Schaeffler temperature control requirements:
For the quality test of the separating clutch, Schaeffler requires a test environment that makes precise simulation of ambient temperatures possible. The challenge is to subject the test specimens to ambient temperatures from -40 °C to +120 °C during endurance tests. To avoid long downtime or waiting periods during stipulated changes in temperature, quick temperature change from +30 °C to -30 °C within 1½ hours is needed. This requires a space saving and compact solution that controls the temperature of air within the hood.
