems offer optimal performance with air-free system water. Most issues within HVAC systems are closely related to air being introduced into the system as a result of pressurisation issues.

A poorly designed, installed or maintained pressurization system can lead to negative pressures within the circuit. The introduction of air through leaks or refilling the system with (calcareous) non-degassed tap water also makes corrosion inhibitors significantly less effective.

Prevent air intrusion in your system with a pressurization unit.

Increase performance with pressurisation

Our SpiroExpand solution enables automatic pressure monitoring, control, and provides degassed makeup water. Adding a pressurisation solution to our established degassing products makes it possible to provide a complete, integrated care solution for your system.

SpiroExpand can dramatically increase performance and avoid premature failure of major system components. Combine this together with dirt separation and degassing, it provides a system that performs the way it has been designed to.

Solutions that Impress

A poorly designed, installed and maintained pressurisation system can lead to negative pressures around the circuit. Air can be drawn in through Automatic Air Vents, gaskets and micro leaks. High pressure situations can lead to water being emitted through the safety valves and the subsequent frequent addition of further raw refill water.

Pressurisation, the key

The SpiroExpand - range

Our solutions for pressurization

SpiroExpand covers a full range of solutions, from the most basic setup to the most extended, complicated system. All units also provide additional vacuum degassing of the system water. Make-up water is degassed prior to system entry, offering substantial long-term protection. Not just for the commissioning phase, but for the entire lifetime of the system. SpiroExpand can dramatically increase performance and avoid premature failure of major system components.

Some of our SpiroExpand solutions are:

  • SpiroExpand PicoControl
  • SpiroExpand MultiControl Kompact
  • SpiroExpand Multicontrol Cool
  • SpiroExpand MultiControl Modular
  • SpiroExpand TopControl Modular
  • Expansion Vessels
