U-7100. Operation requirements Totech air dehumidifiers are in general deployed with beginning conditions of 20°C at 60%r.H. With diminishing relative humidity the process air and/or increasing relative humidity of the regeneration air the dehumidifying performance is affected negatively. - Page 6 Construction The air dehumidifier has been equipped completely with Rotor (1), Process-(2)- and Regeneration air- (3)-Ventilator, Drying wheel driven motor (4), Regeneration air -Heater (5), Air filter and electric equipment. Air humidity is adsorbed with the silicagel rotor. Picture 1 Way of operation U-7002/U-7003 During rotation the rotor passes through two sectors (Regeneration (D) and Process (A)).

Regeneration and process air heating The heating of the air will be done by an electric heater. The heater consists of PTC thermistor heating elements that will type of construction adapted their power consumption automatically according to the air flow and inlet temperature. This enables the PTC thermistor, a temperature-dependent semiconductor resistor. -

Sensor exchange Totech recommends to check the calibration once a year or to execute a new calibration of the system by exchanging the sensor. The sensor can be reached easily. By loosening the security ring the plug connection can be separated. - Page 13 Repairs Repairs should only be carried out by Totech service mechanics or relative-skilled personnel. Failures Faults Cause of fault Action Humidity too high Air mixture too low Correction of air mixture Door open Check air filter, exchange if necessary ...
- Page 14 11. Damaging affects on Silicagel Rotors Some of the following materials and compounds are typical of materials which can solve silicagel rotors or influence dehumidification negatively. The sorption rotor should not be moved with air, which is contaminated with these materials or materials resembling them not even in the lowest concentration.
