Cooling Systems
The Cooling Systems business unit offers equipment
and services intended to cool water through
contact with air and to condense steam resulting
from the production processes of power stations
and heavy industry most notably chemicals,
petrochemicals, iron and steel, paper making, and
sugar refining.
or ‘wet-dry’ or ‘humid-dry’ system. Dry cooling systems
(air cooled condensers or indirect systems) allow the
cooling of the steam in closed circuits, without water
consumption and without release of plume. They are
therefore the solution to cooling problems in areas
where water is scarce, for example in parts of
continental China, South Africa or the Middle East.
Products and services
Hamon delivers technical solutions adapted to the
needs and requirements of its customers: electric
power plants, engineering companies of international
renown and industries.
The evaporative cooling systems are differentiated by
their method of air flow generation: natural draft in the
case of a chimney or induced draft when fans are used
and whether they include or not a system reducing or
eliminating the visibility of the plume: so-called ‘hybrid’
Contribution to our society
For users which are producers of electricity, the social
contribution of the cooling systems is to facilitate the
production of more electricity for a given consumption
of primary energy. If the cooling water from the cooling
system is two degrees Celsius colder, the output of a
steam turbine increases by approximately 0,6%, which
corresponds to an increase of more than one percent
in the electricity output. For a same production of
electricity, it allows to consume less primary energy
(coal, gas, etc.) and therefore to release less CO 2
into
the atmosphere.
