Qingdao Conqinphi Environmental Technology Group Co., Ltd. — a leading manufacturer with over 10 years of experience and a 10,000–30,000 m² factory — is proud to present our Triple-effect vacuum evaporator with a capacity of 500 L/h, built from 304 stainless steel and equipped with PLC control for continuous operation. This system is designed to efficiently reduce liquid waste volume, recover valuable distillate, and significantly lower energy consumption through triple-effect heat recovery. Whether you are treating industrial wastewater, concentrating chemical solutions, or recycling process water, this evaporator offers reliable, automated, and cost-effective performance.
Our evaporator integrates advanced thermal engineering with robust construction, ensuring long service life and minimal maintenance. The PLC touchscreen interface allows operators to monitor and adjust parameters in real time, while the 304 stainless steel resists corrosion even in harsh environments. With annual exports exceeding US$10 million and a global presence across North America, Europe, Asia, and more, Conqinphi has become a trusted partner for environmental solutions.
Key Features & Technical Specifications
- Triple-effect design — uses vapor from one effect to heat the next, reducing steam consumption by up to 60% compared to single-effect units.
- 500 L/h evaporation rate — suitable for medium-scale continuous wastewater treatment or concentration processes.
- 304 stainless steel construction — excellent corrosion resistance; optional upgrade to 316L for aggressive chemicals.
- PLC + HMI control — fully automatic operation with touchscreen interface; remote monitoring capability available.
- Vacuum system — low-temperature boiling reduces scaling and allows treatment of heat-sensitive liquids.
- Compact footprint — modular design for easy installation and integration into existing lines.
- Low maintenance — self-cleaning option (CIP) and easy access to heat exchanger surfaces.
- Continuous operation — automatic feed, concentrate discharge, and distillate collection for 24/7 processing.

Detailed Advantages & Customer Benefits
Energy Efficiency: The triple-effect design maximizes heat reuse, cutting operational costs significantly. For a typical 500 L/h application, energy savings can exceed 50% compared to single-effect systems, translating into a shorter payback period.
Automation & Reliability: Our PLC control system manages feed rate, temperature, vacuum, and concentrate density automatically. Operators can set parameters via the touchscreen and monitor performance remotely. This reduces human error and ensures consistent output even during overnight shifts.
Material Quality: 304 stainless steel is standard for excellent corrosion resistance in most industrial wastewater scenarios. For applications involving chlorides or low pH, an optional 316L upgrade is available. Every weld is inspected to meet international standards.
Continuous Operation: The evaporator is designed for 24/7 continuous duty. Its self-cleaning cycle (optional CIP) minimizes downtime for manual cleaning. The concentrate discharge system automatically removes concentrated residue, maintaining stable performance.
Environmental Compliance: By reducing liquid waste volume by up to 95%, this evaporator helps facilities meet discharge regulations and reduce disposal costs. The recovered distillate can often be reused in process or as boiler feed water.

Frequently Asked Questions
-
What types of wastewater can be treated with this triple-effect evaporator?
This evaporator is suitable for a wide range of industrial wastewaters, including those from metalworking (cutting fluids, coolants), chemical processing, pharmaceuticals, food & beverage, printing & dyeing, and landfill leachate. It works best with non-volatile contaminants; for volatile organic compounds (VOCs), additional pretreatment may be required. Please provide your water analysis for a tailored recommendation. -
What is the typical payback period?
Payback depends on local energy costs, disposal savings, and distillate reuse value. Typically, customers see a payback within 1–3 years due to energy savings (triple-effect) and reduced waste disposal fees. We can provide a customized ROI analysis upon request. -
Can the PLC system be integrated with existing SCADA or DCS?
Yes. Our PLC supports common communication protocols such as Modbus RTU/TCP, Profibus, and Ethernet/IP. Integration with your existing control system is possible with additional hardware; we can discuss your specific requirements. -
What is the required installation space?
The unit dimensions are approximately 4.5m (L) × 2.0m (W) × 3.5m (H). Additional clearance for maintenance access, piping, and electrical panel should be considered. Our engineering team can provide a layout drawing based on your site conditions. -
Do you provide installation and commissioning services?
Yes. We offer on-site supervision for installation and commissioning at an additional cost. Our technical support team can also guide your local engineers via remote assistance. Spare parts and training are available. -
What is the warranty period?
Standard warranty is 12 months from the date of commissioning or 18 months from shipment, whichever comes first. Extended warranty options are negotiable. We stand behind our equipment with genuine parts and responsive after-sales service. -
Can the evaporator handle liquids with high solids or scaling tendencies?
Yes. The triple-effect vacuum design operates at lower temperatures, which reduces scaling. Additionally, we can include a forced circulation system or a scraped surface heat exchanger for highly scaling or viscous fluids. An optional anti-scaling agent dosing system is also available. -
How does the energy consumption compare with single-effect evaporators?
A single-effect evaporator typically consumes about 1.1–1.3 kg of steam per kg of water evaporated. Our triple-effect system reduces steam consumption to approximately 0.4–0.6 kg steam per kg of evaporated water, delivering up to 60% energy savings.
