Spare and wear parts for plant operators in Utrecht
You cannot connect more capacity here until 2029, so the plant you have is not an asset any more — it is a maintenance contract with itself. On shukchok every one of its replacement intervals carries a price before you sign in.

Your situation on site
One delivery address, four maintenance calendars
Almost everything heavy in Utrecht stands on one estate — 308 hectares net, around 900 businesses, more than 19,000 employees, and the only zoning in the city that reaches environmental category 5.2.
Four firing plants, four flue gas paths, four sampling points — and a grid congestion that blocks new heavier connections until 2029. You do not build here; you rebuild and run the plant longer than planned. Every extra service year is another inspection, another change interval, another part bought against a specification.
And a retrofit list is the worst thing to put through a quotation round, because it grows during the shutdown. Here the price stands above the specification table before you sign in, and the whole list goes into one basket across manufacturers.
- Material, operating limits and design at all 114 articles, in eight languages
- Purchase order number and cost centre as cart fields, both on the invoice

What the marketplace changes
A retrofit list is not a bill of materials. It grows while you work.
shukchok is an open marketplace for industrial goods, inside the same customs territory and the same currency as you. A project has a bill of materials, a budget and one decision. A retrofit has none of that: a list that grows during the shutdown, a mix of manufacturers, and an internal recharge to whichever cost centre owns the plant. Three unglamorous things carry that — the cart fields for purchase order number and cost centre, which need no login and reach the invoice; one basket across manufacturers in one ordering pass; and the purchase history at the article for anyone signed in.
That last one answers the question half of all reorders stall on: is this the same part as last time? And the more manufacturers and dealers list here, the more often the whole growing list stays in one basket instead of breaking into five separate orders. A supplier missing from it is one invitation away.
- A whole earlier order back in the basket in one step
- One ordering pass, one contracting party — contract, payment and refund sit with us
What that looks like in the cart today:
- Net price and specification without an account, on all 114 articles
- Purchase order number and cost centre as cart fields, without a login
- One basket across manufacturers, one ordering pass
- Purchase history and one-step reorder once you are signed in
- A quotation as a PDF from the account: running number, 30 days, priced server-side

For suppliers
A frozen grid means a long service life. A long service life is a parts market.
Plant that runs past its planned life buys more inspections, more change intervals and more parts against a specification. If you make or distribute filter elements, separators, traps, safety valves, seals or bellows, the estate above is concentrated demand behind one gate — four firing plants, one delivery address.
Getting a range onto that shelf costs nothing, and that is the model rather than a promotion: our margin comes out of a position that sells, and out of nothing else. And where a retrofit asks for the documented scope — an inspection certificate to EN 10204, a calibration certificate, a PED category at the article — that comes from the suppliers who hold those papers anyway; on an open marketplace they store them as article metadata instead of building a shop of their own.
- No listing fee, no monthly fee, no manual product approval
- Certificates and category travel with the article as metadata
- Contract, invoicing, payment and refund handling stay with us
From the retrofit desk
Three questions a shutdown list raises
Can I filter by material or nominal size?
Is there a volume discount for a whole shutdown list?
How does the free shipping threshold work from the Netherlands?
The range behind it
Categories for firing plants and hot process equipment
Two ways in
Run the plant longer, with the right part in hand
Specification before the order, net price without an account, and your purchase order number on the invoice. And if you manufacture or distribute yourself: shelf space here comes without a listing fee.
