Premounted Midi Shunt
Application
Midi Shunt 088U0851
- with one circuit
The Danfoss Midi shunts are used for control of flow
and supply temperature in hydronic floor heating
systems. The compact, midi shunt comes premounted for 1-circuit ready to mount on the wall
and fittings for pipe connection (20 × 2 mm).
The shunts self-acting proportional thermostatic
control valve is used to control the supply
temperature.
The thermostatic sensor ensures that the desired
supply temperature to the underfloor heating
system always remains constant.
Other components in the Danfoss Midi shunt:
• Built-in check valve ensures correct flow direction.
• An air-vent on top and a thermometer for trouble
shooting and service.
• RA-N valve with pre-setting to ensure the optimal hydronic balance in the system.
• UPM3 Auto pump ensures that the energy consumption for the system is kept at a minimum.
• Danfoss Icon™ Dial 230V thermostat for accurate
room control.
Features:
• Compact design — fits in even the smallest places.
• Pre-mounted — minimal risk of installation faults.
• Easy ordering — only one number necessary.
• Short installation time.
• Grundfos UPM3 Auto pump ensures the lowest
possible operating costs.
Should water treatment be used it is essential that
dosing instructions of the manufacturer are strictly
observed. It is recommended that formulations
containing mineral oil are avoided.
