304 Stainless Steel Forced Circulation Evaporator With PLC Control System
Product Spotlights
As a leading manufacturer with over 8 years of experience, Qingdao Conqinphi Environmental Technology Group specializes in providing robust and efficient evaporation solutions. Our 304 Stainless Steel Forced Circulation Evaporator with PLC Control System is engineered for demanding industrial applications where reliability, precise control, and high-quality construction are non-negotiable. We combine premium materials with advanced automation to deliver a system that optimizes your concentration, crystallization, or solvent recovery processes, ultimately enhancing your operational efficiency and product quality.
This evaporator is designed to handle a wide range of feed materials, including heat-sensitive, viscous, or fouling-prone solutions. The forced circulation mechanism, driven by a high-flow pump, ensures rapid movement of the liquid across the heating surface, minimizing scaling and maximizing heat transfer efficiency. Coupled with an intelligent PLC system, it offers unparalleled control over critical parameters, leading to consistent output and significant energy savings.
Core Product Features & Technical Advantages:
- Superior Material Integrity: Constructed primarily from high-grade 304 stainless steel, offering excellent corrosion resistance against a wide spectrum of chemicals, ensuring longevity and maintaining product purity.
- Enhanced Heat Transfer: The forced circulation design creates high liquid velocity, which drastically improves the heat transfer coefficient and reduces the tendency for scaling or fouling on heat exchanger tubes.
- Fully Automated Operation: The integrated PLC control system automates the entire evaporation cycle, including start-up, operation, cleaning-in-place (CIP), and shutdown sequences, reducing manual intervention and human error.
- Precision Process Control: Real-time monitoring and adjustment of temperature, pressure, flow rate, density, and liquid level ensure optimal and repeatable process conditions for every batch.
- Energy Efficient Design: Features like multi-effect configuration (optional), thermal vapor recompression (TVR), or mechanical vapor recompression (MVR) can be incorporated to significantly reduce steam consumption.
- Scalable & Customizable: Available in a wide range of capacities, from laboratory/pilot-scale units to large industrial systems, with options for different heating sources, separators, and condensers to match specific process needs.
- User-Friendly Interface: The Human-Machine Interface (HMI) touchscreen provides intuitive operation, data logging, alarm management, and remote access capabilities for supervisory control.

Frequently Asked Questions (FAQ):
Q1: What are the main advantages of a forced circulation evaporator over other types like falling film?
A: Forced circulation evaporators excel with viscous, fouling, or crystallizing products. The high-velocity pump circulation prevents solids from settling on heat transfer surfaces, reduces scaling, and provides superior handling of difficult fluids compared to gravity-dependent designs.
Q2: Is 304 stainless steel suitable for my application involving chlorides or acidic solutions?
A: While 304 stainless steel offers good general corrosion resistance, for environments with high chloride content or low pH, we often recommend and can construct critical components from 316L stainless steel or other specialized alloys upon request to ensure durability.
Q3: How does the PLC system improve operational efficiency?
A: The PLC automates control loops, sequences, and safety interlocks. It allows for precise set-point control, data logging for process optimization, alarm management for early fault detection, and can enable remote monitoring, leading to higher productivity, consistency, and reduced operator workload.
Q4: Can this evaporator be integrated into our existing production line?
A: Yes, absolutely. Our engineering team designs systems with integration in mind. We can provide interfaces for connectivity with your existing SCADA, ERP, or control systems and ensure proper piping, electrical, and control integration.
Q5: What kind of after-sales support and services do you offer?
A: We provide comprehensive support including detailed installation manuals, startup supervision and commissioning by our engineers, operator training programs, and ready availability of spare parts. Remote technical support is also available.
Q6: What is the typical lead time for a custom-designed unit?
A: Lead time varies based on complexity, capacity, and customization level. Standard models may have shorter lead times, while fully customized large-scale systems require detailed engineering and fabrication. We provide a project-specific timeline upon finalizing the technical proposal.
Q7: Are energy-saving options available for this evaporator?
A> Yes, several options exist to enhance energy efficiency. These include designing a multi-effect system, incorporating Thermal Vapor Recompression (TVR) or Mechanical Vapor Recompression (MVR), and using heat exchangers for feed pre-heating. We analyze your process to recommend the most economical configuration.
Q8: Do you provide pilot-scale units for testing?
A: We do offer pilot-scale or skid-mounted test units. This allows you to conduct trials with your actual feedstock at our facility or yours to confirm process parameters, final product quality, and evaporator performance before committing to a full-scale investment.
