Autonomous cooling units are necessary when using butt welding machines, because the machines that produce today and produced before, have an open cooling circuit, the machine has fittings "inlet" for coolant supply and "outlet" for draining coolant.
This design involves the use of running water. The cooling unit allows you to close the cooling circuit. The closed-circuit requires a small amount of coolant, which allows the use in the cooling circuit of distilled water or antifreeze at low temperatures.
The scheme of the cooling circuit BAO is made in such a way that reducing the water pressure at the outlet will not lead to an overload of the pump motor. The taps required for the proper cooling of the machine are installed directly above the drain hole of the storage tank.
BAO is easy to operate and simply connects to the cooling circuit of any machine.
