High-quality, efficient, durable

Heating circuit distributor

The heating circuit manifold plays a crucial role in modern surface heating systems, as it enables efficient and even heat distribution in your building. It ensures precise control and regulation of the individual heating circuits, which increases the comfort and energy efficiency of your heating system. The heating circuit manifold is ideal for underfloor heating, wall heating and other surface heating systems and is used in new buildings as well as renovation projects. It can be used in residential buildings, office buildings and commercial properties.

heizkreisverteiler-automatischer-entluefter

Reliable, Simple, Secure

Automatic vent

The automatic air vents integrated into our heating circuit manifolds remove the air accumulated in the water circuit without requiring manual intervention. This prevents the following negative phenomena that could affect the lifespan and efficiency of the heating system:
• Oxygen-induced corrosion
• Air accumulation in the radiator
• Cavitation in the circulation pump
• Dry running of the pump

Klemmringverschraubung-alex-depot

Robust, connection security, simple

Compression fitting

Compression fittings are essential connecting elements for heating circuit manifolds. They enable the pipes to be installed securely and tightly without the need for welding or soldering. Their ease of use means they offer quick and reliable installation, ensuring stable connections and optimal heat distribution in the heating system.

Stellantrieb-Moehlenhoff

How do you calculate the average temperature difference?

The mean temperature difference of a plate heat exchanger can be calculated by several methods, depending on the type of heat exchanger and the specific conditions. A common method is the Logarithmic Mean Temperature Difference. Here is how you can calculate it:

Formula for the logarithmic mean temperature difference

LMTD = (ΔT1 - ΔT2) / ln(ΔT1 / ΔT2)

variables

  • LMTD: logarithmic mean temperature difference
  • ΔT1: Temperature difference at one end of the heat exchanger
  • ΔT2: Temperature difference at the other end of the heat exchanger

Example

  • Temperature of the hot liquid at the inlet (Th): 150 °C
  • Temperature of the cold liquid at the inlet (Tc): 30 °C
  • Temperature of the hot liquid at the outlet (Th'): 80 °C
  • Temperature of the cold liquid at the outlet (Tc'): 60 °C
1. Calculation of ΔT1 & ΔT2

ΔT1 = Th - Tc = 150 °C - 30 °C = 120 °C

ΔT2 = Th' - Tc' = 80 °C - 60 °C = 20 °C

2. Calculation of the mean temperature difference

LMTD = (120°C - 20°C) / ln(120°C / 20°C)
LMTD ≈ 55.8 °C

How is the heat flow calculated?

Q = U * A * LMTD

  • Q: heat flow (W)
  • U: total heat transfer coefficient (W/m²·K)
  • A: Heat transfer area (m²)
  • LMTD: logarithmic mean temperature difference (K)

or

Q = ṁ * cp * LMTD

  • Q: heat flow (W)
  • ṁ: mass flow rate (kg/s)
  • cp: specific heat capacity (J/kg·K)
  • LMTD: logarithmic mean temperature difference (K)

How should I connect my heat exchanger?

cocurrent and countercurrent principle

The heat energy that can be transferred in a plate heat exchanger is not only determined by the size of the exchange surface and the heat transfer coefficient (k), but is also significantly influenced by the flow directions of the media involved. If both media flow in the plate heat exchanger in the same direction, this is referred to as the cocurrent principle. If they flow in opposite directions, however, this is the countercurrent principle.

The flow direction has a significant influence on the average temperature difference between the media, which in turn determines the efficiency of heat transfer.

Temperature curve with the direct current principle | Temperature curve with the countercurrent principle

Theoretical consideration of the connection options of a plate heat exchanger:

In this example we assume two media with the same heat capacity and the same mass flow.

  • Medium 1: 80 °C
  • Medium 2: 20 °C

With the cocurrent principle, the maximum temperature that can be reached for both media would be 50 °C, which corresponds to the mixing temperature. With the countercurrent principle, however, medium 2 could reach a temperature of up to 80 °C, while medium 1 can be cooled to 20 °C.

This means that the countercurrent principle allows a larger amount of heat to be transferred using the same exchange surface area.

How do I find the right plate heat exchanger for my application?
