TTM Shuntopac® 20-50 V

Shunt unit for conventional radiator, ventilation
and in floor heating systems

Shuntopac® 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® 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 loops 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.

TTM Shuntopac® 20-50 V is CE marked in accordance with manufacturer’s declaration 2B according to the Machinery Directive.

The shunt unit is environmentally assessed.

Applications:

  • Radiator systems
  • Underfloor heating

TTM Shuntopac ® 20-50 V differential pressure measurement

All outside valves on the TTM Shuntopac® 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.

E – B Pressure drop over the control valve.
