Heater Heater cores cores position position To be sure that no condensation projection from evaporator thecore heater core Proximity between electric or electronic components andon heater hot zones should be avoided create particular odor . No contact between passenger foot and heater core. No condensation projection from evaporator to the heater to prevent particular odor . The better implantation isThe described on the following sketch best position is described on the following sketch (esp. to avoid degazing problem). (to avoid degazing problem).

Heat exchange architecture is optimised thanks to flat tube patented design This technology, as plate fins evaporator technology, eases heater core standardisation ; Branch know how includes a well controlled process able to reach large volumes.
