Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. — a dedicated manufacturer with over a decade of expertise in advanced water treatment and evaporation systems. Our PLC Controlled MVR Evaporator for Desalination, constructed from corrosion-resistant 304 stainless steel, is engineered to deliver high-efficiency seawater desalination with a proven capacity of 2 tons per hour (2 T/H). By integrating sophisticated PLC automation, this system simplifies operation, reduces energy consumption, and ensures consistent, high-purity freshwater output. Whether you are addressing municipal water supply, industrial process water needs, or agricultural irrigation, our MVR evaporator stands as a reliable and cost-effective solution.
This equipment leverages Mechanical Vapor Recompression (MVR) technology, which dramatically lowers energy usage by recycling the heat from vapor compression. Compared to traditional thermal desalination methods, our MVR system can achieve energy savings of up to 60-80%. The 304 stainless steel construction guarantees durability and resistance to saline corrosion, making it ideal for long-term operation in coastal or brackish water environments. Backed by our factory’s 10,000-30,000 m² manufacturing facility and a skilled team of 201-300 employees, every unit is precision-engineered and rigorously tested before shipment.

Frequently Asked Questions (FAQ)
- Q1: What is the difference between MVR and traditional thermal evaporators?
- MVR (Mechanical Vapor Recompression) uses a compressor to increase the pressure and temperature of the vapor, which is then used as the heating medium. This recycles the latent heat of vaporization, reducing energy consumption by up to 80% compared to single-effect or multi-effect thermal evaporators that require external steam.
- Q2: Can this evaporator handle seawater with high salinity?
- Yes, our MVR evaporator is designed for feed water with TDS up to 45,000 ppm typical for seawater. For higher salinity (e.g., brine concentration), optional high-pressure compressor and material upgrades (316L SS) are available. Please provide your feed water analysis for a customized recommendation.
- Q3: What is the typical power supply requirement?
- The standard unit is offered with 220V, 3-phase, but we can customize to 380V, 415V, 480V, or other voltages. The total installed power depends on compressor size, typically around 30-40 kW for a 2 T/H system. A detailed electrical specification sheet is provided upon request.
- Q4: How often does the system need maintenance?
- Routine maintenance includes weekly visual inspections of seals and pumps, monthly cleaning of the pre-filter (if installed), and annual replacement of compressor oil and filter elements. The automatic CIP system helps reduce scaling, extending the intervals between major shutdowns. A full maintenance guide is supplied with the equipment.
- Q5: What is the product water quality?
- Under typical seawater conditions (TDS 35,000 ppm), the product water conductivity is below 10 μS/cm (equivalent to TDS
- Q6: Is the system fully automatic? Can it operate unattended?
- Yes, the PLC controls start-up, operation, parameter adjustments, and shutdown sequences. The system can run continuously without manual intervention. Alarms and notifications can be sent via SMS or email if optional cellular modules are purchased. However, we recommend periodic operator checks for optimal safety.
- Q7: What certifications does your company hold?
- Our company holds ISO9001, ISO14000, OHSAS18001, and others. Specific product certifications (e.g., CE, ASME) can be arranged based on your market requirements. Please consult our sales team for details.
- Q8: What is the lead time and shipping port?
- Standard lead time is 30-45 days after order confirmation. Expedited delivery is possible for urgent projects. All units are shipped from Qingdao Port, China. We handle sea, air, or railway freight as per your preference.
