Hydrualic switch DN 25 – horizontal

The horizontal hydraulic separator with insulation is installed upstream of the heating circuit manifold on the generator side. It hydraulically separates the primary from the secondary circuit and thus makes it possible to create different volume flows on the consumer/generator side. This enables the pumps to operate independently of each other in the optimum efficiency range. As a result the temperature control of the consumer circuits is relieved because of less strong fluctuating pressures in both chambers of the manifold.
