What is nice about these evaporators is they give the appearance they are al- most entirely integrated into the body of the vehicle rather than an add-on hang down passengers can hit their heads on. Plus, there are access panels on the units, enabling technicians to easily reach all the fttings and service points on the units as well the blower motors and fans. Cheyne Rauber, GM and sales man- ager for RAC, explains that after live test driving the unit to pinpoint the prob- lem, a four-hole drain pan was sug- gested. Since RAC does all of its met- alwork in-house, Rauber and his team were able to prototype the new bulk- head within a week, and the system wa s i n f u l l p ro d u c t i o n w i t h i n t h re e weeks. Rauber says the best part is that they eliminated the customer problem, while creating a brand new feature on RAC's bulkhead evaporator. Te beneft of the four-hole pan is that no matter the orientation of the vehicle, there is always a positive fow. Tis way, there is never water building up and spilling over the pan, and thus, spilling onto passengers. Additionally, the bulk- head unit has rivnuts mounted on the side of the units, which allows for a wide variety of mounting applications. With this variety, RAC can customize brack- ets and covers to fit any application in the market. Additionally the company has seen success with its new weather pack con- densers, which ofer a weather tight con- nection at all connection points. With the new condensers, the need for ex- posed terminals that can be subject to corrosion, especially in snowy climates, is eliminated. 31 JULY 2014 m ETRO m AGAZINE >
