The d esiccant wheel and the frame part form the core of the dehumidifier,
whose performance characteristics directly influence the dehumidifier
performance and characteristics:
• Both desiccant rotor and sealing strip are imported material s from USA.
• The desiccant rotor is made by special heat resistance composite
materials, which is corrugated structure containing high performance of
moisture absorption, forms lots of tiny air hole s , has large air contact area,
improving the dehumidification efficiency.
5.4 ZEOLITE
• Reactivation blower will delay to stop while reactivation temperature up to 60
℃ ,
ensur ing that the water vapor s and heat can be completely removed.
• Reactivation heater
. The controller acquire signals from the heating temperature
transmitter, then PID adjusts internally, adjust s the power of SCR to ensure the
wheel is in constant temperature, to allow better energy saving.
•
The p rocess ed air outlet can be connected to an other air treatment equipment
according to the user needs.
The slow rotation of wheel is realized through the motor and belt transmission
device. Belt is located at the wheel rim, driven through the drive motor pulley.
Belt tension device can ensure belt in the appropriate firmness, prevents belt
slide and to deal with driving devices are in correct operation. The front panel
can be open to check the wheel rotation direction.
Motor overloaded and short circuit protection: Processing motor, reactivation
motor and the motor of wheel are introduced the overload and short circuit
protection function.
Stop protection ： W hen dehumidifier stops normal ly , reactivation fans (including
wheel) will continue to run until reactivation heater cools down to 60 ℃ below.
5.5 ZEOLITE ROTATION
• The centrifugal fan (or EC Centrifugal fan) is high quality . Τ he rotor blades and
the spiral case are made of steel. They are high ly efficien t , providing big air
supply and at the same time low noise levels.
