5. INDUS HIDROS Dehumidifiers For Cold Rooms - EH BT
Cold rooms dehumidifiers
EHBT low temperature dehumidifiers series are high-performances units
especially designed for low temperature cold rooms rooms where the
humidity level should be controlled during product storage treatment.
This series comprises 1 model which cover a capacity range of 84
l/24h.
EHBT units are designed for easy maintenance and service, each part
being readily accessible and, when required, easily replaceable thus
reducing service and maintenance costs.
All units are supplied with hot gas defrost system and antifreeze heater
on condensate drip tray, they are fully assembled and wired at the
factory.

7.  Humidity is the amount of moisture in the air. There are different
ways to express humidity. I will go over the two most common ways
which are the relative humidity and the dew point.

The relative humidity is the amount of moisture in the air as a
percentage of the most moisture that could be in the air at a certain
temperature. If the air has half the amount of moisture it could have
then the relative humidity is 50%. When it is raining or snowing and
the maximum amount of moisture has evaporated into the air then
the relative humidity will be at 100%. The relative humidity tends to
be highest in the morning since cooler air can not evaporate as
much moisture as warmer air. In weather forecasting, the humidity
aloft is often more important than the humidity at the surface. When
the relative humidity is 100% through a deep layer of the
atmosphere and air is rising then precipitation will occur. A relative
humidity above 80% will feel humid especially in mild or warm air. A
relative humidity below 30% will feel dry.

8.  Another popular expression of humidity is the dew point. This is
the temperature that the relative humidity will be 100% when air
is cooled. When air cools the relative humidity will increase. It
will continue to increase as the air cools until it reaching the
saturation point. Morning dew is common in humid places in the
morning. This occurs from air cooling to the dew point and
further cooling results in condensation. The temperature will
always be greater than or equal to the dew point. When the
temperature is equal to the dew point then the relative humidity
is 100%. The dew point is a good indicator for noting how dry or
muggy it feels outside. Dew points of 60 F or higher will feel
muggy. Dew points less than 40 F along with the temperature
greater than 70 F will feel dry. Dew point is a popular measure in
weather forecasting since it is used to be able to tell how much
moisture a storm could have. Warm and high dew point air will
produce storms when the atmosphere is unstable and rising air
occurs.

10.  Cooling the air - vapor condensation
 In a cooling system the humidity is reduced by cooling the air below dew
point. A part of the moisture in the air is condensed and drained out.
 In an adsorption system the humidity is reduced with an adsorbent
material as silica gel or activated alumina.
 Adsorption is a physical process in where.
 Moisture is condensed and held on the surface of the material.
 Without any change of in the physical or chemical structure of the
material. The adsorbent material can be reactivated by heat.

12.  Moisture will not condense on a surface if the
air in contact with it has a dew point lower
than the surface temperature. Hazards
directly attributed to condensation are
experienced in areas such as health &
safety, integrity of electrical
equipment, product quality, packaging and
material handling.

13.  Corrosion rate of iron and steel will be dramatically
reduced if the air in contact with the surface is maintained
below 50%RH - it is eliminated by reducing to
40%RH.Dehumidification is often more effective and less
expensive than conventional methods of preservation
(egg: surface treatments). Applications benefiting from
dehumidification include bridges, power stations, ships
(refit or lay-up), offshore constructions, aircraft and
military vehicles.

14.  The characteristics of electronic products can
change at high relative humidity - failure
rates also increase.
INDUS THERMAL SYSTEMS

15.  The quality of drugs, powders, dried food,
confectionery and other hygroscopic materials
can only be maintained during production if it is
kept in contact with air at a low relative humidity.
Most hygroscopic materials require dew-points
so low that this can only be achieved using
desiccant dehumidifiers.

16.  Introduction: Dehumidifiers regulate humidity
by removing moisture from the air, thereby
creating living conditions that are
inhospitable to dust mites, mold and other
allergenic organisms.

17.  Room dehumidifiers, like a PARKOO
Dehumidifiers work much like air conditioners;
warmer, moist air enters the dehumidifier and
then crosses refrigerant cooled coils, causing the
moisture in the air to condense on coils within
the machine. The moisture then collects in a drip
pan or bucket for disposal while the air is slightly
reheated before being discharged. The reheat
process is done by capturing and using heat
generated from the energy spent to cool the air.
By being slightly warmed, the air exiting the
dehumidifier is dry and warm - which means it
will attract moisture like a magnet and maximize
the dehumidifier's efficiency.
