ZW1 and ZW2 compliance certificates

The electric sets of wagon heating couplings which we offer have a special ZW1 certification, which can  be found in the first annex. The certificate was granted by the Electrotechnical Institute in Warsaw. Moreover, these products have been certified in the Czech language. Owing to this, the product has been of interest to the foreign market companies from the rolling stock industry.
