The ECOLAB Energies
ECOLAB Energies is a company
specialized in the design and manufacture of "OASIS"
pumping windmills. Founded as a small family firm in 1927, ECOLAB
Energies and its five-men team build their
models with the same enthusiasm that it showed more than 70
years ago. Backed by strong tradition, the firm takes special
care to exploit the experience it has acquired while also
making use of new technologies in order to constantly improve
the efficiency of its windmills.
Today, more than 20,000 models have been sold in countries
at every latitude, ranging from temperate areas (Europe) to
the tropics (West Indies, Madagascar, etc.) and equatorial
zones (Black Africa).
They have demonstrated their efficiency and durability in
every type of climate.
Supported by our know-how, you can adapt our product
ranges according to the specific requirements of the
locations where you wish to site them and of their intended
uses in order to solve:
- climatic problems
- problems related to the lie of the land
- pumping problems
Thanks to the specially engineered reliable and robust
design, the "OASIS" pumping windmill allows you to
perform pumping operations in an efficient and durable manner
for all types of applications:
- irrigation of crops
- village pumping facilities
- oxygenation of ponds
- fish farming
- maintaining of game stocks by creating watering
- livestock rearing
The performance levels of windmills depend on a number of
factors, the main ones being the following:
Flow rates can vary from 500 litres to 15,000 litres per
hour, depending on the model selected. "OASIS"
pumping windmills are capable of pumping as much as 60 metres
on the discharge side and 6 metres on the suction side.
Pumping to a depth of 100 metres can be provided after
carrying out a specific case study.
The pumping mode - suction or discharge - depends on the
method of pump installation:
- vertically above the well, either of these two modes
can be used,
- at a maximum distance of up to 100 metres from the
well, only suction mode can be used (assuming that
the height difference is no more than 6 metres).
In recognition of our know- how, "OASIS"
windmills have passed tests conducted by CWD (Consultancy
Services Wind Energies for developing countries) as a result
of which they were chosen for a large-scale windmill
programme in Mauritania: the ALIZES programme. Currently,
more than 250 windmills are in service in this country
The "OASIS" windmill is supplied
in kit form in several packages. Each model comprises the following standard items:
- A wheel equipped with a drive head comprising 15
blades of galvanized sheet metal. Their specially
adapted curvature, studied in wind tunnel tests,
ensures that the windmill operates even at very low
wind speeds of less than 3 m/s. The rotating motion
of the wheel is converted into vertical reciprocating
motion on the windmill head by means of a crank and
connecting rod system. This motion is transmitted to
the pump piston by the linkage bolted onto the
bearing neck at the base of the connecting rod.
- A tower made up of steel angles treated with a coat
of rustproof paint or by hot galvanizing to ensure
very long-term protection. A suction and discharge
piston pump (range of 40 mm to 140 mm) comprising a
brass cylinder, a bronze piston, two flanges and 3 or
4 tie rods.
The materials used must be selected according to the
water quality. It may be necessary to equip some
installations with stainless steel parts. (Please consult us).
- A rudder to keep the wheel facing into the wind and a
feathering blade. This assembly is articulated so as
to ensure that the windmill is set to safety mode in
case of gusts with a wind speed of more than 9 m/s or
storms. In these circumstances, the windmill's
rotational speed does not exceed 80 rpm.
- Pumping accessories: a bronze strainer, a bleed valve
to be fitted on the piping at a height of 20 cm above
ground level in order to avoid problems with freezing.
Plus the equipment specific to each installation:
small or large radius elbow, outlet tee junction, etc.
- This operation can be carried out by the customer
with the help of an explanatory manual (one day's
work for two people). Our technicians are ready to
give advice by telephone at all times.
- A network of approved independent installers is also
at your disposal. (Please consult us for details).
It is essential to comply with maintenance recommendations
in order to ensure the correct operation and long service
life of these machines. Maintenance is carried out with the
windmill stopped and consists of just the two following
- greasing of bearings (once or twice a year).
- bleeding of piping in case of freezing conditions. .
A stuffing box can be installed in the well to allow
pumping to be continued during the winter without any
problems with freezing.
The ground stop device designed to facilitate maintenance
work is supplied as optional equipment. This device is
recommended as an easy means of preventing problems due to
freezing and drying-out of the well.
