CELdek® 7090- 15 / Rder& 7090- 15 evaporative cooling pad is used
in systems where high efficiency cooling is required. It can be
used for many different cooling purposes but is particularly
suitable for cooling of live stock buildings and greenhouses when
higher air velocity is required.
The Green stripe pad consists of specially impregnated and
corrugated cellulose paper sheets with different flute angles, one
steep (45 deg) and one flat (15 deg) that have been bonded
together. This unique design yields a cooling pad with a high
evaporation efficiency while still operating with a very low
pressure drop. In addition scaling is kept to a minimum and no
water carry-over occurs due to the fact that the water is directed
to the air inlet side of the pad. This is where most of the
evaporation takes place.
The impregnation procedure- for the cellulose paper ensures a
strong self supporting product, with high absorbance, which is
protected against decomposition and rotting and therefore
increascing longevity.
The distribution pad constitutes a vital part of a complete system
and should always be ordered in combination with Rder& evaporative
cooling pads. Placed on top of the cooling pad it ensures a uniform
supply of the water to the cooling pad and minimises the risk of
dry spots.
The evaporative cooling technology
Water is circulated through a pump station and supplied to the top
of the cooling pad via a distribution manifold. A distribution pad
on the top of the cooling pad ensures an even water distribution.
The water flows down the corrugated surface of the Rder&
evaporative cooling pad.
Part of the water is evaporated by the warm and dry air that passes
through the pad. The rest of the water assists in washing the pad,
and is drained back to the pump station through a gutter system.
The heat that is needed for the evaporation is taken from the air
itself. The air that leaves the pad is therefore cooled and
humidified simultaneously without any external energy supply for
the evaporation process. This is natures own cooling process.
Equipment
High evaporation efficiency
Superb wetting properties
Low pressure drop when wet, leading to lower operating costs
No water carry-over
Low scaling
Self cleaning
Strong and self supporting
Long life time
Low running costs
Quick and easy to install
Environmentally friendly
Consistant high quality
Performance curves: The pressure drop diagram shows the
pressure-drop over the pad in the wet condition. With the pad in a
dry condition the pressure-drop is <10% less. There for there is
minimal loss of air-flow when the pad is wet compared to when it is
dry.
