Hydraulic decoupler – the key to a stable heating installation

The BLH 801 hydraulic decoupler is an indispensable element in modern heating systems, ensuring optimal operating conditions for the heat source and the heating installation. The device serves to separate the hydraulic circuits, which translates into smooth operation, increased pump life and effective venting and dirt separation. This is particularly important in installations with multiple heat consumers or powered by heat pumps and condensing gas boilers.

Thanks to its design, the BLH 801 decoupler allows for automatic balancing of flows between the pumping circuits of the heat source and the heating installation. This eliminates the problem of mutual influence of pumps and ensures stable system operation even with fluctuating heat demand. Additionally, the drain valve allows for easy removal of sediment and contaminants, which translates into a longer lifespan of the entire installation.

Comfort and functionality in one device

The BLH 801 model is factory-equipped with a number of amenities that facilitate installation and operation. EPP insulation minimizes heat loss, and the two-part design allows for easy mounting of a temperature sensor. The automatic air vent with a bottom valve and the KFE drain valve are elements guaranteeing trouble-free operation of the device. Two built-in thermometers allow for constant monitoring of the temperature in the circuit.

• Circuit separation: Ensures independent operation of the heat source and the heating installation.
• Hydraulic balancing: Automatically adjusts flows, eliminating problems with underheated rooms.
• Pump protection: Reduces the load on circulating pumps, extending their lifespan.
• Venting and separation: Facilitates the removal of air and contaminants from the installation.
• High quality workmanship: Steel body with galvanized coating guarantees durability and corrosion resistance.
• Complete equipment: Insulation, automatic air vent, drain valve and thermometers as standard – ready for installation!

The BLH 801 hydraulic decoupler is intended for use in heating installations with a maximum operating temperature of 90°C and a maximum pressure of 6 bar. Connections with dimensions of G1” and G1/2” ensure compatibility with most heating systems available on the market. The device is an ideal solution for both professional installers and end-users looking for a reliable and effective solution to optimize the operation of the heating system.
