A HVAC system is offering ABB a
double advantage by controlling the
air quality in its Vuosaari factory in
Finland that produces Azipod, a
podded, electrically driven marine
propulsion unit, while simultaneously
being used for the functional testing
of its products.

BACnet-enabled ABB low voltage
AC drives within the HVAC system
are providing the functionality to
achieve this dual application. Thirty
standard drives for HVAC control
the pumps and fans. As well as
monitoring heating and air
conditioning throughout the site, the
building automation system
monitors the flow and temperature
of air used by air-cooled Azipod
propulsion units undergoing testing.

The BACnet system is divided into
three sub-networks: one for the
office block with five air handling
units; one for the factory unit with
three air handling units; and one air
handling unit dedicated to supplying
cooling air for the product testing.
