Double effect evaporator price manufacturers

When selecting a double effect evaporator, the primary focus should be on the Steam Economy Ratio, which typically allows for saving approximately 40-50% of steam consumption compared to single-effect units. Buyers must verify the Heat Exchange Area (m²) and ensure the Material of Construction (MOC) is appropriate for their fluid; for corrosive substances, Grade 316L Stainless Steel or Titanium is essential. Additionally, confirm the Evaporation Capacity (kg/h) matches your production scale and check for Automatic PLC Control Systems to ensure stable vacuum levels and temperature gradients.

For cross-border procurement, ensure the equipment complies with ASME (American Society of Mechanical Engineers) Section VIII for pressure vessels or the PED (Pressure Equipment Directive) for the EU market. If used in food or pharma, the unit must meet GMP (Good Manufacturing Practice) and FDA standards, featuring CIP (Clean-In-Place) systems and high-grade surface polishing (Ra < 0.4μm). Always request Pressure Vessel Hydrostatic Test Reports and Material Traceability Certificates (MTRs) before shipment.

The price is primarily driven by Material Grade (SS304 vs SS316L), the Total Heating Surface Area, and the Level of Automation. A fully automated system with Siemens or Schneider components will command a premium but reduces long-term labor costs. Furthermore, the inclusion of peripheral components like Condensers, Vacuum Pumps, and Feeding Pumps in the package price significantly impacts the total investment. Buyers should look for Modular Skid-Mounted Designs which, while potentially higher in initial cost, drastically reduce On-site Installation and Commissioning expenses.

Double effect evaporators are widely used in the Chemical Industry for wastewater treatment (Zero Liquid Discharge), the Food & Beverage Industry for concentrating juices or dairy, and the Pharmaceutical Industry for herbal extraction. For high-viscosity liquids, ensure the supplier offers a Forced Circulation design rather than a Falling Film design to prevent Tube Fouling and Scaling, which can lead to frequent downtime and increased maintenance costs.

To secure your investment, utilize Trade Assurance services on Made-in-China.com to protect your payment until delivery. It is critical to hire a Third-Party Inspection Agency (such as SGS or BV) to conduct a Pre-Shipment Inspection (PSI). This inspection should include a Dimensional Check, Weld Quality X-ray (if applicable), and a Functional Test Run to ensure the equipment meets the agreed-upon technical drawings before it leaves the factory.

Focus negotiations on the Warranty Period and Spare Parts Package. Request a 24-month warranty instead of the standard 12 months, and insist on a 'Wear-and-Tear' kit (including gaskets, seals, and sensors) to be included in the price. For bulk or high-value orders, negotiate Milestone Payments: typically 30% deposit, 60% after successful FAT (Factory Acceptance Test), and 10% retention after successful commissioning at your facility.

Due to the size and fragility of heat exchanger tubes, specify Seaworthy Vacuum Packaging and Steel Frame Crating to prevent corrosion and structural damage during sea transit. Ensure the contract defines Incoterms clearly (FOB or CIF). For oversized effects/columns, confirm if they require Flat Rack or Open Top Containers, and verify that the supplier provides a detailed Loading Plan and Center of Gravity Diagram to prevent accidents during unloading at your site.
