Train parts washing tunnels

Our R&D team has developed a train parts washing tunnel for the SNCF.

Our customer had a triple problem for the washing of his parts of different volumes and masses:

• Have a tunnel for efficient washing
• Provide user security for tunnel usage
• Work with the recycling of very dirty water, in order to limit the consumption of water, product and energy

MONTANIER responded to the 3 issues by carrying out the following actions:

• Custom design of washing tunnels based on customer input data and MONTANIER experience for efficient washing
• Adaptation of the best safety measures for operators with the realization of a risk analysis in collaboration with APAVE
• Establishment of a treatment and recycling chain for washing water to save energy and consumption

In order to meet the needs of our client, we have created 2 small washing tunnels, with a side-by-side layout, in order to have a sufficient loading / unloading area.

The realization of 2 tunnels offered several technical advantages:

• Installation in the proposed area (20 mx 11.30 m).
• Immediately have the additional surface for loading and unloading the washing trays (50 m² +/-)
• Allow loading / unloading in masked time, during washing
• Ensure the preventive or curative maintenance of a tunnel by continuing the washing on the second tunnel
• Ensure a washing volume higher than the specifications.
• Each of the 2 tunnels washing a surface of Lg 5.20 mx width 3.10 m = 16.12 m² per 3h30 cycle, ie 32.24 m² per tunnel, ie 64.48 m² for the 2 tunnels per 8h00 shift.</li >
• For reasons of economy, the tunnels benefit from gas heating of the washing water.
