Frequently Asked Questions
-
Q: What is the maximum operating temperature of this evaporator?
A: The recommended crystallization temperature range is 60-80°C, but it can be adjusted based on the specific solution properties. Our control system allows precise temperature setting. -
Q: Can this evaporator handle other chemicals besides sodium sulfite?
A: Yes, with appropriate material selection (e.g., SS316L for higher corrosion resistance), it can process other sulfite, sulfate, or chloride solutions. Please consult our engineers for compatibility. -
Q: What is the typical crystal size obtained?
A: Crystal size can be controlled by adjusting residence time, temperature, and circulation rate. Typically, we achieve 0.5-2 mm crystals, but finer or coarser sizes are possible with process optimization. -
Q: How long does the equipment last before major maintenance?
A: With proper operation and regular cleaning, the evaporator can last 10-15 years. Stainless steel construction resists corrosion, and key components like pumps and seals are easily replaceable. -
Q: Is the system fully automated?
A: Yes, it comes with a PLC and HMI touch screen that monitors temperature, pressure, flow rate, and liquid levels. Automatic start/stop, alarms, and data logging are included. -
Q: Do you provide installation and commissioning support?
A: Absolutely. We offer remote guidance and on-site commissioning services (subject to conditions). Detailed manuals and video tutorials are also provided. -
Q: What is the lead time for this model?
A: Standard lead time is 30-45 days after order confirmation, depending on customization requirements. We can expedite for urgent orders. -
Q: Can I get a sample test before purchasing?
A: Yes, we have a pilot-scale test facility. You can send your sodium sulfite solution for a trial run, and we will provide a detailed report on performance and crystal quality.
