A procurement manager holding three offers at similar figures faces a question the comparison table does not answer: which of these was actually built around my facility?
Choosing a paint booth supplier is not settled by the catalogue maximum. It is settled by what the supplier asked you before quoting.
The first question: did they start from you or from a model?
A supplier who offers a model before asking the dimensions of your largest part, your site area and your available electrical capacity is selling what they hold rather than what you need.
The correct order is documented: a built-to-order booth starts with a site survey and a fixed internal size, then configuration sign-off before manufacture.
| Question | What it reveals |
|---|---|
| Were you asked the largest part’s size and weight? | Whether the offer was built on your part or a model |
| Was a site survey carried out? | Whether access, supply and clearance were calculated |
| What is the supplier’s published delivered range? | Real capability limits rather than promises |
| Is filtration stated by class? | A verifiable commitment or a vague phrase |
| What does the warranty cover in writing? | What you actually hold after handover |
| Are spare parts available locally? | Downtime at the first failure |
| Is a written specification issued? | Whether it can go into a tender document |
Filtration is stated by class, not by adjective
“High quality filtration” cannot be compared. Stated by class it can: stop, pre and ceiling filtration at EU3, EU4 and EU5, extending to three-stage bag and high-efficiency filtration at ≥98% where the work requires it.
A published range exposes the limits
Ask for the delivered range rather than a theoretical maximum. Ours runs from 3000 to 24,000 mm long, 3000 to 20,000 mm wide and 2650 to 6000 mm high, with heat output from 200,000 to 600,000 kcal/h and power from 11 to 50 kW.
A supplier without a published range is hard to compare, because every figure they give belongs to one project rather than to a delivery record.
After-sales is part of the offer
Spare parts, maintenance schedules and lead times are discussed with the specification rather than after installation, because a stopped chamber stops work rather than a machine. Manufacturer warranty with its term and conditions is defined in the quotation.
Frequently asked questions
What is the single most useful question to ask?
“What are the dimensions of the largest part I will coat, and how did you build your offer around them?” The answer immediately reveals whether the offer was built on your facility or on the supplier’s stock.
How do I compare two offers written differently?
Standardise the inputs rather than the outputs: send both parties the same part dimensions, the same coating material and your target throughput, then compare what comes back. The differences are then real.
Should I ask for a written specification before signing?
Yes. We issue written technical specifications with the required conformity data so they can be inserted directly into a competition or contract without redrafting — which is what makes comparison possible at all.
What gets forgotten in comparisons?
Three things: service clearance around the chamber, the supply capacity actually available after the workshop’s other loads, and local spare parts availability. All three appear after installation rather than before.
