A vessel with class wool insulation all around makes up the unit. Inside the vessel is a copper helical coil that is fixed. At the centre of the coil is a fixed motorised agitator. A controller is also provided for the vessel, along with an electric heater. Cold water is pumped through the chute while the heater warms the water in the jacket. Heat transfer coefficient at different agitator speeds can be calculated by measuring the temperatures of the water that is circulated and the water inside the vessel.
