compressed air dryer system

Quote coordination for a compressed air dryer system starts with a shared assumption list. Compressed Air Dryer Sourcing is an independent sourcing partner. We circulate the same peak flow, inlet pressure, hottest inlet and ambient temperatures, dew-point location, quantity and destination so factory wholesale quotes can be compared. We do not shortlist plants as already audited, and we do not convert a catalog scfm into a process guarantee. Filters, drains, purge or regeneration energy, shipping, training and commissioning stay included or excluded only when a supplier writes them down.

Service stage and responsibilities

Sample trial

Comparable compressed air dryer system quotes collapse when one bidder prices a refrigerated circuit without cooling-water data and another prices a regenerative pair without naming purge air. The details below are the coordination questions we repeat. They are not a claim that any named factory has already been inspected for this buyer. Tooling in this cluster means filter housings, drain valves and any bypass manifold that ships with the skid, not a cutting die.

Sample trial: Sample run
Buyers should state peak inlet flow, inlet pressure, maximum inlet temperature, ambient temperature, oil class, required pressure dew point and where that dew point will be measured at peak demand. Electrical supply (voltage, phase, frequency), cooling water if a refrigerated circuit is used, footprint, quantity, destination and the requested delivery window belong in the same brief. Optional budget with currency and per-unit or whole-order basis may be attached; it is a buyer preference, not a verified market index. Premium, mid-range and budget-friendly labels describe documentation depth and spare-kit preference, not a rating this office has verified.
Site readiness
Each supplier should mark corrected capacity at the stated hottest condition, list filter and dryer pressure losses included in the offer, and say whether purge air or regeneration energy is inside the operating figures. Automatic drains, pre-filter and after-filter housings, and bypass valves should appear as included or extra. Installation, condensate piping, cooling-water tie-in, electrical landing, operator walkthrough and SAT dew-point logging remain open until named. FAT at the supplier and SAT with the plant compressor running belong to whoever the purchase order names; this desk does not perform those tasks.
Owner acceptance
Typical gaps are missing hottest-condition data, unsigned drain routing, unspecified dew-point tap, and purge energy treated as free. Those deviations stay open until the named supplier answers; this desk does not close them by inventing scfm or dew-point class. Engineering acceptance remains a contract matter between buyer and supplier. No existing quotation is required to submit an RFQ. We will request factory quotes using the same written assumptions so differences in filters, shipping and commissioning become visible instead of hidden in a single lump sum.

Which assumptions must suppliers quote for a compressed air dryer system? Corrected capacity at the buyer’s worst-case inlet and ambient temperatures, the dew-point measurement point, included pressure losses, and whether regeneration energy is inside operating figures. Adjacent compressors and receivers stay outside unless listed. See hottest-condition sizing notes before treating catalog flow as universal.

Mark included versus extra lines on every compressed air dryer system quote

Ask each factory to split the skid from site work so purge energy, drains and shipping do not hide inside a lump sum.
