Cooling water hose EPDM

for wastewaterEPDMfor railway application

Overview
Hose designed for cooling systems, wastewater and sewage handling in rail vehicles and rail industry applications.

Applications

• Cooling water and coolant circuits on rail vehicles
• Heating systems
• Roof drainage and condensation drainage
• Railroad cars and rolling stock
• Sanitary installations on board

Flow medium

• Standard cooling water with common additives (normal concentrations)
• Condensate
• Sewage and excrements
• Treated and untreated cooling water

Inner lining
Non-porous, smooth inner surface for reduced fouling and improved hygiene.

Further properties
Inner layer electrically conductive, R < 10^6 Ω/m; transition resistance through the hose wall R > 10^11 Ω; outer layer electrically insulating, R > 10^11 Ω/m; Complies with fire and smoke gas toxicity standard DIN EN 45545-2 HL3 (requirement set R22 + R23).

Temperature range
From -40 °C / -40 °F up to +95 °C / +203 °F.
