Products

Climate Control

• Air conditioning systems and modules (air conditioning loop and modules, including evaporators and heater cores);
• Multi-zone HVAC units for personalized cabin comfort;
• Heating and cooling products (battery thermal management, rear air conditioning, booster);
• A complete range of electric radiators for instant cabin heating;
• Specific air conditioning systems for new drive-trains: storage evaporators that keep AC systems in operation with stop-start systems, and electric air-conditioning systems for hybrid vehicles;
• Air quality products (particle, gas and odor filters, fragrance diffusers, ionizers);
• Derivative products for the aftermarket.

Powertrain Thermal Systems

• Heating and cooling products (radiators, condensers, oil coolers, fan/motor systems, cooling modules);
• UltimateCooling™, which can reduce the number of exchangers needed in the front end, by using a single thermal fluid. This innovative architecture generates fuel savings of up to 9% for vehicles using air-conditioning and also saves space in the front end;
• Air intake cooling modules and charge air coolers (CAC), including the water-cooled CAC which reduces consumption and pollutant emissions through enhanced efficiency in cooling intake air. The traditional frontal air-to-air heat exchanger has been replaced by a new air-to-water heat exchanger. This solution reinforces the trend towards engine downsizing, one of the most promising sources of fuel savings;
• The THEMIS™ system, which improves engine yield with smart temperature control. The major advantages are fuel savings and enhanced cabin comfort;
• The EGR (exhaust gas recirculation) cooler of the EGR system, which takes some of the exhaust gases at the cylinder head outlet and re-injects them into the air intake, reducing nitrogen oxide emissions during combustion and complying with Euro V and VI standards;
• Powerful yet low energy consumption heating systems for electric vehicles (the key technologies developed are heat pumps, heat recovery systems via secondary circuits, and dehumidifying systems).

Compressors

• Compressors for automotive air conditioning systems, including controlled air conditioning compressors, with reduced energy requirements: Vane rotary, fixed-cylinder, variable-cylinder and electric compressors.

Front-End Modules

• A complete range of front-end modules;
• Safe4U™, an active pedestrian detection system using a radar on the upper crosspiece and cameras along the radiator grill. Safe4U™ temporarily separates the upper crosspiece from the front end, allowing it to tip. The system complies with, and even surpasses, current pedestrian protection regulations.
