Qingdao Conqinphi Environmental Technology Group Co., Ltd., a trusted manufacturer since 2015 with a factory spanning 10,000–30,000 m² and annual export value exceeding US$10 million, proudly introduces the Stainless Steel 2205/316L/304/316 MVR Evaporation Concentration Crystallizer. This advanced system is engineered for reliable operation in demanding industrial environments, offering exceptional corrosion resistance and energy efficiency. By leveraging mechanical vapor recompression technology, our crystallizer significantly reduces energy consumption while achieving high-purity crystallization and concentration. Whether you're treating wastewater, concentrating chemical solutions, or recovering valuable solids, this equipment delivers consistent performance with minimal maintenance.
Key Features & Technical Specifications
- Premium Material Options: Choose from SS304, SS316, SS316L, or SS2205 to match your specific corrosive environment. Duplex SS2205 offers superior strength and chloride stress corrosion cracking resistance.
- Energy-Saving MVR Technology: Reuses vapor latent heat, reducing steam consumption by up to 70% compared to traditional evaporators.
- Reliable Operation: Low fouling design, anti-scaling coating available, and automatic CIP (clean-in-place) system for extended uptime.
- Customizable Capacity: From laboratory-scale (1 m³/day) to large industrial units (100+ m³/day).
- PLC & HMI Control: Fully automated with remote monitoring capability, ensuring stable process parameters.
- Compact Footprint: Vertical or horizontal layout to fit existing plant space.
- Comprehensive Safety: Overpressure protection, temperature sensors, and emergency shutdown included.

Our MVR crystallizer is specifically designed to handle high-salinity wastewater, chemical mother liquors, and pharmaceutical intermediates. The forced circulation design prevents scaling and fouling, even when processing solutions with high suspended solids. Each unit undergoes rigorous quality control during manufacturing, including hydrostatic testing and surface passivation. Benefits your business gains: lower operating costs (reduced steam and cooling water), minimal waste discharge (zero liquid discharge possible), and high purity crystalline products suitable for reuse or sale.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between SS2205 and SS316L for this crystallizer?
A: SS2205 (duplex) offers higher mechanical strength and better resistance to chloride stress corrosion cracking, making it ideal for seawater or high-chloride brines. SS316L is more cost-effective for less aggressive environments. -
Q: Can this equipment handle highly viscous liquids?
A: Yes, our forced circulation design can handle viscosities up to 5000 cP. For extremely viscous media, optional scraped-surface or heating jacket modifications are available. -
Q: What is the typical payback period for energy savings?
A: Depending on your local energy costs and operating hours, many clients see a payback within 12–24 months due to reduced steam and electricity consumption. -
Q: Do you provide after-sales support and spare parts?
A: Absolutely. We offer a standard 12-month warranty and lifelong technical support. Spare parts (seals, gaskets, compressor parts) can be shipped from Qingdao port within a short lead time. -
Q: Can the crystallizer be used for zero liquid discharge (ZLD)?
A: Yes, combined with a pre-treatment system, our MVR crystallizer is widely used in ZLD applications to recover clean water and dry solids. -
Q: Is the control system customizable for remote monitoring?
A: Yes, we can integrate SCADA or IoT modules for remote data logging and control. Please specify your requirements during inquiry. -
Q: What certifications does your factory hold?
A: Our factory is certified with ISO9001, ISO14001, OHSAS18001, SA8000, and others. We also comply with international standards for pressure vessels (ASME or equivalent upon request).
