Our Automatic MVR Evaporator Crystallizer is built by Qingdao Conqinphi Environmental Technology Group Co., Ltd., a professional manufacturer established in 2015 with a factory size of 10,000-30,000 square meters and annual export revenue of US$10-50 million. This equipment is designed to efficiently evaporate and crystallize industrial wastewater, brine, and process liquids, recovering valuable solids and clean water. With a capacity range of 1 to 10 tons per day, it is ideal for small to medium-scale operations in chemical, pharmaceutical, food, and environmental sectors. The crystallizer features 316L stainless steel construction for superior corrosion resistance and durability, and operates on either 220V or 380V power supply.
The MVR (Mechanical Vapor Recompression) technology dramatically reduces energy consumption by compressing and reusing vapor, achieving up to 60-80% energy savings compared to traditional evaporators. The automatic control system ensures stable operation, minimal manual intervention, and consistent output. Below are the key technical parameters and specifications:
| Parameter | Value / Range |
| Capacity | 1-10 Ton/day (evaporation rate) |
| Operating voltage | 220V/380V, 50/60Hz (customizable) |
| Material of construction | 316L stainless steel (wetted parts) |
| Vapor compressor type | Centrifugal or roots blower (optional) |
| Evaporation temperature | 60-95°C (adjustable) |
| Crystallization method | Forced circulation + external heater |
| Control system | PLC + HMI touch screen (automatic) |
| Footprint | Compact, modular design (customizable) |
Key Features & Benefits
- Energy efficient: MVR technology recycles latent heat, consuming only about 20-40 kWh per ton of water evaporated – significantly lower than multi-effect evaporators.
- High corrosion resistance: All wetted parts are made of 316L stainless steel, ideal for acidic, alkaline, or saline solutions.
- Fully automatic operation: PLC-based control with touch screen allows real-time monitoring, data logging, and remote control options (optional).
- Flexible capacity: The 1-10 ton/day range makes it suitable for pilot plants, industrial scale-up, and decentralized treatment.
- Compact footprint: Skid-mounted design reduces installation space and simplifies on-site setup.
- Low maintenance: Simple mechanical design with corrosion-resistant materials minimizes downtime and replacement parts.
- Customizable configuration: Options include different compressor types, heating methods, and auxiliary equipment (pre-concentrator, dewatering unit).
- Wide application: Used for brine concentration, zero liquid discharge (ZLD), salt recovery, and wastewater volume reduction.
The crystallizer operates on the principle of forced circulation: the feed liquid is heated by a heat exchanger, then enters a separation chamber where vapor is released and compressed by the MVR compressor. The compressed vapor is returned to the heat exchanger to continue the heating cycle. The concentrated slurry then flows into the crystallizer section where solids precipitate and can be discharged as reusable salt or waste. This closed-loop system maximizes recovery and minimizes waste.

Frequently Asked Questions (FAQ)
-
Q: What is the typical energy consumption of this MVR crystallizer?
A: For most applications, the specific power consumption ranges from 20 to 40 kWh per ton of evaporated water, depending on the evaporation temperature and salt concentration. This is significantly lower than traditional thermal evaporators. -
Q: Can the equipment handle highly corrosive liquids like hydrochloric acid or sodium hydroxide?
A: Yes, the wetted parts are made of 316L stainless steel, which offers good resistance to many acidic and alkaline solutions. For extremely corrosive media, we can upgrade to duplex stainless steel or titanium upon request. -
Q: What is the maximum solid content in the feed that the crystallizer can process?
A: The forced circulation design can handle feed with suspended solids up to about 5% by weight. For higher solids, we recommend pre-filtration or a two-stage system. Please provide your feed analysis for a tailored solution. -
Q: Is the system fully automatic? Do I need an operator on site?
A: The control system is PLC-based with HMI, allowing automatic start-up, operation, and shutdown. Under normal conditions, one operator can monitor multiple units. Remote control and alarm functions are available. -
Q: What is the delivery lead time and shipping port?
A: Standard delivery time is 30-45 days after order confirmation, depending on configuration. All equipment is shipped from Qingdao Port, China. We can arrange FOB, CIF, or DDP terms. -
Q: What certifications does the product have?
A: Our company is ISO9001, ISO14000, OHSAS18001 certified. The equipment itself can be manufactured to meet specific standards (PED, ASME, etc.) as optional, upon request. -
Q: Can the capacity be customized outside the 1-10 ton/day range?
A: Yes, we design custom systems for capacities from 0.5 ton/day to 100 ton/day. The 1-10 ton/day range is our standard modular series for quick delivery. -
Q: What is the warranty period and after-sales support?
A: We offer a 12-month warranty covering manufacturing defects. After-sales support includes remote troubleshooting, spare parts supply, and optional on-site training. Our service team is available 24/7.
With over 9 years of manufacturing experience, Qingdao Conqinphi has supplied more than 500 evaporation systems worldwide. Our dedicated engineers and quality assurance team ensure reliable operation and customer satisfaction.
