Industrial spare parts for Lausanne and the region
What sits behind the quench has to survive wet and alkaline duty; what sits on the district heating flow either takes 175 degrees continuously or does not. A wrong call is therefore not a parts error but an unplanned outage. The material entry for it stands here at the position, priced in francs.
Your train, stage by stage
The operating values tell you which material is a candidate at all
In the middle of Lausanne a waste-to-energy plant runs whose operating values are known across the whole train: boiler at 400 degrees and 50 bar, district heating flow at 175 degrees, around 113 kilometres of network with over 1,300 building substations, combined heat and power efficiency above 50 per cent.
Anyone looking after such a train reads the material question straight out of those values. What a quotation round supplies is a price — what they need is the operating limit, and that usually arrives only on request.
Here it comes first: material, pressure and temperature limits and design on all 114 articles, the franc price beside them, both without an account.
- Over 1,300 building substations on around 113 kilometres of network
- New municipal treatment works on 70,000 square metres, commissioning planned for 2026
- Full-text search across the specification table, not only the product name
Six stages, six material questions
Where on this train which part wears out
All operating values come from the operator plant documentation. The third column maps which product group wears at each stage.
| Stage | Operating value | Where the wear occurs |
|---|---|---|
| Boiler | 400 degrees at 50 bar | Seals, valves, condensate handling |
| Two-field electrostatic precipitator | 45,000 volts | Seals and feed-throughs in the dust section |
| Quench and caustic scrubber | Wet, alkaline section | Material resistance in seals and valves |
| Reheat | to 250 degrees | Heat exchanger fittings, expansion take-up |
| DeNOx catalyst and continuous analyser | Continuous duty with explicit reference to OPair | Sample gas coolers, filter elements, water separators in the sample path |
| District heating flow | 175 degrees, around 113 km of network | Over 1,300 substations with valves and seals |
Beside the framework agreement
The line item missing from the contract is what shukchok is for
shukchok is an open marketplace for industrial goods — several suppliers, one basket, duty paid across the border. Demand in Lausanne is concentrated on two large operators, and they buy through framework agreements. That is not competition but a division of labour: the agreement covers the plannable volume through price lists and named contacts, and that part keeps running there.
Beside it sits the demand no contract foresees — the line item missing from the contract, the part in a design the stores do not hold, the demand arising from a conversion. The new municipal treatment works on 70,000 square metres generates exactly that second kind for years.
And the range is not limited to what sits in it today: manufacturers and distributors list their own programme here free of charge, so the product groups along this flue gas and district heating train grow with the suppliers who join.
- Visible franc prices without a login, a specification table on all 114 articles
- One checkout across several manufacturers — a maintenance round becomes one transaction
- French interface; legal texts and PDF documents in German and English
