LOUVRES
allowed to take up in the wind turbine
doors.”
Engineers from both Renson and EWT
put their heads together to find the perfect
louvres of this application. “As part of this,
Renson showed the necessary flexibility to
develop louvres that met our specific
(burglar resistance) requirements. Our
partnership with Renson could not have
gone better, and after validation in our test
turbines using CFD analyses, we gave them
the green light to install the louvres at our
Westeinde wind farm in Anna Paulowna,”
Danny concludes.
Hans Bannink (Renson): “The ventilation
louvres in question were fitted with an
additional removable frame with a dust
filter and special mountings for easy
installation in the doors of the wind
turbines. The main reason for these filters
was to protect the advanced equipment
inside the turbine against unwelcome
visitors and outside influences such as
torrential rain or storms. The fact that they
are easy to replace helps limit the pressure
drop. Eventually, two types of louvres were
developed to maximise the flow of fresh
outside air for each door in order to
provide the necessary cooling.”
Danny: “These ventilation louvres offer us
extra flexibility in hotter areas, as well as the
option to install an internal transformer. This
has enabled us to expand our product
portfolio in response to demand from the
market and specific environmental
requirements. The straightforward
installation process also gives us the
flexibility to add the louvres at the last
minute,” Danny Ferket concludes.
