Water Technique


Ultrafiltration provides the mechanical treatment of surface waters (rivers, lakes, etc.) and fresh waters (wells, drilling, etc.) by membrane filters.

The strength of this technology allows water to be clarified and de-contaminated from all particles, bacteria, germs, viruses, algae, pollen, parasites, organic molecules up to 0.01 micron without chemical treatment and with a relatively low power consumption.

The raw water is filtered under pressure through a microporous membrane which conserves the natural minerals in the water, which guarantees constant and impeccable quality, respecting the environment and the well-being of the population.


Reverse osmosis (also known as hyper-filtration)

Reverse osmosis stops all molecular contaminants, bacteria, viruses, germs, pollen down to 0.0001 micron without treatment by toxic chemicals. Salts, including sea salt, are also eliminated.

Reverse osmosis is a common method for treatment and de-salination of seawater, lake water, saline and turbid waters . The filtration is done with a multilayer membrane which filters water at high pressure. This type of membrane is also used for the treatment of fresh water containing chemical contaminants which are not eliminated by ultrafiltration membranes , such as fluorine or arsenic.

The membrane pores being very small, they only allow water molecules (H20) to pass through. No salt remains. Drinking this water regularly is not recommended as there is a risk of de-mineralizing the human body. It is necessary therefore to re-mineralize the water at the outlet of the membranes, for example, by adding calcium. In addition to re-mineralizing, the Craft ® machines add a pH corrector.

Reverse Osmosis & microfiltration

Our expertise in the purification and filtration of water allows us to offer turn-key equipment sized to measure, responding perfectly to the needs of our customers and to the on-site conditions .

EM Medical Solutions

Our guarantee for the Medical World

The bottled oxygen production units with a diaphragm compressor(s) represent our flagship product, having proved themselves by offering unequalled resistance and continuous production of high quality oxygen, no matter what the conditions of use.

The diaphragm compressor provides high volumetric efficiency guaranteeing optimal production. Its electrical consumption and its noise level are low. There is limited maintenance and this is done at relatively spaced intervals, from 8,000 to 14,000 hours of production.

The diaphragm compressor unit has two stages for pure oxygen production. The compression is obtained by the elastic deformation of metallic diaphragms squeezed between two stainless steel plates. The oxygen is never, therefore, in contact wit a moving part which could produce dust (piston, etc) no with any lubricant. Purity is thus, rigorously guaranteed.

EP Industrial Solutions

Our industrial and military solutions

Craft® offers an oil-free, 3-stage compressor with pistons. This type of compression is particularly suitable for industrial and military applications with a flow rate of 6 Nm3/hour.

Less costly than a diaphragm compressor, the piston compressor requires maintenance every 1,500, 2,500 and 4,500 hours of production.

Water solution

Our custom WATER solutions

By working in close collaboration with Craft Engineering, the original manufacturer, you have the guarantee of the best choice, that which you deserve.

Craft ® installations are supplied, if need be, from the supply pump right to the drinking water tank, with all the connections required for the distribution of quality drinking water.

Renewable energy solutions responding to the latest technologies are also available.

Diaphragm compressors

We have developed a range CPO – EM benefitting from a diaphragm compressor specially designed to continuously provide optimal quality oxygen.

While we offer other types of compressors, we have always considered that the diaphragm compressor was the only one capable of use in the hospital environment. Other than the compression, the service container guarantees the proper ventilation of the system and provides a noise barrier which is highly appreciated within a hospital.

Our GAS Solutions

Craft® Engineering

Since1986, Craft® is a 100% Belgian concept.

Assembled and adjusted in our premises by our engineers, the quality of our units of production is assured. It was Marc Boulle who, first had this idea when in 1986, he received an order for the RDC. The Craft experience was born. By associating it with a container, the machine could thus be easily transported everywhere, and having the advantage of operating with the doors closed, it was sheltered from the weather, pilfering and intrusion.

Concerned for the environment


Our units are veritable on-site autonomous micro-plants

The gas production units are completely integrated into an ISO container, just like our water purification units which can also be supplied on skids, depending upon the model.


Certain of our units are specially designed for lasting use in an extreme tropical environment.

Respecting the environment, they are designed to operate in an unequalled manner and depending upon the ranges, inextreme environments or on isolated sites.

GAS technique

PSA Technique

The production of oxygen is based on PSA (Pressure Swing Adsorption) technology. This system allows ambient air to be dissociated into oxygen and nitrogen by molecular filtration.

By far, the easiest to implement, the molecular filtration technique required no specialized qualifications. Furthermore, it is the best adapted to difficult environments (high temperature, humidity, dust, altitude, etc.) where it has shown its great resistance.

Ambient air, pre-filtered then compressed by an air compressor, passes through a filter which eliminates any traces of oil or impurities before being sent to a dryer and lastly a buffer tank. From there, the pure, dry compressed air arrives into the generator where it is dissociated on the one hand into nitrogen and on the other into oxygen by the adsorption-desorption cycle operated by a molecular sieve. The oxygen thus produced is then sent into an oxygen compressor in order to fill high pressure bottles.
