1. SPERRE RACK COOLER Solving seawater cooling

2. ” We have improved the proven technology. By combining the benefits from box- and plate- coolers we have developed the new standard for seawater cooling, Sperre Rack Cooler.

3. We have improved the proven technology BOX COOLER PHE SPERRE RACK COOLER Constant and efficient cooling Energy saving solution Standarizes steel-structure Maintenance friendliness Saves space in engine room

4. Constant and efficient cooling Predictable – No downtime Cooling capacity independent of ship service speed Self cleaning sea water filter Forced sea water flow ensures predictable cooling Heat transfer (K-value) 3 times as high as box coolers

5. ” After a year in operation, we have not experienced any problems and we have not had to open the cooler even once. We are installing Rack in our upcoming new buildings NARVE RØSOK, TECHNICAL MANAGER AT ROSTEIN

6. Energy saving solution Fuel savings - Emission reductions Rack cooler have no marine growth due to CuNi 90/10 and antifouling paint Frequency operated sea water pump save fuel Reduced energy consumption on the seawater-pumps due to low pressure drop Chilled water element reduces running time at the chilled-water compressors Heat recovery element makes it possible to use the surplus heat ​

7. ” To invest in Rack coolers was for us a no-brainer; the combination of space-savings, ease of maintanance and the competitive price MARK REEVES, COO AT MAC OFFSHORE

8. Other Save space in the engine room Integrated – Space saving Integrated in the ships steel structure - normally between frames in double-bottom Reduced piping arrangement - all piping are situated below deck Makes space available for service and gangways Sperre Rack Cooler

9. ” In addition to getting most of the seawater out of the engine room, Rack is very space-saving. It has been a win-win situation to invest in Rack seawater coolers BJØRN HOFSETH, SITE MANAGER AT REMØY MANAGEMENT

10. Standarized steel-structure Flexible – Module based cooling system Sperre Rack Cooler – Standard model Sperre Rack Cooler – Extended model Different type of engines and equipment - Same steel-drawings ScalableLess piping and infrastructure

11. ” The main advantage with Rack is that the system is designed to be integrated in the ships steel structure. Totally this is a system that we have great belief in! TROND HAUGE, TECHNICAL MANAGER AT ISLAND OFFSHORE

12. Easy access for inspection and maintenance - No special qualification requirements Maintenance friendliness No need for dry-docking Few service gaskets – low life cycle costTubes in CuNi90/10 prevents marine growth100% insulated from the hull-structure - No galvanic corrosionAntifouling paint

13. ” There is a great advantage to be able to handle maintenance without having to go in dock. All cleaning can be done at sea while the ship is in operation LARS CHRISTIAN LARSEN, NEWBUILDING MANAGER AT DOF
