Condensate separation

During the process of compressing the atmospheric air and during its filtration and drying, the formation of condensate takes place. It is an inevitable and natural side effect of these processes. Condensate is an aggressive mixture of water, oil and other pollutants that has a negative impact on the environment. Pursuant to the regulations in force (Journal of Laws No. 116 of 5 November 1991), condensate containing more than 15 mg / l of oil cannot be discharged into the sewage system.

In order to avoid the high costs associated with the disposal of all condensate by external companies, it is worth considering treatment of the condensate at the place of its formation. It is a more convenient and, above all, much more economical solution.

In our offer you will find a wide range of separators and condensate drains from two market-leading companies: Atlas Copco and BEKO with nominal flows of devices generating compressed air from 17 to over 4,400 l / sec.

The selection of the appropriate water-oil condensate separator must be made on the basis of appropriate parameters, such as:

• compressed air temperature and relative humidity of atmospheric air at which condensate accumulates,
• the type of oil used in the air compression process,
• climatic zone in which the device operates.

In general, the lower the temperature of the compressed air and its relative humidity, the less condensate accumulates in the compressed air.

The process of condensate separation itself consists in its initial dilution and pre-filtration in the tank where the condensate is collected. The condensate thus prepared is then filtered through filters including a final filter containing an activated carbon bed. The condensate filtered in this way is discharged by gravity into the sewage system, without any negative impact on the natural environment.

Condensate drain

Condensate accumulating in the process of compression and treatment of compressed air must be removed, because it has a very negative impact on the durability of the equipment and the quality of the final product. For this purpose, we offer condensate drains: mechanical and electronic.

Both types of drains automatically remove condensate from the compressed air.

Mechanical drains are mainly installed under compressed air expansion tanks, under filters, cyclone separators and on compressed air installations.

Their biggest advantage is the simplicity of operation, low purchase cost and no need for electric power supply. However, you should always remember to periodically maintain them and clean the float.

The second category of condensate drains are electronic drains, which also automatically remove condensate from the compressed air. Electricity is essential in this process. These drains may have a time setting that allows you to set how many and for how many times the valve is to be opened for draining the condensate. Unfortunately, it also involves the release and loss of a certain amount of compressed air. Therefore, the best proposition for electronic condensate drains are Bekomat devices by BEKO and Atlas Copco - EWD series.

These drains are equipped with intelligent systems for measuring the amount of condensate in the tank and their discharge using the minimum amount of compressed air. Bekomat and EWD drains are available for oil and oil-free condensate (very aggressive condensate). They are available for pressures up to 16, 25 or also up to 40 bar. The type and model of the condensate drain is selected by the amount of condensate it can collect from the device it is to work with, e.g. dryer, filter, cyclone separator, expansion tank.

There are special models of Bekomat condensate drains dedicated to cooperation with cyclone separators or filters, they additionally have the function of monitoring and managing the filter cartridge to which they were connected.

An additional advantage of electronic condensate drains type Bekomat, through optional equipment, is the possibility of its operation in sub-zero temperatures, where the standard drain would freeze, and therefore would not fulfill its functions. Electronic, float condensate drains should also be serviced periodically - by replacing the seals or the service unit.

Electronic, automatic condensate drains facilitate the operation of the compressed air network and relieve us in the process of condensate removal from compressed air, which has a very negative impact on the operation of devices and the end product.
