Conti develops drinking water hose for railway industry

ERJ staff report (LMH)

Hanover, Germany - ContiTech said its long-lasting and highly flexible Aquapal hose fulfills all statutory requirements for the transport of drinking water and is approved by Deutsche Bahn AG, the German rail company.

For the preparation of meals and drinks on board trains, as well as for washing up glasses and crockery - water for human consumption is subject to the stringent guidelines of the European drinking water directive, ContiTech noted. The hoses used to fill drinking water tanks must also be approved for drinking water and labelled accordingly.

The German technology company noted that its Aquapal DB is specially tailored to the everyday conditions on board trains. It has been tested in accordance with KTW “pipework” guidelines, DVGW-W270 and DVGW-VP 549, and is approved for transporting water. Deutsche Bahn AG has also approved it as a drinking water hose.

Conti said the fabric reinforcement made from hard-wearing synthetic thread makes the hose highly flexible and kink-resistant, and means that it can withstand being driven over. The inner lining of the branded hose is completely neutral in terms of taste and odour - one of the most essential features of drinking water hoses. The Aquapal DB hose can also withstand temperatures from -20°C to +90°C. It can be steam cleaned at up to 130°C, ensuring that it can be cleaned appropriately.
