GENERAL CHARACTERISTIC OF OFFERED SCREW AIR COMPRESSORS:

Offered by us screw air compressors are intended for continuous operating in heavy-duty conditions. They provide compressed air to various industry facilities in the following branches: marine, machine-building, electronical, wood, furniture, food, pharmaceutical and more.

Screw air compressors are modern, durable, low-noise, and energy-efficient sources of compressed air. Two-year warranty period covering all sub-assemblies is an evidence of their reliability. These compressors are featured with longer time between overhauls, easy operation and installation. Sound absorbing cases guarantee quiet operation, whereas owing to high-quality vibration absorbers there is no need for special foundation while placing the machine on the floor.

In screw air compressors are applied screw air ends produced by acknowledged manufacturer.

Compressors can be also equipped with an oil/water heat exchanger.

Compressed air coming out of the compressor and then pumped into system is considerably cleaned. Oil content is lowered to 5 ppm by use of efficient oil separating system. Considerable amount of moisture is eliminated in aftercooler, being a standard part in our compressors.

These machines are characterized by full automatic operation including: star/delta start-up, full protection against overloading and against too high oil temperature as well as indication of excessive oil and suction filter pollution.

To make control over compressed air production easier compressors over 22 kW are equipped with microprocessor controllers as a standard. The main task of the microprocessor controller is a continuous supervision over compressor's work to enable access to all work parameters. Moreover, the controller makes it possible to carry out permissible changes.

Each machine is equipped with a standard compressed air connection making it easy to install the compressor. Air cooling function allows to heat halls in the winter season with the use of warm air.

Compressors' structure, as well as safety and adjustment methods applied assure a totally safe work environment for the stuff and a safe machine operation. Maintenance information system is clear and easy to operate.

Every compressor produces heat while working. The amount of heat is comparable to the motor input power. All compressors in sound-absorbing casings make it possible to recover heat in the form of a warm air jet.

The heat thus produced can be used to heat rooms. It is possible to recover up to 80% of heat. As an option, our compressors can be equipped with an oil-water exchanger, which makes it possible to heat water. In this case, it is possible to recover ca. 70% of heat. The selection of a type of heating is performed automatically. If hot water is not collected, the compressor automatically switches to air-cooling.

Screw compressor in casings are not onerous in terms of noise levels. All casings are lined with a special noise-absorbing material, whose average sound absorption capacity is 80%. In addition, smaller compressors have specially designed inflow and outflow channels for cooling air which additionally reduce noise levels. Thanks to that, compressors can even be placed directly in a workshop if such a need arises.
