Scania Adds Advanced Climate Test Facility to Its Technical Centre in Sweden
SÖDERTÄLJE, Sweden -- November 11, 2013
Scania’s (STO:SCVA)(STO:SCVB) SEK 400 million investment in Europe’s most
advanced climatic wind tunnel for full-size trucks and buses will today be
officially inaugurated by Annie Lööf, Sweden’s Minister for Enterprise, Energy
and Communications, and Scania’s President and CEO, Martin Lundstedt.
With the climatic wind tunnel, located at the research and development centre
in Södertälje, Sweden, Scania can subject test vehicles to the most demanding
weather conditions on home ground, thereby speeding up development and
Scania will now be less dependent on field testing and, using the wind
tunnel’s controlled environment, can shorten lead time from development to
“This unique facility will help us improve fuel efficiency and reduce
emissions even further,” says Harald Ludanek, Executive Vice President for
Research and Development. “Because we can reduce the impact of snow, rain and
dirt, drivers will benefit from a better cab environment and enhanced safety.”
Arctic chill to scorching heat
In the facility, temperatures between -35 and +50 degrees Celsius can be
simulated, as well as humidity of between 5 and 95 percent. The air channel
system is equipped with a number of small snow cannons to produce various
types of snow. The snow can be replaced with rain of whatever intensity
desired, and even the drop size can be altered. By adding an ultraviolet (UV)
visible chemical to the rainwater, and subsequently illuminating the test
vehicles with UV light, it is possible to determine exactly where rainwater
and dirt have stuck and how they flow off the vehicle.
The test vehicle is parked on rollers – one for each set of wheels. These
allow technicians to simulate speeds of up to 100 km/h, the optimal pace for
testing trucks and buses.
Among tests that will be carried out are how components withstand heat and
chill, how rainwater flows off vehicles, driver visibility in heavy rain and
snow, windscreen icing, wind noise and how dirt adheres to cab sides, rear
view mirrors and door handles.
“Scania’s trucks and buses are designed to offer the best performance,
regardless of climate,” says Christer Ramdén, Head of Vehicle Performance
Testing. “As we enter new industrial segments and markets, with increasingly
challenging climatic conditions, we need to ensure that our vehicles will
Houses a 13 square metre nozzle
Construction of the 25-metre tall building was started in 2011 and completed
earlier this year, when extensive testing of the complex systems took place.
The sheer size of the building is needed to accommodate trucks and buses and
the huge nozzle, with a surface area of 13 square metres, from which air is
forced past the vehicle and then fed up to a fan on the upper level of the
The climatic wind tunnel offer advantages such as performing tests under
near-Arctic conditions in the middle of summer and, conversely, simulating
scorching heat in winter. Above all, the facility offers opportunities for
reliable repetitive testing. Based on actual road segments in Europe and
elsewhere – which have been carefully documented and recorded – tests in the
climatic wind tunnel can be programmed to precisely simulate these segments.
Versatile tests for better performance
· In heavy rain, tests can be carried out to assess water intrusion in air
intakes and its effects on wiper functions, how the climate system performs
and mist removal.
· In snow, tests can determine snow clogging on front lids, snow intrusion in
air intakes, snow clogging of filters as well as wiper and defroster
· Sunshine can be generated with a radiation intensity of 400–1,100 W/m² on
the front, roof and cab sides. Cloud and tunnel functions can also be
simulated. Tests can thereby show how the climate system copes with heat.
· By adding 0.5% fluorescent chemical to rain water, tests will show
contamination of sides and door handles, windscreen and side window
visibility, and how exterior driving mirrors are soiled.
· Aero-acoustic tests can be carried out to measure wind noise, also with a
lateral wind flow.

Photos from today’s inauguration ceremony will be available at the pressroom
from 16.30 CET.
Scania is one of the world’s leading manufacturers of trucks and buses for
heavy transport applications, and of industrial and marine engines.
Service-related products account for a growing proportion of the company’s
operations, assuring Scania customers of cost-effective transport solutions
and maximum uptime Scania also offers financial services. Employing some
