EsencoRICEMedicaLLevel Wound CoilCoated
 

REFRY, the copper tube that is ideal for distributing cooling liquids and particularly suitable for building FAN-COIL heating and cooling systems. It is supplied with caps at the end for retaining the required high level of cleanliness on the inner surface  until its installation.

The particularly well-designed coating, made using low density, closed cell expanded polyethylene guarantees excellent resistance to the loss of water vapour with the resulting reduction in the formation of humidity on the external surface of the tube and complies with Law 10/91, former Law 373, concerning the design, installation, running and maintenance of thermal plants in buildings for the purpose of the control of energy consumption. 

The coating is odourless, non-toxic and made without the use of CFC. Its external surface is corrugated giving further mechanical protection. It has class 1 fire resistance classification and is suitable to be used in plants with operating temperatures from -30°C to +95°C.

The REFRY copper tube is supplied in 50-metre coils (25 metres for Ø 22 mm) marked at intervals also indicating the relative metres. 

The core of the REFRY is the ESENCOR copper tube, providing excellent protection against corrosion, the result of scientific studies and tests that guarantee a considerably lower level of carbon residue than is required by the manufacturing standards (EN 1057), with a level of internal cleanliness that complies with standard ASTM B280.
