Primarily, closed expansion tanks are a safety feature for systems in which water is used as a heat transfer medium to transfer the energy from heating and/or cooling to a living or utility space.

We, at Spirotech design, manufacture and distribute products and solutions which are key in securing your comfort in heating and cooling, while being energy-efficient and cost-effective.

The expansion system is a more complex system and offers greater accuracy in regulating the pressure in the system. This makes the system ideally suited for larger and more complex heating or cooling systems.

A standard expansion vessel consists of two chambers separated by a (fized) membrane. The system water is on one side of the membrane and gas with a predetermined pre-pressure is on the other side. A disadvantage of such an expansion vessel is that the system water is in contact with the inside of the vessel and corrosion can therefore occur, which can damage the installation.

The SpiroExpand range consists of hundreds of (expansion) vessels, expansion machines and accessories. From the most complex systems to simple solutions, there is a suitable SpiroExpand solution for every size of heating and cooling installation.

With Spirotech expansion vessels this is not an ordinary membrane but a balloon-shaped membrane, which enclosed the system water completely. This prevents the system water from coming into contact with the sheet steel wall of the vessel, thus preventing corrosion.

As the leading expert in system water quality, we developed reliable standard and customized solutions to boost performance and protect investments by helping save energy, increase comfort, reduce wear and tear and maximizing the uptime of your HVAC system.

Suboptimal pressure build-up in an installation has negative consequences for the performance and lifespan of the complete system. It is therefore essential to invest in a high quality pressure maintenance system tailored to the needs of your heating or cooling to ensure optimal pressure in the installation.

Combi boiler

Our EVN expansion vessels, with a volume of 4l to 140l, have a fixed pre-pressure with a bag membrane. This membrane ensures that the system water and the inner wall of the expansion vessel do not come into contact with each other, thus preventing corrosion (fromation of rust).

An optimal system pressure will keep system components functioning optimally and ensure trouble-free, cost-effective performance.

The system is designed to keep the pressure in the system constant, regardless of temperature fluctuations, and ensures safe and efficient operation of the heating or cooling system.

Spirotech an expert and market leader in the field of system water quality in heating and cooling systems. Our products have been prescribed for many years by international boiler and heat pump manufacturers, installers and consultants in residential and non-residential projects.

The pocket membrane serves to absorb the volume change of the system water when heated. The pre-pressure in the gas space of the expansion vessel pushes the system water back into the installation as it cools.

For larger and more complex heating or cooling systems with large pressure differences, it is advisable to use an expansion system, also known as a pressure maintenance system, to regulate the pressure. The main difference between the two is that an expansion vessel is a separate part of the system, while an expansion system is a complete system that includes multiple components.
