2. Specification
2.1 Use
Dehumidifiers, which function according to the adsorption principle, are deployed for drying functions
in process engineering, air-conditioning technology, and air-dehumidification in production and
storage spaces, inside which products and installations require particularly low humidity. Drying Unit
U-5003 with integrated humidity control has been specifically designed for being deployed in drying
storage cabinets and drying rooms, in which a particularly low residual moisture content is of specific
importance.
2.2 Operating conditions
In general, dehumidifiers made by Totech are designed for initial conditions of 20-40°C at 0-60%RH.
The process air decreasing relative humidity and/or the regeneration air increasing relative humidity
will adversely affect dehumidification performance.
✓Ensure to exclusively operate the dehumidifier in ambient temperatures (control-side) ranging
between -20°C and +40°C!
✓The process air intake temperature may not exceed a maximum of +60°C; the regeneration
air intake temperature may not drop below the minimum of -15°C!
✓Ensure the intake air does not contain any free water (water drops)!
✓Ensure dehumidifiers are not mounted in and/or exposed to the intake of liquids (e.g. filled
tanks or sumps, flooded areas etc.).
✓Any operation in and/or with potentially explosive ambience is not permissible.
✓In case contaminated air is used for pressure admission, ensure to consider respective
adverse effects on the adsorbent!
2.3 Function
The device has been equipped with a custom-programmable logic module, mounted in the cabinet.
The respective module serves to control the device's humidity, temperature, and functions monitoring.
It provides an external display, indicating several reports such as malfunction, alarms, actual and
pre-set values. Individual data can be retrieved by pressing the control panel's pushbuttons, whereas
fault reports are given highest priority.
In order to ensure ideal dehumidification, the zeolite-filled drying unit requires adequate regeneration.
Therefore the device has a dynamic regeneration cycle. This means when the set point cannot be
reached within a preset time, the dry-unit will start a regeneration cycle automatically. The minimum
time between 2 regeneration cycles is 3 hours to protect the desiccant material inside. Each individual
regeneration cycle will take about 30 minutes. During regeneration processes, active dehumidification
is not feasible.
In order to facilitate the cabinet's tempering an additional circulating air-heater - depending on
respective design models - can be installed.
The air temperature can be controlled by means of the logic module, integrated with the drying unit.
The function is operated via the central text display. The cabinet heater will be deactivated during the
regeneration process and in case of sensor failure.
An alternative option is using an additional heater functioning as a stand-alone unit.
The regeneration process of the dry unit generates heat, which causes a short-term increase in
temperature inside the cabinet. The net increase is dependent on many factors, and a net increase of
5°C is not uncommon.

7. Calibration
Totech recommends annual calibration inspection or the system's calibration by sensor replacement,
respectively. For the drying unit's calibration, we recommend the following two options:
1. Replacing the sensor by a factory-calibrated sensor. After detaching the screw-fastened
retaining ring, the plug-in sensor can simply be unplugged. The replacement sensor is
mounted in reverse order. Since all settings have been stored in the sensor, its replacement
will serve to calibrate the dehumidifier overall measuring. Additional measurement equipment
or software is not required.
2. Define deviations by means of a calibrated reference dew point meter (minimum accuracy
±0.2%RH or higher), and calibrate the sensor via the software's calibration function. This
proceeding requires data connection to PC and software (for detailed instructions, please refer
to the Software Manual of the manufacturer).
8. Maintenance
Ensure to generally disconnect the dehumidifier from the electrical power supply before opening or
disassembling the device.
Ensure all motors - in particular ventilators - are at standstill before reaching inside the device!
In case the dehumidifier was in operation, please allow a cooling time of at least 30 minutes before
disassembling the device!
General maintenance; Dehumidifier U-5000 has been designed for maintenance-free long-term
operation. A maintenance schedule does thus not exist.
