Qingdao Conqinphi Environmental Technology Group Co., Ltd., a leading manufacturer established in 2015 with a factory spanning 10,000-30,000 square meters and over 200 skilled employees, proudly presents the Double Four-Effect Evaporator constructed from premium 316L stainless steel. This automatic system delivers an impressive 800 L/H evaporation capacity at 220V 50Hz, designed to optimize energy efficiency and operational simplicity for industrial liquid concentration and wastewater treatment. With a decade of export experience exceeding US$10 million annually, our evaporator embodies reliability and innovation.
The core design leverages a four-effect evaporation principle that significantly reduces steam consumption compared to single-effect systems. Each effect is meticulously engineered with 316L material to resist corrosion from acidic or saline solutions, ensuring long service life even in harsh environments. The automatic operation is managed by a PLC-based touch screen controller, allowing operators to set parameters, monitor real-time data, and adjust processes with minimal manual intervention. This eliminates human error and enhances consistency.
Key Features & Technical Specifications
- High Thermal Efficiency: Four-effect design recovers latent heat, reducing energy consumption by up to 60% compared to single-effect units.
- Premium 316L Material: Excellent resistance to chlorides, acids, and alkalis, ideal for pharmaceutical, chemical, and food industry applications.
- Fully Automatic Control: Touch screen interface with PID control for temperature, pressure, and liquid level; supports remote monitoring via optional IoT module.
- Compact Footprint: Vertical or horizontal configuration available, saving valuable floor space in your facility.
- Easy Maintenance: Modular design allows quick access to heating tubes and separators; CIP cleaning system optional.
- Wide Capacity Range: Standard model at 800L/H, with custom capacities from 200L/H to 5000L/H available upon request.
| Parameter | Specification |
|---|---|
| Evaporation Capacity | 800 L/H (water basis) |
| Number of Effects | 4 (Double Four-Effect configuration) |
| Material of Construction | 316L Stainless Steel (all wetted parts) |
| Power Supply | 220V 50Hz, 3-phase (other voltages available) |
| Operating Temperature | 80°C – 120°C (adjustable) |
| Control System | PLC + HMI touch screen, automatic level control |
| Dimensions (approx.) | 6000mm x 2500mm x 3500mm (customizable) |

The automatic operation significantly reduces the need for continuous supervision. The system can self-adjust based on feed concentration and flow rate, ensuring consistent output quality. Moreover, the 316L material guarantees compliance with stringent hygiene standards required in food and pharmaceutical industries. The energy-saving design translates into lower operating costs, typically achieving a steam economy of 0.25-0.3 kg steam per kg water evaporated, which is superior to traditional three-effect units.
We understand that every application is unique. Therefore, our team offers customization options including different voltages (e.g., 380V 60Hz), additional corrosion-resistant coatings, explosion-proof configurations for solvent recovery, and integration with existing MVR systems. Our engineering support is available from concept to commissioning, ensuring seamless installation.

Frequently Asked Questions
-
Q: What is the difference between a double four-effect and a standard four-effect evaporator?
A: The term "double four-effect" may refer to two parallel four-effect trains operating together, effectively doubling the capacity while maintaining thermal efficiency. Our standard configuration is a single four-effect unit with 800L/H capacity; please contact us for clarification on your specific model. -
Q: Can this evaporator handle high-viscosity liquids or slurries?
A: Yes, the 316L material and forced circulation design (optional) allow processing of fluids with viscosity up to 1000 cP. For higher viscosities, we recommend a scraper-type or falling film evaporator. -
Q: What maintenance is required for the 316L evaporator?
A: Regular inspection of tubes for scaling, cleaning of separators, and checking of seals. An automatic CIP system is available for chemical cleaning without disassembly. We recommend a preventive maintenance schedule every 6 months. -
Q: Is the system suitable for corrosive chemicals like hydrochloric acid?
A: 316L has good resistance to dilute hydrochloric acid at room temperature, but for concentrated or hot HCl, we recommend higher-grade alloys like Hastelloy. Please provide your chemical composition for a material recommendation. -
Q: What is the typical energy consumption in kWh per liter of evaporated water?
A: For a four-effect evaporator, the steam consumption is about 0.25-0.3 kg steam per kg water. Electric power for pumps and controls is approximately 0.02-0.04 kWh per liter, depending on feed conditions. -
Q: Can the control system be integrated with a DCS or SCADA?
A: Yes, our PLC supports Modbus, Profibus, and Ethernet/IP communication protocols. We can provide an OPC interface for seamless integration with your existing control system. -
Q: What is the lead time for this evaporator?
A: Standard lead time is 30-45 days after order confirmation, depending on customization. Rushed orders may be expedited for an additional fee. -
Q: Do you offer rental or leasing options?
A: Yes, we provide rental units for short-term projects or pilot tests. Please contact our sales team for terms and availability.
