1. Technical Information.
1.1 Machine identification data
Machine identification data is shown on the
warranty sheet supplied to the customer and is
enclosed in the documentation and on the
machine identification plate.
1.2 Introduction
During the summer to improve the internal
environment within a production unit, warehouse
or other area, it is necessary to ventilate the
area with frequent changes of fresh, filtered and
possibly cool air. For large areas such as
industrial buildings, an air conditioning plant is
not practicable due to the large volume of air to
be cooled and the thermal loads of processes to
be neutralized, requiring very high energy load,
plus the cooling effect is reduced by the exhaust
air extraction plant and frequent opening of
doors during normal activity.
Evaporative cooling plants that cool the air using
a natural principle represent an optimal solution:
air passes through special wet water filters,

losing part of its heat during the evaporation
process of the water and hence lowering the air
temperature. The absence of refrigeration plant
reduces energy consumption to a minimum and
enables large volumes of air to be treated.
