Climatic chambers coupled with rolling road dynamometers are manufactured by ACS in partnership with companies that are leaders in the technology of chassis dynamo meters. This kind of climatic chambers allows testing of the efficiency of the engine compartment under climatic stress during typical cycles of a vehicle’s working life according to international automotive standards. If an appropriate gas collection and analysis system is installed, the equipment can be used to perform emission tests according to standardized worldwide guidelines.

Dry air is blown into the chamber for the engine combustion. An air pressure regulation system provides the pressure balance of the exhaust gas in order to ensure the correct working of the engine. A wind simulation system following international standards for emission tests can be installed by ACS. Also, a Sun Simulation system can be installed should combined tests have to be performed.
