Drunen, The Netherlands -- Recently, °Celsius delivered a screw heat exchanger to a client in Belgium which cools down more than 2.000 kg Rhenium per hour which is coming out of an incinerator from 850 °C to 150 °C.

The cooling is required because the hot Rhenium can not be handled at the high temperature. Rhenium is a raw material which is added to all kinds of chemical processes in the metal industry in order to add certain improving attributes to the metal to be produced, for instance, durability.

The °Celsius screw heat exchanger consists of a large double-axis screw conveyor with hollow blades, whereby each screw has a diameter of more than 800 mm. The length of each screw is more than 8 meter and both the blades, the screw-axis and the body are cooled by means of cooling water with a temperature of > 20 °C.

Because the production process is in production 24 hours a day/seven days a week/50 weeks per year, production reliability has been an absolute requirement of the client and with the design °Celsius has tried to eliminate all potential risks of failure.

°Celsius is the sister company of the famous company Van Beek Schroeftransport, which has been producing screw conveyors since 1939. Based on its experience of many years °Celsius has established itself in 2002 as an independent and specialist unit for the development and realization of thermal screws.
