The Hydronic Balancing Training Unit, "THBT", has been designed to study the amount of water that guarantees enough provision of hot water to all the radiators in a system. The hydronic balancing is performed with lockshield valves, which block the circulation of a fluid in one direction and allow it to circulate in the opposite direction.
The unit has several heating circuits that consist of radiators, balancing valves, differential pressure overflow valve, automatic air vents and a circulating pump. The circuits are made with commercial components and each circuit can be shut off individually. When the circuit is filled, it is independent of the water mains or feed flow and return flow pipe connections, although it can also be used together with a heating circuit.
Each radiator has a thermostatic valve, a bleed valve and an adjustable lockshield valve.
