Fabricated solutions for apartments

Compact solution for zone control of small circuits, enables setting of max. flow and prevents radiator and control valves from too high differential pressure. Flexible solution for easy installation thanks to prefabricated unit prepared for energy meter.

Key features

7 in 1 concept reduces costs

Installing one unit with 7 functions reduces investment costs and installation time.

Highly reliable

Pressure tested pre-assembled unit reduces the risk of leakage.

Saves energy and money

Balanced and pressure independent circuits protects systems against over flows and too high energy consumption.

Zone control

Time controlled circuits can save up to 20% energy.

Noise protection

Differential pressure control protects radiator and control valves from too high differential pressure.

Technical description

Application:

Heating and cooling systems.

Functions:

Pre-setting (max. flow)
Differential pressure control
Control
Measuring (ΔH, T, q)
Shut-off
Strainer
Prepared for energy meter

Dimensions:

DN 20

Pressure class:

PN 10

Differential pressure (ΔH):

Max. differential pressure (ΔH_max):
400 kPa = 4 bar
Min. differential pressure (ΔH_min):
DN 20 LF: 19 kPa = 0,19 bar
DN 20 NF: 27 kPa = 0,27 bar
(Valid for the most demanding settings. Other settings will require a lower ΔH. Check with graphs under "Sizing".)

ΔH_max = The maximum allowed pressure drop over the circuit, to fulfill all stated performances.

ΔH_min = The minimum needed pressure drop over the circuit, for proper differential pressure control.

Setting range:

Indication of recommended setting range. For more detailed information see "Sizing".
DN 20 LF: ΔpL 10 kPa, 60-300 l/h
DN 20 NF: ΔpL 10 kPa, 160-840 l/h
(LF = Low flow, NF = Normal flow)
