TTM Shuntopac® U 20-50 V

Shunt unit for heat

TTM Shuntopac® U 20-50 V is a shunt unit for conventional radiator, ventilation and in floor heating systems and is available as standard with connection dimensions from DN 20 to DN 50. The shunt unit can be equipped with several components of any make and a number of different coupling alternatives.

TTM Shuntopac® U 20-50 V comes with a fire and corrosion-proof casing made of polyester-covered aluminium sheet with mineral insulation.

The hanging brackets consists of yellow chromated flat bars.

As standard, the pipe mixing loop consists of fully welded pressure vessel pipes SS-EN 10216-2 and DIN 2391. Pipe mixing loop in other qualities or with other surface treatments can be delivered to order. The design of the pipe mixing loop works as a barrier against undesired heat transmission due to double circulation.

EC Declaration of Conformity according to the Machinery Directive 2006/42/EC. “Partially completed machine.”

The shunt unit is environmentally assessed.

Equipment

TTM Shuntopac® U 20-50 V differential pressure measurement

All outside valves on the TTM Shuntopac® U 20-50 V are provided with test sockets, allowing complete differential pressure measurement.

B – A Measuring of the pressure difference over the adjusting valve on the primary side. Primary flow can be determined with the help of data for the adjusting valve.

C – A Available pressure difference on primary side.

G – H Pressure rise over the circulation pump.

H – D Pressure drop in connected object on 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 – B Pressure drop over the control valve.
