Ultra Light and Compact HVAC
UniqUe compact HVac to coVer from a to c segment
Best in Class in Size and Weight
Added Value:
• contributes to co2 reduction › requirement of light and compact for achievement of regulation
• standardized modular design › common parts across car segments › compact HVac enable larger cabin space and flexible instrument panel design › shortens development lead time
• global footprint › HVac module can be produced close to the customers
Specification:
eliminates the turbulence zone and creates an even air velocity profile for low air noise and high air flow volume
film type mode and air mixing flap for compact HVac module
new housing material - glass bubbles in polypropylene for weight reduction
