Shunt unit with a compact design for heating
Shuntopac® 20-40 Komp is a shunt unit with a compact design for radiator, ventilation and floor heating systems where pumps with a union connection have been selected.
Shuntopac® 20-40 Komp is available as standard with connection dimensions from DN 20 up to and including DN 40. The shunt unit can be equipped with several components of any make and a number of different coupling alternatives.
TTM Shuntopac® 20-40 Komp comes with a fire and corrosion-proof casing made of polyester-covered aluminium sheet with mineral insulation.
The brackets for hanging enables different installation positions. TTM Flexfit connection bends for increased flexibility during installation are available as an option, see page 6.
The pipe mixing loop consists of fully welded pressure vessel pipes SS-EN 10216-2 and DIN 2391. The design of the pipe system creates a barrier against unwanted heat transfer due to double circulation, at specified installation positions.
TTM Shuntopac® 20-40 Komp has a EC Declaration of Conformity according to the Machinery Directive 2006/42/EC. “Partially completed machine.”
The shunt unit is environmentally assessed.

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.
