The main function of WL 312.11 is to provide a cold water circuit for experiments with WL 312 and WL 315C. The supply of cold water enables meaningful operation at high ambient and water temperatures.
The supply unit is equipped with a closed cooling unit including refrigerant circuit, a water tank and a pump for the cold water circuit as well as a switch cabinet with displays and controls.
The supply unit cools the water in the water tank. A pump transports the cooled water from the water tank through hoses to the WL 312 or WL 315C trainer (feed). From the WL 312 or WL 315C trainer, the water flows back into the water tank of the supply unit (return) via pipes.
The flow rate in the cold water circuit is adjusted by means of valves.
The temperatures of the water in the flow pipe and in the return pipe are displayed. The flow rate is displayed by means of a rotameter.
