04. Structure of the dehumidifier

.
Housing framework. made. from. welded. galvanised. steel. section . .
Double-layer.panel.elements.with.sound.or.heat.insulation,.approx . . 30.
mm.thick . . The.panel.are.set.airtight.into.the.frame.construction.and.
are.removable.on.the.operating.side . . All.housing.parts.are.resistant.to.
temperature.and.moisture . . The.operating.side.is.designed.such.that.all.
maintenance.work.can.be.carried.out.without.a.problem .
Rotor (drying wheel; sorption unit)
The.dehumidifier.is.equipped.with.a.patented.silicate.rotor . . The.rotor.
is.composed.of.layers.of.flat.and.corrugated.non-woven.fabric.made.
of.chemically.bound.silica.gel.and.metal.silicate . . This.creates.a.large.
number.of.axially.aligned.air.ducts.with.a.large.surface.area.and.a.
direct.connection.to.the.internal.void.structure.of.the.silicate . . This.ena-
bles.good.transition.of.the.water.vapour.and.allows.for.the.unusually.
high.degree.of.adsorption.of.the.silicate.rotor .
Due.to.the.special.production.process.of.the.material,.the.silicate.is.not.
destroyed.by.saturated.air . . The.dehumidifier.can.therefore.be.operated.
with.pre-cooling . . Even.the.failure.of.the.heating.or.of.the.air.stream.for.
regeneration.does.not.cause.damage .
Accumulated.dust.on.the.rotor.surface.can.be.removed.with.water.if.
the.rotor.is.saturated . . Oily.deposits.can.be.cleaned.using.solvents.or.a.
non-alkaline.detergent .
Due. to. the. fixed. bonding. of. the. silica. gel. to. the. substrate. material,.
no.sorbent.is.carried.out.with.the.air.stream . . Even.when.the.rotor.is.
at.a.standstill.there.is.no.over-saturation;.therefore,.no.special.safety.
precautions.are.necessary . . The.rotor.has.a.high.mechanical.strength.
and.is.not.combustible .
The.rotor.is.driven.by.a.geared.motor.via.a.toothed.belt . . A.tension.
spring.prevents.the.toothed.belt.from.slipping,.as.well.as.preventing.
B - B - 6 5
overloading.of.the.motor . . The.function.and.correct.direction.of.rotation.
can.be.checked.at.any.time.through.the.sight.glass .
The rotor bearing consists.of.a.temperature-resistant.stainless.steel.
axle.and.plain.bearing .
The rotor is sealed by. a. floating. ring. seal. with. automatic. com-
pensation . .
The process air fan and regeneration fan are.implemented.as.sin-
gle-sided.sucking.radial.fans,.with.an.impeller.installed.directly.on.the.
motor.shaft . . Three-phase.standard.motor,.IP54,.ISO.F .
The regeneration air heater is.implemented.as.an.electric.element.
heater . . It. is. constructed. from. individual. chrome/nickel. heating. ele-
ments . . The.individual.heating.elements.are.electrically.connected.to.
form.3.heating.stages .
alternatively:
implementation.as.galvanised.steel.steam.heater . . The.steam.and.con-
densate.connections.are.fed.airtight.out.of.the.housing.and.provided.
with.flange.and.counter-flange .
Thermostats function.as.overheating.protection.and.safety.tempera-
ture.limiters .
In.order.to.protect.against.unacceptably.high.operating.temperatures,.
a.safety.thermostat.and.a.maximum.temperature.limiter.are.mounted.
at.the.air.inlet.and.outlet.of.the.regeneration.air.heater .
A.temperature.limiter.is.mounted.in.the.regeneration.air.exhaust.and.
functions.as.a.rotation.monitor .
The control cabinet is.located.on.the.top . . The.indicator.lamps.and.
switches.are.installed.in.the.service.doors . . Refer.to.the.circuit.diagram.
in.the.appendix.for.the.individual.electrical.functions .
