As a leading manufacturer from Qingdao Conqinphi Environmental Technology Group Co., Ltd. (established 2015, factory size 10,000–30,000 m²), we proudly present our Energy-Saving Multi-Effect Evaporation Crystallizer designed specifically for chemical and salt production. This advanced system integrates multiple-effect evaporation technology to significantly reduce energy consumption while achieving high-efficiency crystallization. With over 200 skilled employees and an annual export value exceeding US$10 million, we deliver reliable, customized solutions trusted by clients across North America, Europe, and Asia.
Our crystallizer is engineered to handle challenging liquors, high-salinity brines, and chemical by-products. It offers outstanding thermal efficiency, compact footprint, and robust construction. Whether you need to concentrate sodium chloride, recover valuable chemicals, or treat industrial wastewater, this equipment provides a sustainable, cost-effective answer.
Key Features & Benefits
- Multi-Effect Design – Up to 6 effects cascade heat recovery, reducing steam consumption by 70% compared to single-effect units.
- Energy-Saving Operation – Low specific energy consumption (≤0.3 kWh per kg water evaporated) lowers operational costs.
- High Purity Crystals – Controlled evaporation and crystallization produce uniform, high-purity salt or chemical crystals.
- Broad Application Range – Suitable for NaCl, KCl, Na₂SO₄, NH₄Cl, and various organic/inorganic solutions.
- Corrosion-Resistant Materials – Standard in SS316L; titanium or duplex stainless steel available for aggressive media.
- Fully Automatic Control – PLC + HMI system with remote monitoring, alarms, and data logging.
- Compact & Modular – Skid-mounted design minimizes installation space; expandable for higher capacity.
- Low Maintenance – Anti-scaling design, easy access for cleaning, and long service life.

Frequently Asked Questions (FAQ)
1. What is the typical energy saving compared to single-effect evaporators?
Our multi-effect design can reduce steam consumption by 60–70%, depending on the number of effects. With 4–6 effects, the specific energy consumption drops to as low as 0.25 kWh per kg of water evaporated.
2. Can this crystallizer handle high-salinity brine (e.g., 25% NaCl)?
Yes. The system is designed for high-concentration solutions. We use special anti-scaling coatings and optimized circulation to prevent salt precipitation on heat transfer surfaces. For extremely high salinity, we can incorporate a forced circulation design.
3. What materials are available for corrosive chemicals?
Standard material is SS316L. For chlorides, acids, or alkalis, we offer titanium, Hastelloy, or duplex stainless steel. Please provide your feed composition for a material recommendation.
4. What is the minimum order quantity (MOQ)?
We accept orders starting from 1 unit. For custom designs, a feasibility study may be required. Multiple units are often ordered for large-scale production lines.
5. How long does installation and commissioning take?
Typically 2–4 weeks on-site after delivery, depending on site preparation. Our engineers provide supervision and training. Remote support is available after commissioning.
6. Do you provide after-sales service and spare parts?
Yes. We offer a 12-month warranty, lifetime technical support, and a global spare parts network. Common spare parts such as seals, gaskets, and control modules are kept in stock.
7. Can this system be integrated with existing MVR (mechanical vapor recompression) technology?
Absolutely. Our multi-effect evaporator can be combined with an MVR compressor for even higher energy efficiency. This is a popular option for clients aiming for zero liquid discharge (ZLD).
8. What is the typical lead time?
Standard models require 30–45 days after order confirmation. Custom designs may take 60–90 days depending on complexity. We prioritize urgent projects upon request.
