With an IP65-rated electrical cabinet and PID regulation, this system offers precise, reliable performance in harsh environments, helping you achieve compliance and operational cost savings.
Key Features & Benefits
- PLC + HMI Intelligent Control: Automatic start/stop, fault diagnosis, real-time data logging, and remote monitoring via SCADA (optional). Reduces manual intervention and human error.
- PID Regulation for Optimal Efficiency: Precise control of temperature, pressure, and feed rate ensures stable evaporation, lower energy consumption, and minimal scaling.
- IP65 Electrical Cabinet: Dust-tight and protected against low-pressure water jets—ideal for outdoor or humid industrial environments. Extends component lifespan and safety.
- High-Salt Tolerance: Engineered to handle brine with TDS up to 250,000 mg/L. Anti-crystallization design with automatic blowdown and flushing cycles.
- Modular & Skid-Mounted: Pre-assembled, tested, and ready for quick installation. Available in containerized version for easy transport and relocation.
- Energy Recovery Options: Can integrate mechanical vapor recompression (MVR) or heat pump to reduce energy cost by 30–60% (optional).

Technical Advantages
The integration of PID (Proportional-Integral-Derivative) regulation ensures that process variables stay within tight tolerances, minimizing fluctuations that lead to foaming or scaling. Combined with the IP65-rated cabinet, the electronics are shielded from corrosive vapors and wash-down procedures—common in chemical and food processing plants.
Our evaporator uses a falling-film or forced-circulation design (depending on feed characteristics) to maximize heat transfer while reducing fouling. The PLC controls automatic blowdown cycles based on conductivity readings, preventing salt saturation and maintaining consistent performance.

Frequently Asked Questions
-
What is the maximum salt concentration this evaporator can handle?
It can treat wastewater with TDS up to 250,000 mg/L. For higher concentrations, we offer custom crystallizer options. -
How does the PID regulation improve energy efficiency?
PID maintains optimal temperature and pressure, preventing energy waste from overshooting. It also reduces scaling, so less frequent cleaning is needed. -
Is the IP65 cabinet suitable for outdoor installation?
Yes, it protects against dust and rain. However, direct sunlight exposure may require a sunshade for prolonged life. -
What maintenance is required?
Routine checks include cleaning heat exchanger surfaces, inspecting seals, and verifying sensor calibration. The PLC automatically logs run hours for preventive maintenance. -
Can I integrate this evaporator with my existing plant SCADA?
Yes, our PLC supports Modbus TCP/IP and other common protocols for seamless integration. -
What is the typical lead time?
For standard models, 30–45 days after order confirmation. Custom projects vary based on complexity. -
Do you provide after-sales service and training?
We offer on-site commissioning, operator training, and remote technical support. Spare parts are available globally. -
What certifications does the equipment meet?
Factory is certified under ISO9001, ISO14000, and OHSAS18001. Individual units can be built to CE or ASME standards upon request.
