ZPU JOŃCA Sp. z o.o.
A diffusion barrier along the entire length of the pipeline
Winner of many awards and honors


Our company in 2005-2007 was qualified as a supplier of heating pipes for large European customers, such as German Vattenfall, Italian AES Turin and Milan, Dutch ENECO. We have also gained the recognition of important organizations and technical institutes - for example: the French CSTB, the German MPA-Hannover. This has always been done by passing a series of tests and tests for products and checking the requirements of the quality control system. 

Despite the above recognition, the expansion of foreign sales, gave rise to the need to extend the qualifications of our products to applications with a larger number of recipients, without going through long-term research for separate end customers. Such possibilities are given to product certification by EuroHeat & amp; Power, stating compliance of products with EN253 and EN448 standards and strict quality control. Euroheat & amp; Power is an organization and a lobby whose members are the largest producers of heat and products for heating. It unites 24 organizations in individual countries as well as service providers and producers as well as renowned research centers from 32 countries.

The certificate issued by EHP is recognized and recognized by all recipients of heating products in Europe and other countries, such as Canada.

The process of applying for the EuroHeat & amp; Power began in April 2008, by submitting
in the EHP's Brussels headquarters of our application.

The next step was the selection of a research institute, we decided on the most prestigious Swedish Institute of Technical Research from Gothenburg..

The first phase of the tests was to subject the generic analysis of our samples to a laboratory in Sweden - aging tests, physicochemical properties analysis, among others:

  • PEHD shielding pipes
  • PUR foam
  • pre-insulated pipes
  • fittings

An important and important element of the EHP certification control was the inspection of our Plant made by representatives of the Institute of Technical Research from Gothenburg..

Planned activities ensure:

  • The production process was controlled at many angles of compliance with the requirements of the above mentioned standards as well as strict EHP requirements
  • Wybrane w sposób losowy z naszego składu magazynowego produkty sprawdzano w szczegółowej kontroli
  • The products selected randomly from our warehouse stock were checked in a detailed inspection
  • The quality control system was thoroughly analyzed

As a result of many tests and analyzes, a report was issued at the end of November 2008, highly evaluating the quality of our products. The immediate effect of the positive opinion was the issue of the EuroHeat Power Certificate in December 2008

This certificate requires annual control tests, which will be carried out with the same meticulousness, which will ensure the highest quality of our products.
