35 CMR Expansion Vessel 1" WRAS

The Ibaiondo 35 CMR-P 35-liter expansion vessel is designed for installation in domestic hot water (DHW) systems, absorbing the volume variations that occur when water temperature increases.

This expansion vessel helps protect the installation against pressure increases caused by water expansion, contributing to the proper operation and safety of the domestic hot water circuit.

35-liter expansion vessel for domestic hot water

The Ibaiondo 35 CMR-P model has a nominal volume of 35 liters and is made of steel. Its vertical configuration includes legs for stable floor installation.

Inside, it incorporates a replaceable membrane in accordance with EN 13831 and suitable for potable water. As the membrane is replaceable, it can be changed when necessary without having to replace the entire vessel.

The water connection is made of stainless steel and features a 1-inch thread, providing a durable connection suitable for sanitary water installations.

The membrane complies with the requirements of EN 13831, while the stainless steel water connection helps make this model a particularly suitable solution for DHW circuits.

Designed for DHW installations

The Ibaiondo 35 CMR-P vessel is designed to operate at a maximum working pressure of 10 bar and withstand a test pressure of 15 bar. It is supplied with a factory air precharge of 3 bar, which should be checked and adjusted during commissioning when installation conditions require it.

Its operating temperature range is from -10 to 100 degrees Celsius, allowing use in domestic hot water installations within the limits established by the manufacturer.

Manufactured in accordance with European regulations

The Ibaiondo 35 CMR-P expansion vessel, reference 01035249, is manufactured in accordance with Directive 2014/68/EU on pressure equipment. It also features a white epoxy-painted exterior finish to protect the steel body.

An ideal solution for domestic, commercial, and professional installations that require a 35-liter DHW expansion vessel, 10 bar, and 1-inch connection, with a replaceable membrane and vertical configuration with legs.
