SPERRE RACK COOLER
Solving seawater cooling
”
We have improved the proven technology.
By combining the benefits from box- and platecoolers we have developed the new standard
for seawater cooling, Sperre Rack Cooler.
We have improved the proven technology
BOX COOLER
Constant and efficient cooling
Energy saving solution
Saves space in engine room
Standarizes steel-structure
Maintenance friendliness
PHE
SPERRE RACK
COOLER
Constant and efficient cooling
Predictable – No downtime
Forced sea water flow ensures predictable cooling
Self cleaning sea water filter
Cooling capacity independent of ship service speed
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 solution
Fuel savings - Emission reductions
Frequency operated sea water pump save fuel
Reduced energy consumption on the seawater-pumps
due to low pressure drop
Rack cooler have no marine growth due to
CuNi 90/10 and antifouling paint
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
MARK REEVES, COO AT MAC OFFSHORE
Save space in the engine room
Integrated – Space saving
Other
Integrated in the ships steel structure
- normally between frames in double-bottom
Sperre Rack Cooler
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-structure
Flexible – Module based cooling system
Sperre Rack Cooler – Standard
model
Different type of engines and equipment
- Same steel-drawings
Scalable
Sperre Rack Cooler – Extended
model
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
Maintenance friendliness
Easy access for inspection and maintenance - No special qualification
requirements
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 while the ship is in
operation
