Most issues within HVAC systems are closely related to air being introduced into the system as a result of pressurization issues. A poorly designed, installed or maintained pressurisation system can lead to negative pressures around the circuit. Air is drawn in through automatic air vents, gaskets and micro leaks and water may be emitted through pressure relief valves, leading to frequent refilling. The introduction of oxygen through leaks or by refilling with undegassed, mostly hard water also makes corrosion inhibitors significantly less effective.

SpiroPress - Pressurisation assortment

Increase the performance for the entire lifetime

SpiroPress covers a full range of solutions, from the most basic setup to the most extended, complicated system. All units are used to provide full 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. SpiroPress can dramatically increase performance and avoid premature failure of major system components.

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

Using a pressurization unit means optimized pressure in your system
and saving space in your boiler room!

SpiroPress Expansion Tanks

Expansion vessels

These are ‘passive’ pressure management systems. A preset gas pressure in the membrane expansion vessel is used for pressure control. Because membrane expansion vessels do not have a make-up function, we ideally combine this type of pressure control with a vacuum degasser including a make-up function.

The expansion tanks are available in 12 configurations and with volumes between 2 -3000 litre and an operational pressure range from 3.0 – 25 bar.
