Our Services

Heating, solar and cooling water systems (Reflex)
Diaphragm-type pressure expansion vessels in the Reflex range are suitable for a wide variety of pressure ranges and nominal volumes.

Drinking and service water systems (Refix)
Diaphragm-type pressure expansion vessels from the Refix range are suitable for drinking water and service water systems.

Reflexomat, compressor-controlled
In Reflexomat pressure-maintaining stations, the pressure on the gas side of the vessel is regulated by a compressor.

Variomat, pump-controlled
In Variomat pressure-maintaining stations, the pressure is regulated by a pump in the hydraulic system.

Servitec,
Degassing
The Servitec product range offers reliable protection against gas-related issues in both small and large-scale systems – thanks to the active degassing of even dissolved gases.

Ex-separators, separation technology
Reflex separators are not only capable of venting, but also of separating microbubbles, dirt or sludge.

Fillcontrol top-up systems
Mit den Produkten der Fillcontrol-Serie ermöglicht Reflex eine kontrollierte, automatisierte Nachspeisung für alle gängigen Anlagenkonfigurationen.

Fillsoft Water Treatment Technology
Modern boilers and heat generators are required to deliver ever-increasing heat output and efficiency.
Inspection and maintenance of plant and pressure vessels
Pressure vessels can include diaphragm pressure expansion vessels, buffer tanks, sludge tanks, as well as heat exchangers or boilers. They pose a potential hazard, which is essentially determined by the pressure, volume, temperature and the medium itself. The manufacture, commissioning and operation of pressure vessels and complete systems are subject to specific requirements that are regulated by law.
You can read the guidelines on ‘Strength testing in accordance with the Industrial Safety Regulation’ for further information (German).
