Re-engineering the CCU - Climate Control Unit - and HVAC system on Porsche 964 and 993


Recommended Posts

Our latest Youtube video walks through a current R&D project to re-engineer the cabin air circulation and ventilation systems on Porsche 964 and 993 models. This project was a logical progression from an earlier 18-month project to redesign the troublesome Porsche 964 CCU - the dash-mounted control unit - to a fully microprocessor-controlled ECU and deliver a modern solution to a well known problem.

Watch the video below for a sneak peek at the separate project to develop an electric heating system for this 400-volt EV customer. There is some crossover between the two systems (ICE and EV), but the 12v designs are still in the test phase. Due to the controller requirements, the electric heating system will be an addition to our A/C system and not a standalone project.

Best news of the year for the 140k+ 964/993 owners !!
I'm wondering how much weight will be saved on deleting all this heat exchanger/ a/c stuff at the rear !

Better weight distribution anyway !
I think most of us wait for a complete HVAC / a/c / heating / alternator refurbishment/improvement solution to do the job just once.

Keep up the good work !
