Insulated hydraulic coupling SHE-OC up to 40 kW 1'' EPP 402040

Hydraulic decoupler – independence of heating circuits and boiler protection

The SHE-OC hydraulic decoupler is a key element in medium and large-power heating installations, especially where there are several heating circuits (e.g., underfloor heating, radiator heating, DHW) or more than one boiler. Its task is to separate the boiler circuit from the heating circuit, ensuring their independent operation and eliminating interference with pump operation. This solution avoids the need for complicated flow balancing and protects the boiler from low-temperature corrosion by maintaining the appropriate return water temperature.

The insulated version with EPP forms and thick-walled black steel powder-coated in antique gold minimizes heat loss and provides an aesthetic appearance. The decoupler design has been enriched with a sludge trap, drain valve and automatic air vent, making maintenance easier and ensuring long-term trouble-free operation. Additionally, the presence of a capillary pocket allows for easy installation of a temperature sensor.

Construction and functionality for professionals

The SHE-OC decoupler is characterized by a solid construction – a vertical tank with conical bottoms facilitating venting and sludge removal. It is equipped with four PN16 connection ports (depending on size), an upper ⅜’’ socket port with an automatic air vent and a lower ½’’ port with a drain valve. Inside there is a sludge trap and a measuring tube for a possible sensor installation. EPP insulation provides high thermal insulation efficiency (0.025W/mK). This makes the decoupler ideal for use in demanding central heating installations.

Key features:

• Power up to 40 kW (at dT=15K) – performance adapted to the needs of medium and large installations.
• Connections DN25, internal thread 1” – standard size facilitating integration with existing systems.
• Sludge trap, drain valve, automatic air vent – elements facilitating servicing and maintenance of the installation.
• EPP insulation – minimizing heat loss and high energy efficiency.
• Compatibility with connection manifolds and pump groups – possibility of expanding the installation without having to replace the decoupler.
• Durable construction made of thick-walled steel powder coated - guarantee of long-term operation even in difficult conditions.

Application and benefits for the end user

The SHE-OC hydraulic decoupler is an investment in the comfort and safety of your heating system. It ensures optimal operation of the installation, regardless of the heat demand in individual circuits. This allows you to enjoy a stable temperature in every room and save energy. Additionally, the sludge removal function protects against damage to the pump and other installation components, and protection against low-temperature corrosion extends the life of the boiler. Installing the decoupler allows for smooth operation of the entire system without interference caused by different loads on individual heating circuits.
