The functional principle
An air stream that is temperature conditioned and/or air conditioned precisely to the entered set values continuously flows through the test space and ensures an optimum spatial distribution of air and temperature with best constancies in terms of temperature and humidity.
Generously dimensioned axial fans with an external drive motor draw the air out of the test chambers. This circulating air then flows through a fin-type heat exchanger in which it is cooled if required. An electrical heater installed behind the heat exchanger
heats the circulating air. The stream of air then passes over a water bath; integrated heating elements ensure quick and precise heating of the water.
The humidity of the test space air is measured psychrometrically. Depending on the climate the humidity sensor thermometer is wetted automatically and cleaned in the process. This considerably increases the service life.
