Esencor

ESENCOR, the copper tube of the third millennium. The ideal choice for supplying drinking water, for heating systems and for the distribution of gases and combustible liquids.

Characteristics

Manufactured with the most modern technologies available on today's world market, the result of scientific studies and tests that guarantee a considerably lower level of residual carbon than is required by the European manufacturing standard EN 1057, this copper tube is an excellent product against corrosion caused by the characteristics of waters present in water beds and in the public water mains.


Use and Directives

It complies with Presidential Decree no. 1095 of 3 August 1968, European Council Directive no. 98/83/EC, Decree no. 31 of 2 February 2001 and Ministerial Decree no. 174 of 6 April 2004 and is therefore suitable for use in the reception, treatment, transfer and distribution of drinking water.

Sampling plans during manufacture are applied according to the provisions of standard EN 1057 and guarantee the conformity of the copper tube on the basis of tests performed by the internal and independent laboratory that is part of the Corporate Quality System certified according to EN ISO 9001:2015.

The copper tube EN 1057 is marked СЄ as required by EU 305/2011 EU Construction Products Regulation (CPR).


*EN 1057 is the European reference standard on a continental level for the manufacture of copper gas and water tubes in water and heating applications. It establishes characteristics in terms of chemical composition, mechanical properties, dimensions and tolerances and the tests that must be carried out during production in order to manufacture a product that complies with specifications.
