As a leading manufacturer from Qingdao Conqinphi Environmental Technology Group Co., Ltd. (established 2015, factory area 10,000-30,000 sqm, 201-300 employees), we present our Multi-effect Evaporation Crystallization Unit – a robust industrial solution designed to maximize energy efficiency and operational simplicity. This unit integrates a PLC control system and a dedicated feed pump, operating at 220V to suit standard electrical infrastructures. It is engineered to handle high-concentration liquid waste, enabling zero liquid discharge (ZLD) and valuable resource recovery across diverse industries. With annual exports exceeding US$10 million and shipments from Qingdao port to over 15 global markets, our equipment combines proven reliability with customizable performance.
Key Features & Technical Specifications
- Multi-effect Evaporation Design: Utilizes vapor from one effect as heating medium for the next, drastically reducing energy consumption (up to 60% less steam compared to single-effect systems).
- PLC Control with HMI: Full automation via programmable logic controller – touchscreen interface for monitoring temperature, pressure, flow, and crystallization progress. Allows remote operation and data logging.
- Integrated Feed Pump: High-pressure, corrosion-resistant feed pump included (220V, 50/60Hz) – ensures stable liquid transfer and consistent operation.
- 220V Operation: Standard single-phase or three-phase (optional) – compatible with most industrial power supplies, reducing installation complexity.
- Crystallization Capability: Designed to produce crystalline solids from concentrated solutions – ideal for salt recovery, pharmaceutical intermediates, and chemical purification.
- Construction Material: Standard 304/316L stainless steel for wetted parts – available with dual-phase steel or titanium upon request for aggressive media.
- Compact Footprint: Skid-mounted design for easy transport and installation, occupying minimal floor space.

Frequently Asked Questions
Q1: What is the typical payback period for this unit?
A1: For most industrial wastewater applications, the combination of energy savings and recovered solids yields a payback period of 12–24 months, depending on local energy costs.
Q2: Can the 220V version be converted to 380V or other voltages?
A2: Yes, the PLC and pump are ordered to match your voltage. 220V is standard, but 380V, 440V, and other options are available upon request.
Q3: What maintenance is required for the PLC system?
A3: Basic inspection of sensors and wiring annually; software updates can be provided by our technical team. The HMI has a long lifespan with minimal upkeep.
Q4: Does the feed pump handle viscous or abrasive liquids?
A4: We select the pump based on fluid properties. For high viscosity or abrasives, we offer progressive cavity or diaphragm pumps. Please provide fluid analysis.
Q5: What is the maximum crystallization capacity we can get?
A5: Standard designs handle up to 10,000 L/h. Custom units can be built for higher capacities – contact us for a feasibility study.
Q6: Are spare parts readily available?
A6: Yes, we stock common parts (seals, gaskets, heating elements, pump impellers) in our Qingdao warehouse, and they can be shipped within 5–10 working days globally.
Q7: Can the unit run 24/7 continuously?
A7: Yes, our units are designed for continuous industrial operation. The PLC includes automatic cleaning cycles and alarm systems to ensure safe 24/7 runtime.
Q8: Do you offer training for operators?
A8: Yes, we provide on-site training during commissioning and detailed manuals. Remote video support is also available.
