View SpecificationsIn modern process industries, the necessity for high-efficiency concentration equipment has transcended basic manufacturing productivity to become a core pillar of global sustainability, carbon reduction, and zero liquid discharge (ZLD) requirements. Multi-effect evaporators represent a vital thermodynamic strategy, utilizing the latent heat of vapor generated in one effect to heat the subsequent effect operating under a lower pressure. This cascading thermal economy dramatically cuts utility costs while handling substantial liquid streams.
Across Europe, North America, and East Asia, manufacturers face stringent environmental and energy directives. Regulatory alignment—specifically under directives like the European Pressure Equipment Directive (PED) and general CE certification protocols—is no longer an optional benchmark but an operational mandate. Choosing a certified CE Multieffect Evaporator supplier ensures that structural engineering, materials traceability, safety interlocks, and pressure vessels conform to demanding global compliance standards. This mitigation of operational risk is coupled with substantial cuts in carbon output, making advanced evaporation plants central to corporate Environmental, Social, and Governance (ESG) strategies.
Historically, increasing the number of effects in an evaporation array offered a linear progression of steam efficiency at the expense of system footprint, complexity, and capillary control challenges. Today, thermodynamic modeling software allows manufacturers like Jiangsu Zongheng to optimize thermal flow sheets, balancing capital expenditure (CAPEX) with operational expenditure (OPEX). Incorporating features such as Thermal Vapor Recompression (TVR) or Mechanical Vapor Recompression (MVR) within a multi-effect matrix yields unmatched flexibility, permitting high concentration ratios even for highly viscous, fouling-prone, or heat-sensitive materials.
Specifically engineered for low-temperature operation on heat-sensitive solutions. Liquid flows down the internal walls of the tubes as a thin film, facilitating high heat transfer coefficients. Excellent for juices, pharmaceutical broths, and volatile organic compounds.
Designed for liquids prone to salting, scaling, or high viscosities. High-speed recirculation pumps maintain continuous velocity through the heat exchanger tubes, preventing boiling on the heating surface and suppressing scaling tendencies.
The pinnacle of environmental efficiency. It recycles latent heat by using a mechanical compressor (centrifugal or roots blower) to raise the temperature and pressure of the evaporated vapor, which is then fed back to heat the raw liquid, eliminating live steam consumption during steady-state operation.
In many corn processing, alcohol, and starch factories, large quantities of waste steam, dryer vapors, and low-temperature hot water are vented or lost. Jiangsu Zongheng design engineers excel in custom integrating waste heat evaporators into existing plants. By utilizing drying vapor as the primary heat source for a multi-effect concentration system, plants can recover valuable process water, concentrate steep liquors without additional live steam, and achieve near-zero carbon emission increases for the concentration process.
Industrial wastewater and pharmaceutical broths often contain aggressive components such as chlorides, organic acids, and variable pH agents. Standard steels fail rapidly under these conditions. Our manufacturing plants utilize advanced metallurgies, including Titanium (Gr. 1, Gr. 2), duplex steels (S32205, S32750), and high-alloy stainless steels (316L, 904L), under strict ISO9001 and ASME welding compliance. Precision tube-to-tubesheet joint expansion, automatic orbital welding, and thorough radiographic testing guarantee reliable operation over decades.

The convergence of industrial automation, smart sensor technology, and thermodynamic optimization defines the next era of chemical process plant design. As a specialized CE-certified manufacturer, Jiangsu Zongheng is actively developing integration pathways to transition static multi-effect systems into dynamically responsive smart utilities. Our engineering team focuses on three key future development fields:
Industrial scale and crystalline build-up inside the tube bundles are the primary drivers of thermal efficiency degradation. By introducing real-time continuous calculations of the Overall Heat Transfer Coefficient (U-value) across individual effects, our upcoming software suites can automatically flag early fouling stages. Integrating this data with automated variable frequency drive (VFD) controls on recirculation pumps allows the system to adjust internal velocities, dynamically mitigating deposit formation before scaling shuts down the line.
Discharging raw industrial brine or highly concentrated sludge into municipal treatment systems is becoming increasingly unfeasible. The future standard is a hybrid concentration loop. By combining pre-concentration Falling Film Evaporators, intermediate Forced Circulation Concentrators, and finishing Solid Dewatering devices (such as the Zongheng Single Screw Press), plants can recover up to 98% of clean process water. This water is then ready to be recycled directly back into the steam boiler loop or the main production line.
As corporations shift away from fossil-fueled steam boilers, modern multi-effect evaporators must be ready to work with alternative heat sources. We are currently testing systems that utilize electric boilers, heat pumps, and closed-circuit recompressors designed to run entirely on green power grids. This technical pathway ensures that the equipment you purchase today remains compliant with future zero-emission mandates decades down the line.
CE Certification ensures the equipment complies with European directives on safety, health, and environmental protection. For industrial evaporators, this specifically means compliance with the Pressure Equipment Directive (PED 2014/68/EU). It guarantees that calculations, material sourcing, structural welding, and safety release valves are manufactured to withstand severe operating pressures without risk of failure, offering verified safety reassurance to operators worldwide.
A falling film evaporator relies on gravity to distribute liquid downward as a thin film on the inner surfaces of heated tubes, ensuring rapid heat transfer and a short residence time—ideal for heat-sensitive liquids. A forced circulation evaporator uses high-capacity recirculation pumps to force the liquid through heat exchanger tubes under pressure, preventing boiling within the tubes to suppress scaling. This makes it perfect for viscous fluids, high-solids crystallization, and materials prone to scaling.
Yes. By capturing hot exhaust air, low-pressure flash steam, or drying vapor from equipment like tube bundle dryers, a waste heat evaporator can function as the primary thermal source for the initial effect. This strategy reduces the need for fresh utility steam, turning heat waste into an efficient recovery cycle.
Depending on the chloride levels, pH, and temperature of the process fluid, Zongheng manufactures evaporators using 304/316L stainless steel, Duplex stainless steel (S32205, S32750), Hastelloy, or Titanium (Grade 1 or Grade 2). Full material traceability reports (MTR) are provided in accordance with ISO9001 and ASME specifications.
Key maintenance tasks include periodic Clean-in-Place (CIP) cycles to remove scale deposits, checking and recalibrating temperature and pressure sensors, verifying the alignment and mechanical seals of circulation pumps, and inspecting pressure relief valves. Dynamic monitoring of heat transfer efficiency helps optimize these maintenance schedules, minimizing unplanned downtime.
