Seawater cooling


Seawater cooling is a sustainable cooling technique.

The seawater is, for example, used to cool ventilation systems, where the seawater's natural low temperatures cool the water in the buildings' secondary system, which helps to save on energy consumption.

Seawater cooling is also widely used in processes / productions together with internal central cooling systems.- Cooling of internal cooling circuits.

From October/November until April/May in Denmark, the seawater temperature is relatively low and can therefore be used to cool down.

The seawater exchangers, which are a large part of the system, must of course be maintained, as mussels, grass, sand and other good things from sea gets stuck in the heat exchanger and then the performance drops.

A CIP agreement - read more here (ongoing maintenance) can extend the life of the exchanger.

Below you can see an exchanger where the channels are clogged with mussels, shells etc.

Here the exchanger had to be disassembled and thoroughly cleaned. The plates have been at service center for complete refurbishment.


Filter solutions

There are many different filter solutions. You can find some of them below
The Alfa Laval filter (ALF) consists of a series of automatic self-cleaning filters that are mainly used to protect heat exchangers from clogging and soiling. The filter is used in various industries, where cooling systems use, for example, seawater as cooling water.
Filters from Dango & Dienenthal GmbH are also represented here and are also used in industries where seawater can create challenges with clogged exchangers.
