Scania adds advanced climate test facility to its Technical Centre in Sweden

Scania’s 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 improving
performance.

Scania will now be less dependent on field testing and, using the wind tunnel’s
controlled environment, can shorten lead time from development to product
launch.

“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
perform faultlessly.”

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 facility.

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 functions.

  · 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.

ceremony will be available at the pressroom from 16.30 CET.
