Benefits for Your Chemical Processes
- Energy Efficiency: Multiple effect design reduces steam consumption significantly. For example, a 3-effect evaporator uses only 0.33 kg of steam per kg of water evaporated, compared to 1.1 kg for a single-effect unit.
- Product Quality: Gentle evaporation at low temperatures minimizes thermal degradation of heat-sensitive chemicals, preserving product integrity.
- Operational Simplicity: PLC control automates start-up, shutdown, and parameter adjustments. Operators can monitor the system remotely via SCADA integration.
- Compliance & Safety: Built with safety certifications and robust materials to meet stringent chemical industry standards. All units undergo factory testing before shipment.
- Reduced Downtime: Modular design and easy access to heat exchangers allow quick cleaning and maintenance, maximizing uptime.
- Scalability: Multiple units can be combined for larger capacities, or we can design a single custom unit for your specific needs.
Our evaporator has been successfully installed in over 50 chemical plants worldwide, handling various solutions such as sodium sulfate, ammonium chloride, and organic solvents. The 304 stainless steel construction ensures long service life even in corrosive environments. With PLC control, you can achieve precise temperature and pressure control, resulting in consistent product quality and reduced operational costs.

Frequently Asked Questions (FAQ)
-
Q: What is the typical payback period for this evaporator?
A: The payback period depends on your energy costs and throughput. In many cases, clients see a return on investment within 12–18 months due to significant steam savings. -
Q: Can the evaporator handle viscous or scaling liquids?
A: Yes, we can design the evaporator with special features such as forced circulation or scraped surface heat exchangers for high-viscosity or scaling-prone liquids. Please provide your fluid properties for a custom solution. -
Q: What control system is used? Can it integrate with existing DCS?
A: The standard PLC is Siemens S7-1200 with a 7-inch HMI. We can also use Mitsubishi, Allen-Bradley, or other brands. It supports Modbus, Profibus, or Ethernet/IP for integration with your plant DCS. -
Q: What is the warranty period?
A: We offer a standard 12-month warranty from the date of commissioning. Extended warranty options are available upon request. -
Q: Do you provide installation and commissioning support?
A: Yes, we can send our engineers to your site for installation supervision and commissioning. Alternatively, we provide detailed manuals and remote support via video call. -
Q: Can the evaporator be used for food-grade applications?
A: The 304 stainless steel construction is suitable for many food applications. However, for food-grade compliance, we recommend upgrading to 316L stainless steel and ensuring sanitary design. Our HACCP certification helps meet food safety standards. -
Q: What is the lead time for a standard unit?
A: Typically 30–45 days after receiving the order and down payment. Custom units may take 60–90 days depending on complexity. -
Q: How do I determine the correct number of effects for my application?
A: Our engineering team will evaluate your feed concentration, desired final concentration, steam cost, and available space. Generally, 3 effects offer a good balance of efficiency and cost. We provide a free analysis upon request.
