Hydraulic Separator SNT25 on the plate

• What distinguishes it:

It is a product ready for installation with the connection accessories for the circulation pump already arranged. This greatly helps to plan the installation work in the boiler room.

• What is a hydraulic separator used for:

In mixed central heating systems (i.e., those with both radiators and underfloor heating), couplings are used to allow separate circulation for the underfloor heating and radiator systems. This helps to balance the pressure and temperature in both systems, without causing flow imbalances that can occur when separate pumps are used for each system. The hydraulic coupling balances the flow rates throughout the building, and without it, the circulation pump in the boiler would not be able to meet the heating requirements, leading to insufficient heating in certain rooms or parts of the system.

A hydraulic coupling is not a heat exchanger because it does not completely separate the circuits but allows the fluids to mix. However, this can be an advantage in many cases because the temperature is also balanced in the coupling, protecting heating devices such as gas boilers or pellet boilers from "cold return," which occurs when the water returns to the system overly cooled. This phenomenon can significantly shorten the life of heating equipment in poorly designed systems.

If the hydraulic coupling on the plate is unsuitable due to a lack of space in the boiler room, you can also check our couplings that can be purchased separately.
