Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The number of stages typically ranges from 3 to 6. More stages increase thermal efficiency, but the optimal number depends on the specific process requirements and economic considerations. Verify the exact configuration with the manufacturer.
Wetted parts are typically made of stainless steel such as 316L (ASTM A240), while non-wetted parts may use carbon steel. Specialty alloys are used in corrosive zones. Confirm material selection for your specific application.
By using vapor from one stage as the heating medium for the next, the train reduces overall steam consumption. Specific steam consumption is typically 0.3 to 0.6 kg steam per kg water removed, but this depends on the number of stages and operating conditions.
Key parameters include evaporation capacity, number of stages, operating pressure and temperature, heating surface area, outlet concentration, steam consumption, electrical power, footprint, and weight. Always verify these values with the legal manufacturer or supplier for your specific model.
