Hydraulic Coupling-Collectors SKE

SKE coupling-collectors are available in standard and Condens (DC) versions. The Condens version is equipped with a patented flow director. The Inox director maintains high efficiency of condensing boilers or heat pumps. The Inox director allows for alternating connection of pump groups with a spacing of 125mm. A version for heating circuits DN32 is also available. The standard version (2D+) offers limited possibilities for connecting pump groups. Universal construction (adaptation kit) enables installation within a 360° range. Connection of two, three, or four (4DC) pump groups is possible. Expansion of SKE 2DC+ for an additional heating circuit (expansion kit, only DN25) is possible. SKE 2DC+ are part of ready-made sets with pump groups – Kompania and Kompania PRO. Products are insulated with EPP molds.

The Low-Loss Header, also known as a Hydraulic Balancer, is designed to separate the boiler’s circulation from the heating system, suitable for medium to high-power systems (25 kW and above, ideal for an average house). It is used in setups with one or more boilers and various heating circuits, such as floor heating, radiators, or hot utility water. The LLH automatically manages flow separation, eliminating the need for manual balancing of pump flows. Its construction includes a desilter and air vent, offering additional benefits of system cleaning and air removal while protecting the boiler from low-temperature corrosion of the return water.

Operational Modes:

1. When the heat requirement equals the boiler’s power, the system operates in balance.
2. If the requirement is less than the boiler’s capacity (e.g., thermostatic valves are closed), some heat returns from the LLH, signaling the boiler to decrease output or switch off.
3. If the requirement exceeds the boiler’s capacity, increased pump suction signals the boiler to produce more heat.

Features of the Low Loss Header SHE 2”:

• Max flow: 7.4 m³/h
• Max power: 156 kW
• Connectors: 4 x 2" male threads
• Nominal pressure: 10 bar
• Max temperature: 110°C
• Capacity: 4 liters (or 1 liter in some configurations)
• Vent and drain valves included

Advantages for investors:

• Up to 30% longer boiler service life through protection from low return water temperatures
• Enhanced operational comfort via system desiltering and aeration
• Up to 30% longer pump service life due to smooth, undisturbed operation
• Faster boiler reactions to changing demands
• Cost savings of up to 50% compared to traditional 3- or 4-way valves

Advantages for installers:

• No need for complex system regulation, thanks to automatic flow management
• Reduced claims caused by air locking or improper operation

Variants Available:

• SHE – LLH: Power range from 40 to 420 kW
• SHE-OC: Insulated with polyprene shell, power from 40 to 156 kW (up to 420 kW can be insulated with ROCKWOOL upon request)

Customer satisfaction benefits from reliable, efficient heating operation with less maintenance and fewer issues.
