The Lotus joint can also be called a mixed jug. 
In the heating of water system, due to the existence of hydraulic coupling between the circuits, when the flow of a branch or user changes, the rest of the branch or the user's flow and boiler flow will be affected.
Thus the hydraulic balance of each loop loop is breached. The device is called the Lotus root tank by creating an area where the pressure loss is close to zero, allowing the pump to achieve its own circulation, non-interference, heat-free transfer device, and decoupling treatment.

Product Features

In the modern heating system, the hydraulic voltage divider mode of one/two times system realizes a variety of heating methods, and converts the large circulation into a number of small circulatory systems with low energy consumption, and realizes the energy saving standard.
The coupled tank hydraulic divider is composed of the following functional elements:
1. Hydraulic division pressure: so that each branch of the waterway relatively independent operation.
2. Sewage: separation and precipitation system impurities, and then through the sewage valve to eliminate.
3. automatic exhaust: Through the automatic exhaust valve automatically eliminate the presence of air in the system.
