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 pressurization 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 - Pressurization 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.
