## Summary description

Comap Contra-Flex expansion vessel for central heating systems, 200 L capacity with 1.5 bar precharge and 6 bar maximum pressure rating. Red, with 1" connection for hydraulic systems. Designed to accommodate thermal expansion, reduce pressure fluctuations and protect boilers, pumps and piping in residential or light-commercial heating installations.

## Long description

The Comap Contra-Flex expansion vessel 200 L with a 1" connection is a diaphragm-type pressure vessel intended for central heating systems. It comes precharged to 1.5 bar and is designed to withstand system pressures up to 6 bar. The red-painted steel shell and internal elastomer membrane separate the system water from a compressed air cushion, allowing the vessel to absorb thermal expansion and reduce pressure variations in residential and light-commercial installations.
Advantages
This expansion vessel provides a large 200-litre capacity that reduces the frequency of pressure relief valve activation in heating circuits. The precharge at 1.5 bar simplifies commissioning when used in typical domestic systems, and the 6-bar maximum rating offers a safety margin for higher-pressure applications. A 1" hydraulic connection ensures compatibility with common piping arrangements, while the diaphragm design minimizes waterlogging and extends service life under normal operating conditions.
Suitable for
Domestic central heating systems with closed-loop circuits
Light-commercial heating installations requiring a 200 L expansion volume
Systems with a 1" hydraulic connection and up to 6 bar operating pressure
Applications where thermal expansion needs to be controlled to protect boilers, pumps and piping
When it may not be suitable
This vessel may not be suitable for open systems or installations that require potable-water direct contact, since it is designed for closed heating circuits. It is not appropriate where the system pressure exceeds the 6 bar rating or where a different precharge pressure and vessel volume are specifically required for hydraulic balance.
Key specifications
Type: Diaphragm expansion vessel
Nominal capacity: 200 litres
Precharge pressure: 1.5 bar
Maximum allowable pressure: 6 bar
Connection size: 1" (inch)
Colour: Red (painted outer shell)
How to use
Install the expansion vessel on a stable support or bracket close to the heating system return line, using the 1" connection to integrate it into the hydraulic circuit. Before final commissioning, verify and, if necessary, adjust the precharge pressure with the vessel isolated from the system and the membrane at ambient temperature. After connection, bleed air from the heating circuit and monitor system pressure during the first heat-up cycle to ensure correct operation. Periodic inspections should include checking the external shell for corrosion, verifying the precharge pressure and ensuring the connection fittings are leak-free.
What to consider before purchase
Confirm your system is a closed heating circuit compatible with a diaphragm expansion vessel
Ensure the nominal 200 L capacity and 1.5 bar precharge meet your calculated expansion needs
Verify that system maximum pressure does not exceed 6 bar
Check that a 1" connection matches your piping or adaptor requirements
Usage recommendations
For reliable operation, mount the vessel in an accessible position for periodic checks, set the precharge when the vessel is removed from the system and cold, and schedule routine inspections to verify membrane integrity and connection tightness. When replacing an existing vessel, compare volumes and precharge values to maintain correct hydraulic balance.
