Closed energy chain for dirt and swarf protection

Closed energy chain for dirt and swarf protection

In harsh environments, cables require special protection against dust, swarf, dirt and other external influences. The best protection is provided by the closed energy chain from igus - also known as energy tubes or e-tubes.

Typical industries and applications: Material handling, woodworking machinery, in all areas exposed to dirt and swarf ...

What are closed energy chains?

Compared to open energy chains (diagram 1), closed energy chains (diagram 2) are completely closed. Closed energy chains made of the igus material igumid G can be used at temperatures up to +120°C and those made of the material igumid HT for hot swarf up to +850°C. Laboratory tests and numerous references have made igus closed energy chains a safe cable protection for welding robots and machine tools for over 20 years. Discover below the best closed energy chains that protect cables from dust, dirt, sludge, compost, wood, textile fibres, paper dust, grinding paste, coolants, glass dust, glass splinters, coal dust, sand, etc.
