Traditionally, plate heat exchangers have been employed for decades in the
engine rooms of ships, whether container ships or cruise ships, for the most
varied cooling tasks within the engine room.
SIGMA plate heat exchangers are in use over the seven seas.
Corrosion-proof materials, such as titanium, are employed for the heat exchanger
plates in cases of sea water applications.
Typical tasks for SIGMA plate heat exchanger are:
Central cooling of the main and auxiliary motors
Lubricating oil cooling
Heating of sea water for fresh water generation
Heating of heavy oil or diesel oil
Cooling of engine cooling water
Preparation of circulating water for cylinder and generator cooling
Application example: Shipyard in China
We received an order from a shipyard located in China for the equipping of a
total of 8 ships, distributed over a time period of 3 years. Per ship, 2 central
cooler units SIGMA M229 are employed for the cooling of 550 m³/h fresh
water by means of 620 m³/h sea water, 2 fresh water coolers SIGMA M 66,
1 lubrication oil cooler SIGMA M156 and 1 water cooler SIGMA K 48.
