Jupiter Dynamic S1 manifold with dynamic flow control

The Jupiter Dynamic S1 manifold adjusts the flow rate in the individual heating circuits directly in litres/hour. This means that hydraulic balancing is achieved in one simple operation. The set flow rate is constantly adapted i.e. if the rate becomes too high due to adjacent closing circuits, the Jupiter Dynamic S1 manifold automatically controls the flow to the set value.

 

Traditional underfloor heating manifolds are balanced with all circuits opened. During operation it is likely that not all circuits are open simultaneously. This increases pressure through open circuits which affects output. The Dynamic S1 manifold ensures constant flow through all circuits.

Key features:

Guarantees constant room temperatures

Automatic hydraulic balancing due to integrated flow control inside each thermostatic insert

Flow indicator to check individual circuit operation

Contributes to lower running costs

Time and cost saving commissioning solution

German AISI 304 stainless steel manifold

Function:

A regulating part is set to the calculated control rate by turning the digit cap with the setting key or an 11 mm end wrench. If the flow rate increases at the valve the rising pressure moves the sleeve, thus constantly limiting the flow to the set value. The set flow rate is therefore never exceeded.

If the flow rate drops below the set value a spring presses the sleeve back to its original position.

Sample calculation

Target:

Set value of Jupiter Dynamic S1 manifold flow controller

Given:

Heat flow, heating circuit Q = 1120 W

Temperature spread Δt = 8 K (44/36°C)

 

Solution:

Mass flow m = Q / (c · Δt) = 1120 / (1.163 · 8) = 120 kg/h

Flow regulator setting at manifold: = 12

Q = Heating performance

Δt = System differential temperature

Δp = Differential pressure

Sample:

Q = 1000 W, Δt = 15 K

Setting value: 6 (≈ 60 l/h)

Δp min. 30 - 150 l/h = 17 kPa

Δp min. 150 - 300 l/h = 25 kPa
