Gebruder Trox GmbH Heinrich Trox Platz e-mail: [email protected] Product Information Ex Volume Flow Controller TVR-Ex - TES/TEF Use as an fume cupboard controller: In line with this concept, fume cupboards require "constant" control. Operating mode selection is therefore possible by means of external, potential-free circuits (Vmax, Vmin, full shut-off). The pick-off for the monitoring device of the fume cupboards is to be taken from the alarm contacts of the controller. Visualisation (visual- and acoustic alarm) is provided by the explosion proved monitoring that have to be supplied by the laboratory...
