MST:  Carbon Steel Thermal Storage Vessels

The Adveco range of carbon steel thermal storage tanks have been carefully designed to serve a combined heating and hot water application, and feature a stainless steel coil for potable water heating as well as up to two additional coils for use with central heating systems.

The MST range features high and low level flow and return connections at 90° to one another to allow the installation of the unit in a corner, and have extra tappings in the middle as standard to be used with multiple heat sources, low and high grade heat sources, or varying return temperatures as required for the installation.

A dedicated high-recovery corrugated stainless steel domestic hot water coil is included within all tanks in the MST range, used for the instantaneous heating of potable water. The vessels can additionally include 0, 1, or 2 internal heat exchange coils for use with primary or renewable heat sources. These heating coils are suitable for use with glycol-filled systems such as heat pumps or solar installations.

Almost any heating application can be served by the Adveco MST range, providing an effective heating and hot water solution without the need for additional vessels. Standard vessels are available from 600 to 2000 litres, and bespoke tanks can be designed upon request for applications that require special features.
