The Intatec Cal-Pro 18 litre heating expansion vessel (Z1-301018) is supplied with a mounting bracket. In a closed heating system, water cannot be compressed, so any increase in water volume caused by a rise in temperature is absorbed by the expansion vessel.
Key Features:
– Suitable for closed (sealed) heating systems
– 18 litre capacity
– Carbon steel construction
– SBR synthetic rubber diaphragm
– Hard wearing epoxy polyester powder coated finish
– Maximum working temperature 90°C
– Maximum working pressure 4 bar, pre-charge 2 bar
We recommend this vessel is fitted by a qualified heating installer.
