External Roof Mounted
There are three EcoCooling
Evaporative Cooling Systems
- ECP Plastic
- ECM Metal
- ECI Large Industrial
All systems utilise the same
electrical control systems and utilise Munters CelDek filter pads.
Methods of installation are shown
The method of fitting is dictated
by a number of factors which can only be ascertained during a
detailed site survey.
- Roof access
- Roof construction
- Availability of services
The coverage of an area may be
either complete or spot cooling
Complete coverage is achieved by
arranging the air distribution around the area. Spot cooling can
take the form of a single cooler in an area or directing the flow
of air down natural corridors in a building between the heat
The diagram below shows examples of
how air flows can be introduced into a work area. The
left hand diagram shows a complete
coverage by interleaving the air flows. The other two show how the
air is directed between the machines to where the people are
normally working. The hot
air naturally rises from the
machines and is normally extracted at high level.
The cool air naturally falls and
fills the spaces between the machines.
The diagram above shows how a ECP
unit is installed on a conventional sloped roof. The weight of the
unit is supported by the ductwork which in turn is supported from
the structural steelwork of the building. The cool air is
distributed using a 8-way plenum. Normally the input of the units
is balanced with an extract system to provide an appropriate level
of positive or negative pressure within the building. Extraction
control can be easily linked to the evaporative cooler controls.
It is preferable
to discharge the cool air as low as possible and extract the
warmer air from the highest practical point in the building.
Great care must be taken to ensure a weather proof installation
There are two
options for the discharge point from a ECSS Cooler:
This allows a
number of installation methods to be used
Once again the
building pressure would normally be balanced with an
appropriate level of extract.
The internal suspended system is one of the simplest
stainless steel plenum chamber is manufactured with laser
cut louvres which allows great flexibility in air
The flow rate of
the units must always be matched by the ventilation otherwise
the relative humidity of the building will rise
Internal Unit Mobile
The internal mobile unit is a
stainless steel constructed cooler designed to be both portable
Units can either be top or side discharge. They are normally
connected to a permanent water supply and a permanent drain. A
single phase 10A 240 V electrical supply is required.
Adequate ventilation must be
provided. This ventilation must equal or exceed the throughput
of the units to prevent a build up of humidity which can lead
to both loss of efficiency and discomfort.
