Stable pressure control for heating and cooling systems
The Varem UR25231CS000000 25L expansion vessel stabilises pressure in closed systems by compensating for water expansion caused by temperature changes.
Extravarem LR – durable and compact
With a fixed diaphragm and galvanised steel flange, this vessel is engineered for long-term operation. Its compact size (455 mm height, 288 mm diameter) makes it suitable for modern boiler rooms and heat pump installations.
Technical performance from the drawing
Page 1 confirms a 6 bar max operating pressure, 9 bar test pressure and a preset value of 1.5 bar. This ensures compatibility with contemporary heating and cooling circuits.
Easy installation using 3/4" connection
The 3/4" GAS ISO 228/1 connection allows quick integration into existing pipework. Suitable accessories can be found under connection materials.
Compatible with heating and cooling circuits
The medium specification “air + water” makes this vessel suitable for boilers, heat pumps and chilled-water systems. Pair it with components from heat pumps or buffer tanks for a complete installation.
