TTM Shuntopac® 125-200 V

Shunt unit for heat

TTM Shuntopac® 125-200 V is a shunt unit for district heating systems and conventional radiator, ventilation and floor heating systems. The shunt unit is available as standard with connection dimensions from DN 125 up to DN 200. It can be equipped with several components of any make and a variety of connection options.

TTM Shuntopac® 125-200 V is supplied with fire and corrosion resistant aluzinc sheet metal cover and mineral wool insulation. The shunt unit has a stand with four legs and foot plates for floor set-up and attachment.

The standard version pipe package consists of fully-welded pressure vessel pipe SS-EN 10216-2. The pipe package can be delivered in other qualities or with other surface treatment on request. The design of the tube bundle, in the specified mounting positions, provides a barrier against unwanted heat transfer due to double circulation.

TTM Shuntopac® 125-200 V is CE-marked in accordance with the manufacturer’s declaration 2B according to the Machinery Directive.

The shunt unit is environmentally approved.

C – A Available pressure difference on primary side.

H – B Pressure rise over the control valve.

Secondary side

D – E Measuring of the pressure difference over the adjusting valve on the secondary side.
Secondary flow can be determined with the help of data for the adjusting valve.

F – D Pressure drop in connected object on secondary side.

G – F Pressure set over the ciculation pump.
