Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – a trusted manufacturer of advanced evaporation solutions since 2015. Our Automatic Tubular Three-Effect Evaporator (380V, 50Hz, steam consumption 0.5 kg/kg water) is engineered to deliver high-efficiency concentration and separation for various industrial liquids. With PLC control and robust tubular design, this evaporator offers reliable operation, energy savings, and minimal maintenance. Whether you need to treat wastewater, concentrate solutions, or recover valuable byproducts, our system is built to meet your process demands.
This three-effect evaporator leverages multiple stages to reuse latent heat, significantly reducing steam consumption. The tubular heat exchanger design ensures excellent heat transfer and resistance to fouling. Combined with an automated PLC control interface, operators can easily monitor and adjust parameters for consistent output quality. Below, we detail the key features, technical specifications, and benefits.
Key Features & Advantages
- Three-Effect Design – Maximizes energy efficiency by utilizing vapor from one effect to heat the next, achieving steam consumption as low as 0.5 kg per kg of water evaporated.
- PLC Automation – Integrated programmable logic controller provides precise temperature, pressure, and level control, reducing manual intervention and human error.
- High-Efficiency Tubular Heat Exchanger – Large surface area and even flow distribution minimize scaling and ensure consistent heat transfer.
- Robust Construction – Available in stainless steel (304/316L) or other corrosion-resistant materials to suit different feed compositions.
- Low Operating Cost – Reduced steam consumption and optimized power usage lower overall operational expenses.
- Easy Maintenance – Modular tubular design allows quick access for cleaning and inspection, minimizing downtime.
- Compact Footprint – Space-saving layout designed for easy integration into existing production lines.
- Multi-Purpose Application – Ideal for chemical, pharmaceutical, food & beverage, and environmental industries.

How It Works
The feed liquid enters the first effect where steam heats it to boiling. The generated vapor then flows to the second effect, which operates at a lower pressure, thus boiling at a lower temperature. This vapor condenses, releasing latent heat to evaporate more water in the second effect. The same process repeats in the third effect. The condensate from each effect is collected, and the concentrated product is discharged from the last effect. The PLC continuously monitors temperature, pressure, and liquid levels to maintain stable operation.
Client Benefits
- Energy Savings – Three-effect design cuts steam usage by up to 70% compared to single-effect evaporators.
- Consistent Quality – Automated control ensures uniform concentration and minimal product degradation.
- Scalability – Modular construction allows future capacity expansion with minimal modifications.
- Operator Safety – Integrated alarms and emergency shutdown protect both personnel and equipment.

Frequently Asked Questions (FAQ)
Q1: What types of liquids can be processed with this evaporator?
This system is suitable for aqueous solutions with low to moderate fouling tendencies, such as wastewaters, chemical intermediates, food concentrates (e.g., milk, juice), and pharmaceutical liquors. For highly corrosive or viscous fluids, please consult our engineers for material and design customization.
Q2: How do I determine the required evaporation capacity?
Please provide the feed flow rate (in L/hr or m³/hr) and the desired concentration ratio. Our technical team will calculate the appropriate model and number of effects to meet your target.
Q3: Can the PLC control interface be integrated with existing DCS or SCADA systems?
Yes, our PLC supports Modbus, Profibus, and Ethernet/IP protocols for seamless integration. Custom communication requirements can be accommodated upon request.
Q4: What is the typical operating pressure range?
The first effect operates near atmospheric pressure (0–0.5 bar g), while the second and third effects operate under vacuum (typically -0.5 to -0.8 bar g) to lower boiling temperatures and maximize efficiency. Exact values depend on the product and desired concentration.
Q5: How often is cleaning required?
Cleaning frequency depends on the feed composition. For clean solutions, intervals can be several weeks. For scaling-prone liquids, a CIP (Clean-in-Place) system can be added. Our standard design includes easy access for manual cleaning.
Q6: What certifications does the product meet?
Our factory is certified under ISO9001, HACCP, and other management systems. The evaporator itself is designed and manufactured according to relevant international standards (e.g., ASME, PED, GB). Specific certification for your country can be arranged upon request.
Q7: What is the warranty period?
We offer a standard 12-month warranty from the date of commissioning. Extended warranty options are available for an additional cost.
Q8: Can I visit your factory to see a demonstration?
Absolutely. Our facility in Qingdao, Shandong, China welcomes customers for on-site visits and trial runs. Please contact our sales team to schedule an appointment.
