Key Features & Technical Specifications
- Three-effect evaporation design – Maximizes energy efficiency by recycling vapor from each effect, reducing steam consumption by up to 60% compared to single-effect systems.
- 304 Stainless Steel construction – Offers excellent corrosion resistance and durability, suitable for acidic and alkaline solutions.
- Vacuum system integration – Lowers boiling point, allowing gentle evaporation of heat-sensitive materials and preventing product degradation.
- Touch Screen PLC Control – User-friendly interface for real-time monitoring of temperature, pressure, flow rate, and automatic adjustments; supports data logging and remote access options.
- Compact footprint – Space-saving layout compared to traditional evaporators, with optional skid-mounted design for easy installation.
- Customizable capacity – Available from pilot scale (50 L/h) to industrial scale (up to 20,000 L/h) – contact us for specific requirements.
- Low maintenance – CIP (Clean-in-Place) capability and easy access to heat exchangers and separators.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a three-effect and single-effect evaporator?
A: A three-effect system uses vapor from the previous effect to heat the next effect, conserving steam. It is about 3 times more energy-efficient than a single-effect system, making it ideal for large-scale continuous operation. -
Q: Can this system handle highly viscous or scaling liquids?
A: Yes. The design includes forced circulation or falling film options to handle viscous fluids. For scaling-prone solutions, we recommend a special scraper or self-cleaning heat exchanger – optional upgrades available. -
Q: Is the touch screen control compatible with remote monitoring?
A: Yes. The PLC system supports Modbus RTU/TCP protocols, allowing integration with SCADA or remote monitoring systems. We can also provide a web-based dashboard upon request. -
Q: What materials are available besides 304 SS?
A: We offer 316L stainless steel, duplex stainless steel, and titanium for highly corrosive environments. Please specify your solution composition for material recommendation. -
Q: What is the typical delivery time?
A: Standard models are 30–45 days after order confirmation. Customized systems may require 60–90 days, depending on complexity. We prioritize urgent requests from existing clients. -
Q: Do you provide installation and training?
A: Yes. We offer on-site installation supervision and training for your operators. Remote video guidance is also available for minor adjustments. -
Q: What certifications do your products meet?
A: Our manufacturing facility is certified with ISO9001, ISO14001, OHSAS18001, and many other standards. Specific product certifications (e.g., CE, ASME) can be provided as per your requirements at additional cost. -
Q: Can I test the system with my solution before purchase?
A: Absolutely. We have a pilot-scale three-effect evaporation crystallizer in our lab. You can send your sample for a free feasibility test; we will provide a detailed report and recommended design.
