Varem UR035231CS000000 - Expansion Vessel (35L)

Reliable pressure compensation for closed heating systems

The Varem UR035231CS000000 35L expansion vessel ensures a stable pressure balance in closed heating and cooling systems by absorbing volume changes caused by temperature fluctuations.

Vertical design with fixed diaphragm

As part of the Maxivarem LR range, this vessel features a fixed diaphragm that keeps air and water separated. The galvanised steel flange adds rigidity and long-term durability.

Strong technical performance

According to the technical drawing, the vessel supports a 6 bar max operating pressure, 7.5 bar test pressure, and a preset of 1.5 bar. Its compact size (525 mm height, 320 mm diameter) makes it easy to integrate into plant rooms.

Compatible with heating, cooling and heat pump systems

The medium specification “air + water” makes it suitable for boiler systems, heat pumps and chilled water circuits. Combine this vessel with components from connection materials or heat pumps to build a complete installation.

Simple installation with 3/4" connection

The 3/4" GAS ISO 228/1 threaded connection shown in the drawing allows fast coupling with standard pipework. Ideal for both small and medium-sized residential or commercial systems.
