GEA Heat Exchangers supplies closed-circuit coolers for the Finnish icebreaker Sisu
13. August 2013 In May of 2013, the Estonian ship repair and conversion company SRC Group AS awarded an order to GEA Heat Exchangers for 36 GEA F-tube coolers. The coolers are intended for installation on the Finnish icebreaker Sisu, to profitably transfer the heat emitted by the ship’s generators and propulsion engines.
The order was granted to the company GEA Heat Exchangers OÜ in Estonia. The company GEA Maschinenkühltechnik GmbH will manufacture the coolers in Germany. Delivery is scheduled for October of 2013. The new F-tube coolers will replace old equipment that was originally delivered for the ship in the mid-1970s by GEA Luftkühlergesellschaft Happel GmbH & Co.
GEA F-tube coolers are characterized by great thermal performance in compact space. Their compact structural design is the result of the use of elliptical tubes (“GEA F-tubes”) with cross-sections that facilitate effective flow with low pressure drop. Rectangular fins are slid over these tubes, which are metallically connected to the core tube by dip galvanizing. The slight air-side pressure drop enables low operating costs for the fans.
Sisu belongs to the Finnish icebreaking and ice management company Arctia Shipping Oy’s fleet. It is approx. 100 m long, with a beam of more than 20 m. It and its sister ship Urho are among the largest Finnish icebreakers. With its draft of 8.3 m and its shaft output power of 16.2 MW, it has top speed of 18 knots in open water. During the winter months, the ship is on duty in the Gulf of Finland, between Sweden and Finland in the Bay of Bothnia, and in the northern reaches of this bay.
