Hydraulic separator (definition)

Hydraulic separator (hydraulic arrow) — is a device used in heating and hot water supply systems to ensure efficient operation and separation of different circuits or systems with different parameters. Its main function is to equalize pressure and prevent mixing of flows between the primary and secondary circuits of the system.

Hydraulic separator: main characteristics

1. Structure:
   • Frame: The main part of the device, containing several inputs and outputs for connecting various circuits.
   • Internal elements: Includes partitions or structures that provide separation and direction of fluid flow.
2. Function:
   • Separation of contours: Separates circuits with different temperature or pressure conditions, preventing flow mixing and ensuring optimal operation of each circuit.
   • Pressure equalization: Helps maintain stable pressure in systems, compensating for pressure drops and preventing water hammer.
3. Advantages:
   • Improving efficiency: Provides a more uniform distribution of heat and water throughout heating and hot water supply systems.
   • Noise reduction: Reduces noise caused by hydraulic shock and uneven flow distribution.
   • Simplifying adjustments: Facilitates the setup and control of the various circuits of the system, allowing their operation to be easily adjusted independently of each other.
4. Installation:
   • Accommodation: It is usually installed in the central part of the heating system, where it can separate the primary circuit from the secondary or several secondary circuits.
   • Integration: Connects to the system piping in such a way as to divide and balance the water flows between different sections of the system.
5. Application:
   • Heating systems: Used in multi-circuit heating systems to separate the primary circuit (for example, from a boiler) and secondary circuits (for example, radiators, heated floors).
   • Hot water supply: Used to control flows and pressures in hot water supply systems, especially in systems with multiple water intake points.

Example of use:

In a heating system with multiple circuits, such as radiators and underfloor heating, a hydraulic separator ensures that each circuit operates independently at optimum parameters, preventing pressure drops and ensuring stable and efficient heat distribution.
