NORRES CP PE 457 EC
Electrically conductive PE hose for ATEX and ventilation – CP PE 457 EC
CP PE 457 EC is an extra-flexible, electrically conductive polyethylene hose for ATEX zones and industrial use. The construction with a galvanised steel spiral and conductive wall makes it suitable for ventilation, extraction and transfer of dust, powders, fibres and chemical vapours in potentially explosive atmospheres.
Flexibility and safety for industry
This hose offers compressibility up to 4:1, strong resistance to acids/alkalis and excellent chemical resistance. Temperature range: −35 to +80 °C. Ideal for industrial extraction, chemicals, ventilation and process plants with Zone 22 requirements.
Approved for ATEX zones and ESD control
CP PE 457 EC has electrical and surface resistance <103 Ω and is approved for the aspiration of combustible dust (Zone 22), and for gases and vapours (Zones 0, 1, 2) as well as chemical ventilation. The hose complies with ATEX 2014/34/EU and German TRGS 727.

If the required dimensions are only listed as “production length”, the minimum order quantity is 150 metres per order.
Positive and negative pressure values are recommended operating limits. Bending radius is measured on the inside of the hose bend. Subject to technical changes. All values determined at 20 °C and are approximate.
