Pump-controlled pressure stabilization system VARIOMAT - basic tank VG 300, light gray 8600111

Pressure stabilization system VARIOMAT – a reliable solution for demanding installations

The VARIOMAT pump-controlled pressure stabilization system, in its basic VG 300 version, is a component dedicated to maintaining optimal pressure in heating, solar and cooling systems. This is an advanced solution that automates the stabilization process, eliminating problems related to pressure fluctuations resulting from changes in the heating medium temperature. This ensures the installation operates more efficiently and safely.

Construction and application

VARIOMAT tanks (basic VG or battery VF versions) are designed to operate in closed systems where temperature changes cause changes in water volume. This system compensates for these changes, maintaining a constant working pressure. Unlike traditional diaphragm tanks, VARIOMAT offers greater precision and efficiency thanks to the use of a pump controlled by a dedicated unit. Additionally, this system has a degassing function and automatically replenishes water losses in the installation – which translates to a longer system life and minimizes the need for service interventions.

Advantages and benefits

• Automatic pressure stabilization: Ensures constant working pressure in the installation, regardless of temperature changes and load. This translates to more efficient operation of heating devices and user comfort.
• Degassing function: Removes air from the installation, preventing corrosion and improving heat exchange efficiency.
• Automatic replenishment of losses: Maintains the appropriate water level in the installation, eliminating the risk of failure due to insufficient pressure.
• Efficient use of tank capacity: Compact design allows for saving space in the boiler room or technical room.
• Compliance with standards: Tanks are approved in accordance with the pressure equipment directive 2014/68/EU and equipped with an exchangeable membrane compliant with PN-EN 13831 – which guarantees safety and reliability.
• Versatile application: Ideal for heating, solar, cooling systems and pressure boosting installations.

For installers, this means easier installation and configuration of the pressure stabilization system and a lower risk of operational problems reported by end users. For end users, this guarantees thermal comfort and energy savings thanks to the optimal operation of the heating installation.
