As a leading manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. specializes in advanced evaporation and crystallization solutions. Our Industrial MVR Evaporation Concentration Crystallizer is designed to efficiently concentrate and crystallize fine chemical process streams and pickling wastewater. With over 200 employees and a factory spanning 10,000–30,000 square meters, we deliver robust, energy-saving equipment that reduces operational costs while meeting strict environmental discharge standards.
This system leverages mechanical vapor recompression (MVR) technology to recycle latent heat, achieving up to 70% energy savings compared to traditional multi-effect evaporators. It is ideal for treating high-salinity, acidic, or corrosive waste streams, helping clients recover valuable by-products and achieve zero liquid discharge (ZLD).
The crystallizer is fully customizable, with options for different compressor types, materials, and automation levels. Our units have been exported to North America, Europe, Southeast Asia, and other major markets, earning trust through reliable performance and after-sales support.
Key Features & Technical Advantages
- High Energy Efficiency – MVR compressor reuses vapor heat, reducing steam consumption by 90%
- Corrosion Resistance – 316L or duplex stainless steel construction for acidic/chloride-rich environments
- Compact Footprint – Modular design saves floor space compared to conventional evaporators
- Low Operating Cost – Only electrical power required; no external steam boiler needed
- Automatic Control – PLC/HMI with remote monitoring, alarm, and data logging functions
- Flexible Configuration – Forced circulation or falling film type adapted to fouling/scaling tendencies
- Environmental Compliance – Achieves ZLD and recovers clean water for reuse

Frequently Asked Questions
-
Q: What is the typical energy saving compared to conventional evaporators?
A: MVR technology can reduce energy consumption by 60–75% because it recycles latent heat. For every 1 kWh of electrical input, up to 20–30 kWh of thermal energy is recovered. -
Q: Can the system handle highly corrosive pickling wastewater containing HCl or H₂SO₄?
A: Yes, we offer wetted parts in 316L stainless steel, duplex stainless steel, or titanium depending on chloride concentration and pH. Our material selection ensures long service life under acidic conditions. -
Q: What is the minimum and maximum capacity you provide?
A: Our standard range is 1 ton/day to 100 tons/day. Larger capacities can be designed as multiple units or customized skids. -
Q: Do you offer pilot testing before purchasing?
A: Absolutely. We have a mobile pilot MVR unit that can be shipped to your site for field trials, or you can send a sample to our lab in Qingdao for feasibility testing. -
Q: How long does installation and commissioning take?
A: Typically 2–4 weeks on-site, depending on system complexity. We provide a dedicated engineer to oversee startup and train your operators. -
Q: What certifications does your equipment meet?
A: Our manufacturing processes are certified under ISO9001, ISO14000, OHSAS18001, and other management systems. Electrical components comply with CE or UL standards upon request. -
Q: Is the crystallizer suitable for scaling-prone solutions?
A: Yes, we design forced circulation evaporators with high flow velocity and optional anti-scalant injection to minimize fouling. A CIP (clean-in-place) system is also available. -
Q: What is the warranty period?
A: We offer a standard 12-month warranty from commissioning, with extended warranty options available. Spare parts are stocked in our warehouse for quick delivery.
For more detailed technical data sheets, reference list, or a quotation, please send your process parameters (composition, flow rate, temperature, pH) to our sales team. We will respond within 24 hours.
