Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – a trusted manufacturer with over 8 years of experience in designing and producing advanced environmental equipment. Our PLC Controlled Vacuum Evaporator-Crystallizer for High Efficiency 60°C Operation represents the pinnacle of low-temperature evaporation technology, specifically engineered to treat industrial wastewater with minimal energy consumption. By combining vacuum evaporation and crystallization in a single, automated unit, this system achieves up to 90% water recovery while converting dissolved solids into dry, manageable crystals. Whether you are dealing with RO concentrate, metal finishing wastewater, or chemical process streams, our evaporator-crystallizer offers a reliable, cost-effective solution for zero liquid discharge (ZLD) applications.
Built with precision and durability in mind, this equipment features a PLC-based control system that ensures consistent operation at a stable 60°C, significantly reducing scaling and fouling compared to traditional high-temperature evaporators. The vacuum environment lowers the boiling point of water, allowing evaporation to occur at a gentle 60°C – ideal for heat-sensitive liquids and reducing energy costs by up to 30%. Our unit is fully customizable to match your specific flow rate, space constraints, and automation requirements, making it a versatile choice for industries ranging from pharmaceuticals to food processing.
Key Features & Technical Specifications
- PLC Automation: Touch-screen interface with real-time monitoring of temperature, vacuum, feed rate, and crystal discharge. Full remote control capability via optional SCADA integration.
- Low-Temperature Operation (60°C): Minimizes energy consumption, reduces corrosion, and prevents thermal degradation of sensitive compounds. Ideal for heat-sensitive wastewater.
- Integrated Crystallization: Continuous or batch crystallization module produces dry, free-flowing crystals that can be collected and disposed of easily – reducing waste volume by up to 95%.
- High Efficiency Vacuum System: Multi-stage vacuum pump ensures stable operation under -0.08 to -0.095 MPa, achieving rapid evaporation rates.
- Corrosion-Resistant Construction: Main body made of SS304 or SS316L (optional), with PTFE-lined piping for aggressive chemicals. All wetted parts are fully compatible with acidic or alkaline streams.
- Energy Recovery Option: Optional heat pump or mechanical vapor recompression (MVR) module can further reduce operating costs by 40-60%.
- Compact Footprint: Skid-mounted design saves floor space – typical dimensions: 3m x 2m x 2.5m (for 100 L/h unit).
- Easy Maintenance: Modular design with quick-access covers for cleaning and inspection. Automatic CIP (clean-in-place) system available.

Frequently Asked Questions (FAQ)
-
Q: What types of wastewater can this evaporator-crystallizer handle?
A: It is suitable for high-salinity industrial wastewater, including RO concentrate, metal finishing rinse water, chemical process streams, pharmaceutical waste, and landfill leachate. The system can handle total dissolved solids (TDS) up to 250,000 ppm. For extremely corrosive fluids, we recommend optional Hastelloy or PTFE lining. -
Q: How does the 60°C operation benefit my process?
A: Operating at a low temperature (60°C) reduces energy consumption by up to 30% compared to traditional evaporators running at 100°C. It also minimizes scaling, corrosion, and thermal degradation, making it ideal for heat-sensitive liquids. The vacuum environment ensures efficient evaporation even at this low temperature. -
Q: Is the PLC control system easy to operate?
A: Yes, the system features a user-friendly touch-screen HMI with intuitive menus. Operators can monitor and adjust parameters such as feed rate, vacuum level, and temperature in real time. Remote monitoring and data logging are optional. We provide on-site training and detailed manuals. -
Q: What is the typical maintenance schedule?
A: Due to the low-temperature operation, cleaning intervals are typically 2-3 months. The system includes automatic draining and flushing ports. An optional CIP (clean-in-place) system can further reduce maintenance downtime. We recommend annual inspection of vacuum pumps and seals. -
Q: Can I customize the capacity or materials?
A: Absolutely. Our evaporator-crystallizers are modular and customizable. Standard capacities range from 50 L/h to 500 L/h per unit. Multiple units can be combined for higher throughput. Material options include SS304, SS316L, Hastelloy, and duplex stainless steel. We also offer different heating methods (steam, electric, or thermal oil). -
Q: What certifications does the equipment comply with?
A: Our products are manufactured in an ISO9001, ISO14000, and OHSAS18001 certified facility. We can also provide CE, ATEX, or other certifications upon request (subject to verification). The control panel meets UL/CE standards depending on the destination. -
Q: How long does the delivery take?
A: Typically, lead time is 30-45 days after order confirmation, depending on customization complexity. We offer expedited shipping for standard models. All equipment is shipped from our Qingdao port (China) with proper export packaging. -
