Construction
2.3.1
Hull
•
compact stainless steel frame construction for corrosion resistance and effective insulation
against condensation
;
•
removable panels providing access to internal components
;
•
well-designed layout and selection of units to ensure minimum head drop
.
2.3.2
Conveying air circuit
•
at the air inlet there is a filter class G3 with the possibility of cleaning
;
•
centrifugal high efficiency low noise fan
.
2.3.3
Regeneration air circuit
•
at the air inlet there is a filter class G3 with the possibility of cleaning
;
•
centrifugal, high-efficiency, low-noise, forward-curved fan
.
•
heating section using PTC heaters
.
2.3.4
Rotor
•
The rotor is the main part of the dryer. Its characteristics directly affect the performance
and operation of the dehumidifier. The rotor is made of a special heat- resistant composite
material. The composite material is a corrugated structure filled with a highly effective
desiccant, forming many small air flow channels, contacting the air with a large area
and increasing the dehumidification efficiency
.
2.3.5
Rotor drive
•
Rotation of the rotor at the desired speed can be achieved using an electric motor
with a geared motor and a belt drive. The belt is located on the outer rim of the rotor
and is driven by a geared motor pulley
.
•
The belt tensioner maintains proper belt tension to prevent belt slip page. The direction
of rotation of the rotor and the condition of the belt need to be checked regularly
.
2.3.6
Safety devices
•
Motor protection against overload and short circuit: fan motors for working and regeneration
air, rotor drive motor have overload and short circuit protection functions
.
•
Shutdown protection: When the dryer is switched off under normal conditions,
the regeneration fan continues to run until the regeneration heater and rotor have cooled
below
60°С.
