Silmet S.p.A.

CONDY, the copper tube ideal for transporting cooling gases. It is supplied with caps at the ends to retain the high level of cleanliness of the internal surface required for installation.

The particularly well-designed coating is made from very low-density closed cell expanded polyethylene and guarantees an excellent resistance to the spread of water vapour with the resulting reduction in the formation of humidity on the outer surface of the tube

The coating is odourless, non-toxic and made without the use of CFC. Its external surface is corrugated giving further mechanical protection. It is classified as class 1 fire resistant and is suitable for use in plants with operating temperatures ranging from -80°C to +98°C.

The CONDY copper tube is supplied in 50-metre coils marked at intervals also indicating the relative meters.

The core of the CONDY is the SILMET copper tube manufactured according to the European standard EN 12735-1 and with a level of internal cleanliness that also complies with standard ASTM B280.

Packs cannot be stacked.
For packs with a larger diameter (h 220 x Ø 90 cm) a maximum of 2 are loaded side by side onto a pallet together with a third smaller pallet
The others can be loaded side-by-side in threes.
