Hot thermal coatings - HVOF, plasma coatings


Žiarové nástreky sú zamerané hlavne na ochranu povrchov. Povlaky aplikované žiarovým striekaním zohrávajú kľúčovú úlohu vo výrobe a renovácií.

We offer services in field of dip coatings. We use the latest technologies for application dip coatings:

We using HVOF and plasma system with ABB robots of German company Thermico GmbH & Co. KG.

Precision Coating is achieved by positioning device and a turntable in cooperation with robots ABB 4600. Positioning device allows us to very accurately applied surfaces with a diameter up to 1100 mm and lengths up to 3080 mm at a speed of 6-300 rpm / min.


Pumps / Mechanical seals / Packing



We are dedicated to servicing mechanical seals and pumps in harsh operating conditions. Given the complexity of the problems of mechanical seals and requirements of our customers was generated application and service group that seeks by professional installation and supervision eliminate seal failure due to improper installation. These are workers who are highly specialized on this issue and achieve very good results (see references). Furthermore, this group is secured operative intervention in case of emergency.



We place great emphasis on the mechanical strength, chemical resistance and environmental integrity of our products.

We provide a wide range of gaskets for equipment operating in environments with different chemical and thermal requirements. We offer a complete range of seals, mechanical seals, knitted gland packings, graphite gaskets, PTFE products, other gaskets and maintenance products.


Water jet - Water jet cutting


We offer comprehensive services in the field of cutting by water jet. Cutting of materials is done by 5 axis water jet SUPREMA

The technology of water jet cutting of materials uses abrasive action of high pressure water jet, which acts on the material. This leads to an abrasion material, high pressure jet, carrying out a separate material.

The water jet of company Chetra SK is equiped by 5 axis 3D evolution cutting system.

Renovation of valves


We offer services in the renovation of fittings. We are renovating industrial valves using modern technologies. Rebuild damaged fittings that were exposed to heavy chemicals, high temperatures, corrosion, friction, cavitation, abrasion erosion or other challenging conditions.

For a longer lifetime of renovated fixtures are applied dip coatings. The company has the most advanced technology in the field of thermal spraying and to increase the life applyies various types of nanoHVOF coatings and plasma coatings.

The renovation of valves is made for customer from reason, that renovated valves is more advantage form price perspective like a new one.

We are providing repairs of industry fitings CSN EN 12569 (133065)
