SPERRE RACK COOLERSolving seawater cooling

”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.

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

Constant and efficient coolingPredictable – 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

”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

Energy saving solutionFuel 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

”To invest in Rack coolers was for us a no-brainer; the combination of space-savings, ease of maintanance and the competitive price

Save space in the engine roomIntegrated – 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

”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

Standarized steel-structureFlexible – Module based cooling system

Sperre Rack Cooler – Standard model

Sperre Rack Cooler – Extended model

Different type of engines and equipment - Same steel-drawings

Scalable

Less piping and infrastructure

”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

Easy access for inspection and maintenance - No special qualification requirements

Maintenance friendliness

No need for dry-docking

Few service gaskets – low life cycle cost

Tubes in CuNi90/10 prevents marine growth

100% insulated from the hull-structure - No galvanic corrosion

Antifouling paint

”There is a great advantage to be able to handle maintenance without having to go in dock. All cleaning can be done at sea
