ACM = Air Classification Module.

Reduce intake of undesired levels of unhealthy and unpleasant gases to an absolute minimum in a car.

ACM is equipped with 2 Sensing Elements, for detection of:

NOx CO and so called VOC’s Volatile

Organic Components associated with unpleasant manures such as compost, asphalt.

Air taken in is classified on quality by the ACM. Classification data is provided to the ECC electronics of the car. The ECC controls the recirculation valve based on user settings, ACM data.

TIH ACM Line OverviewConcept MWE Concept discussion

Frame-Welded steel

- supports dial table, desktop, mounting plate for units at outer ring

Desktop- wood

- Sustainable steel top layer (ESD)

Suction hood- Doors from all sides

Trays-Output: Membrane assy

Monitor- Displays equipment

status

-Lifted, rotated

Box-Input: Housings (bulk)

Control box-Can be reached

from the right

19” rack- Drawer with keyboard

- Controls

Control Buttons-Hardware

-Including Emergency stop, Abort, Ackn., …

Reserved space- Pneumatics ( reducing valves, tubes, …)

- Electrics (cables, …)

Light curtain-Safety; used for start

4 Pressure test & Bad Unload

3 US Cut & Seal Nest with Housing

TIH ACM Line OverviewNew Interface Layout MWE

Split level inner and outer ring for Laser Weld Equipment:- Simple frame

- Dial table is mounted ON frame

- More rigid outer ring

- Contacting at lower side more easily

- More space for side equipments (pneumatics, valves, …)

-

Wooden desktop for operator

Aluminum mounting plate at frame for units
