Frequently Asked Questions
-
Q: What is the maximum feed water salinity for this evaporator?
A: The system can handle feed water with TDS up to 45,000 mg/L, which covers typical seawater levels. For higher salinity, we recommend optional pretreatment or a different configuration. -
Q: Can the system be customized for different capacities?
A: Yes, we offer customization for capacity ranging from 1 to 100 m³/h. Please provide your specific requirements for a tailored solution. -
Q: What kind of energy source does it require?
A: The evaporator typically uses low-pressure steam (0.2–0.4 MPa) or hot water as a heat source. Electric heating can be provided as an option. -
Q: How much maintenance is needed?
A: Routine maintenance includes periodic cleaning of heat transfer surfaces and inspection of pumps and valves. The automatic control system will alert you to any abnormal conditions. Under normal operation, maintenance intervals are 3–6 months. -
Q: Is the system easy to install?
A: The unit is pre-assembled and tested in our factory. On-site installation requires connection to utilities (power, steam, feed water, and product water lines). We provide installation guidance and optional commissioning service. -
Q: What certifications does the product have?
A: Our evaporator is manufactured in accordance with ISO9001 quality management system. Specific product certifications such as CE or ASME can be arranged upon request depending on destination requirements. -
Q: What is the warranty period?
A: We offer a standard warranty of 12 months from the date of commissioning or 18 months from delivery, whichever comes first. Extended warranty options are available. -
Q: Can the system operate in cold climates?
A: Yes, the evaporator can be insulated and equipped with freeze protection measures. We can adapt the design to ambient temperature conditions as needed.
