Pump-controlled pressure stabilization system VARIOMAT - basic tank VG 800, light gray 8600511

Pressure stabilization system VARIOMAT – a reliable solution for demanding installations

The VARIOMAT pump-controlled pressure stabilization system is an advanced solution designed to maintain optimal pressure in heating, solar, and cooling systems. Based on the VG 800 base tank, this system provides precise control and compensation for changes in the volume of the heating medium resulting from temperature fluctuations. This ensures stable and efficient operation of the installation, while minimizing the risk of failure.

Design and application

The VG 800 tank is the basic element of the VARIOMAT system. Its design based on an interchangeable membrane, compliant with PN-EN 13831, guarantees reliable operation and long service life. This tank is approved for operation in accordance with Directive 2014/68/EU regarding pressure equipment, confirming its safety and high manufacturing quality. The possibility of coupling (series/cascade connection) allows the system capacity to be adapted to the individual needs of the installation.

VARIOMAT systems are an extension of traditional expansion vessels, offering automatic operation and constant control over the installation. Unlike standard vessels, which require manual adjustment, the VARIOMAT system automatically compensates for pressure changes, saving time and ensuring user comfort. Additionally, this system is characterized by efficient use of tank capacity, which translates into space savings.

Advantages and benefits

• Automatic pressure stabilization: The VARIOMAT system precisely maintains constant pressure in the installation, eliminating the risk of pressure surges and drops.
• Replaceable membrane: Ensures long-lasting and reliable operation of the device and easy servicing.
• Expandability: The coupling function allows increasing the system capacity if necessary.
• Wide temperature range: The maximum medium temperature (continuous) is 70°C, allowing the system to be used in various types of installations.
• Safety: Compliance with Directive 2014/68/EU guarantees safe use of the device.
• Compensation for volume changes: Effectively eliminates the impact of temperature changes on pressure in the installation.
• Degassing and make-up: Additional function in VARIOMAT systems ensures optimal operating conditions for the installation.

Technical parameters

The VG 800 base tank has a capacity of 800 liters and dimensions of 740 mm diameter and 2275 mm height. The maximum working pressure is 6 bar, and the nominal diameter of the connection for expansion is 1 inch (25). Thanks to these parameters, the tank is perfect for various heating and solar applications.
