Particle-free energy chains are required to guide cables and hoses safely in cleanrooms. igus developed the e-skin flat, a modular design, a cost-effective alternative to ribbon cables. In the Fraunhofer cleanroom test, the energy supply system has proved its freedom from particles in accordance with ISO Class 1 not only as a single-layer, but also as a three-layered ready-to-connect energy chain system.

Cleanrooms around the world in which LEDs, microchips, and semiconductors are manufactured are characterised by little space and the absence of particles. In order to guide cables safely in compact installation spaces, igus has developed the e-skin flat. Cables and hoses can be quickly installed into the flat profiles and replaced during maintenance.

igus uses a special high-performance plastic that has been regularly tested in the in-house cleanroom laboratory throughout the entire development process. The e-skin flat is resistant to wear and abrasion, and its single-layer variant has been Cleanroom Class 1 since its introduction in 2019. The invention also won over the 2021 REINER! Awards judges. "Since the e-skin flat is rarely installed with just one layer, but often with three, we wanted to achieve the highest cleanroom class here” says Peter Mattonet, cleanroom technology industry manager at igus GmbH.

The Fraunhofer Institute IPA therefore tested an e-skin flat energy supply system with three layers of four chambers each, including support chains, cables, and hoses. During operation, the testers checked emissions at three key points. In the test, the chain was the only cleanroom energy chain to receive ISO Class 1 according to ISO 14644-1 with a bend radius of 70 millimetres. "The e-skin flat stands out as a particle-free, compact energy supply system for the cleanroom, that saves the user space and therefore greatly reduces costs," says Mattonet.

CFCLEAN provides a ready-to-connect system

The e-skin flat energy supply system is configurable depending on the application scenario. It can consist of up to six chambers per layer. Three-layered structure supports chains in the lowest layer which ensures chain stability. igus has also developed the CFCLEAN series specifically for use in the e-skin flat. The cable cores can transmit energy and signals for motor control, bus, and Ethernet. The user can receive, upon request, a complete cleanroom system that is certified and ready to connect right away.
