Reflex - DE 60 Pressure Vessel - 60Ltr

The Refix DE 60 diaphragm expansion vessel is designed for water supply installations that are not subject to DIN 1988 requirements, making it suitable for specialist systems such as fire extinguishing installations, service water systems, underfloor heating and heat source applications. Designed and manufactured in accordance with DIN EN 13831 and approved under Pressure Equipment Directive 2014/68/EC, this vessel is built for reliable pressure maintenance across demanding system environments.

The vessel features a butyl bladder in line with DIN EN 13831, with replaceable bladder construction from 50 Ltrs upwards. Parts in contact with water are corrosion-protected, while the durable epoxy resin coating supports long service life. It is also suitable for systems using antifreeze additives between 25% and 50%, making it a practical option for a wide range of closed-system applications.

The Refix DE 60 is finished in blue and supplied with adjustable feet. Pressure gauge and supply pressure valve protection is provided by a clip design on applicable variants, and the vessel is intended to deliver reliable and consistent performance in commercial and specialist water system installations.
