Gaskets
Felt gaskets of the type: NF-PES-LE 0.32 grey are inserted in
normal temperature rotors. The felts shall be pushed as close
as possible towards the storage medium while direct abrading
has to be prevented. Felts are pressed by manufacturer but
may change their position due to transport.
Attention: Check felts and gaskets prior to initial operation and
lay on the felts when the fans are operating.
Ball-bearings
The ball-bearings used are of low-maintenance and designed
for an operating lime of 100.000 hours. Generally, they can be
used for temperatures of up to +120°C (+248°F).
Under normal operating conditions maintenance is not
required.
Driving motor
Rotary heat exchnagers are equipped with threephase current
backgeared motors for 3 x 380 / 220 Volt with thermal
protection contacts at 140°C (284°F). Should the rotors be
delivered without wiring, the motor is always star-connected. In
connection with the controllers KR 4/ KR 7 the motors have to
be run in triangulated wiring connection 220 Volt and
connected thermal protection contacts! Otherwise warranty is
excluded.
The motor may easily be mounted at another edge of the
device in case mounting shows that the location is not
suitable. Under normal operating conditions the motor does not
require maintenance (gearing with lifelong grease lubrication).
Attention: Special motors for e.g. enamelling lines with oil
filling (opening at the top).
Controll
For this see corresponding controller instructions (attached to
the controller).
Final inspection by manufacturer
Final inspection by the manufacturer is confirmed by a yellow
label being attached at the inside of the inspection door.
Among others, the completeness of the delivery (with special
regard of the rotor control and its components) is confirmed. In
case of questions we´d ask you to indicate the corresponding
inspection number / date and the respective rotor size and
number.
The rotor size and number are indicated on the rating plate
which is attached at the outside of the inspection door. It is
additionally imprinted in the frame of the inspection door.
Assembly
Assembly of the rotor has to be done on a horizontal surface.
The exact rotor fitting position is determined by the designation
"Abluft" (exhaust air). This mark at the rotor frame corresponds
to the inlet side of the exhaust air. In case of horizontal rotors it
has to be observed, however, that the circumferential support
frame incl. middle frame is needed. The respective sketch may
be ordered. Diagonal flow of the rotors has to be avoided
because the rotor mass may be driven by the air stream. If
necessary install guiding plates.
Connections of conduits
· Inlet of forces through the connection conduits into the
frames of the rotary heatexchangers has to be prevented.
· Fixing of the rotor ist the best by drilling screws. -
· For insprection works the rotor has to be accessible within
the installation.
· The rotors are designed for countercurrent operation supply
air / exhaust air. If this is not the case we´d expect
consultations.
· Direct current operation leads to a considerable decrease in
performance. In addition, danger of soiling is increased.
