LN₂ Cleanroom Fogger Procurement Specification
A vague RFQ—“need LN₂ fogger for large cleanroom”—invites mismatched proposals. A strong specification tells suppliers what must be demonstrated and what information must be contractually controlled.
RFQ fields
- Application, governing standard and evidence objective
- Room/enclosure dimensions and operating state
- Required architecture or permission to compare
- Minimum acceptable output, runtime and final-outlet visibility method
- Number and size of outlets; hose and accessory configuration
- LN₂, water and electrical requirements
- Physical dimensions, weight and cleanroom transport route
- Safety, training and service documentation
- Warranty duration and exclusions
- Worldwide shipping, Incoterms, duties and destination requirements
- Factory and site acceptance criteria
- Lead time and spare-parts availability
Acceptance evidence
Require a revision-controlled product sheet, manual, configuration schedule and agreed test method. If output is a critical contract term, define where and how it is measured. If visible distance matters, define humidity, air velocity, camera and endpoint.
Commercial source of truth
The signed quotation and accepted configuration should override stale website copy. Save the controlling documents with the asset record and validation package.
