Nature has
an old but efficient way of humidifying and cooling
air:
Evaporation of water |
|
| This simple, yet most efficient, law of nature has
been used by Munters in evaporative cooling systems
since the 1950s. When air moves over a water surface
it causes some of the water to evaporate. This evaporation
results in a reduced temperature and an increased vapour
content in the air. The bigger the area of contact between
the air and water the more evaporation occurs resulting
in more cooling and addition of moisture. Munters have
improved the efficiency of the process, by designing
new contact media of air and water to interact. The
fill and the contact materials used are intended to
provide the greatest possible surface area in the smallest
possible volume, and to permit the passage of air through
them with the least possible pressure drop. The range
of Humicool products evolves from these materials called
CELdek and GLASdek. |

| Cooling of Greenhouses |
|
| Many plants grow poorly
in high temperatures. Yet, the temperature in
a greenhouse can be up to 15 degree C higher than
the ambient temperature outside. Thus, in most
cases, some form of cooling is required to cool
the inside of the greenhouse to improve the quality
of the plants. The cheapest form of cooling the
air is by means of natural evaporation of water
into the air stream. As was explained in our introduction
Munters Celdek pads magnify this process, thus
increasing the cooling efficiency. Celdek evaporative
pads are used widely in cooling of greenhouses.
With Celdek the evaporation takes place solely
at the pads without the water being introduced
into the greenhouses in liquid form (droplets).
Water is distributed over the pads via a low pressure
distribution system without the need of nozzles.
These factors gives evaporation cooling with Celdek
the following benefits: |
|
- Cheap, effective cooling without risk of excessive
droplets of water damaging plants and creating uncomfortable
working conditions.
- Labour saving - not having to clean spray nozzles.
- Only low pressure pump required.
- The water distribution system also creates a self-cleaning
mechanism, thus minimising clogging. It also has
the benefit of removing some of the dust from the
air entering the greenhouses.
We can supply the Celdek pads with or without the water
distribution system (Cooldek) to be installed on the
wall of greenhouse separately from the fans or we can
supply a packaged unit (Horti-cool) incorporating the
pads, water distribution system, pump and fan. |
