Tubular Skid-Mounted MVR Evaporator 304 Stainless Steel With PLC Control 220V 50Hz
Product Spotlights
Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been a dedicated manufacturer of advanced evaporation solutions since 2015, exporting to over 20 countries worldwide. Our Tubular Skid-Mounted MVR Evaporator in 304 Stainless Steel with PLC Control (220V 50Hz) represents the pinnacle of energy-efficient liquid concentration technology. Designed for industrial clients who demand reliability and low operating costs, this system integrates mechanical vapor recompression (MVR) to dramatically reduce steam consumption compared to traditional multi-effect evaporators. The fully automated PLC control ensures stable operation with minimal manual intervention, while the skid-mounted package simplifies installation and commissioning. Whether you are treating high-salinity wastewater or concentrating valuable process streams, this evaporator delivers consistent performance with a compact footprint.
Key Features and Technical Advantages
- Energy Efficiency: MVR technology recycles vapor heat, achieving energy savings of up to 80% compared to conventional evaporators. The system only requires a small amount of electricity to drive the compressor, eliminating the need for large steam boilers.
- Corrosion-Resistant Construction: All wetted parts are made from premium 304 stainless steel (optional 316L or duplex available). This ensures long service life even when processing acidic or chloride-containing liquids.
- PLC Control with Touchscreen: The Siemens-brand PLC (or equivalent) provides real-time monitoring of temperature, pressure, flow rate, and compressor speed. Operators can easily adjust parameters via a 7-inch HMI interface, and alarms trigger automatic shutdown for safety.
- Skid-Mounted Design: Pre-assembled on a heavy-duty carbon steel skid frame, the unit integrates evaporator, compressor, condenser, pumps, and piping. This reduces on-site installation time by up to 70% and allows easy relocation if production needs change.
- Low Maintenance: Tubular heat exchanger design resists fouling and is easy to clean. The semi-hermetic compressor features automatic oil return, extending service intervals beyond 8,000 hours.

Benefits for Your Business
- Reduced Operating Costs: With MVR technology, your electricity cost is only about 1/3 of the steam cost for traditional evaporation. Our reference clients report ROI within 12–18 months.
- Environmental Compliance: Achieve zero liquid discharge (ZLD) targets more economically. The evaporator can concentrate brine to over 20% solids, minimizing disposal volume.
- Flexible Integration: The skid-mounted unit comes with pre-wired electrical cabinets and pre-piped connections. Simply connect to your feed, product, and utility lines — no special foundation required.
- Reliable After-Sales Support: Our factory in Qingdao (10,000–30,000 sqm) houses a dedicated service team. We offer remote PLC support, spare parts kits, and on-site commissioning assistance.

Frequently Asked Questions
-
Q: What is the typical payback period for an MVR evaporator compared to a steam-driven system?
A: Based on our customer cases, the payback period is usually between 12 and 24 months, depending on local energy prices and operating hours. The higher your steam cost, the faster the return. -
Q: Can this evaporator handle liquids with high viscosity or scaling tendency?
A: Yes. The tubular design allows for mechanical cleaning (brush or pigging) and the PLC can schedule automatic flushing cycles. For extremely scaling fluids, we recommend optional forced circulation or a scraper blade upgrade. -
Q: What is the required maintenance frequency for the compressor?
A: The semi-hermetic compressor requires oil change every 8,000 operating hours and general inspection every 16,000 hours. We provide a maintenance manual and remote monitoring to help you plan. -
Q: Can the 220V 50Hz supply be changed to other voltages like 380V 60Hz?
A: Absolutely. The standard power supply is 220V 50Hz, but we can customize the motor, transformer, and electrical components for 380V, 415V, 460V, 480V, etc., at 50 or 60 Hz. Please specify when ordering. -
Q: How long does it take for delivery and installation?
A: Lead time is typically 45–60 days after order confirmation, depending on capacity and customization. Installation at your site can be completed within 3–5 days with our technician assistance. -
Q: What is the maximum concentration achievable with this MVR evaporator?
A: It depends on the feed material. For common salt solutions, we can reach up to 25% solids (limited by solubility). For organic liquids, up to 50% or higher. We can run a laboratory test on your sample to confirm. -
Q: Do you provide warranty and spare parts?
A: Yes. Standard warranty is 12 months from commissioning or 18 months from shipment, whichever comes first. We keep a comprehensive stock of spare parts for all major components. -
Q: Is the PLC control compatible with remote monitoring or SCADA systems?
A: Yes. The PLC supports Modbus TCP/IP communication. We can integrate with your existing DCS or provide a cloud-based monitoring option (user name and password for remote access).
