Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our Double Four-Effect Evaporator designed specifically for the pharmaceutical industry. Manufactured in our 10,000-30,000 m² facility since 2015, this evaporator embodies our commitment to precision engineering and process safety. Constructed from 304 stainless steel and complying with GMP standards, it delivers exceptional concentration efficiency while maintaining product purity—critical for pharmaceutical intermediates and APIs. With annual export value exceeding US$10 million and a team of 201–300 skilled professionals, we ensure every unit meets rigorous quality benchmarks.
This evaporator utilizes a double four-effect design to maximize energy recovery and minimize steam consumption. The four-effect configuration allows for progressive concentration, reducing thermal degradation of heat-sensitive pharmaceutical compounds. The entire system is built with sanitary welds, smooth surfaces, and easy-clean features that support CIP/SIP protocols, making it ideal for sterile and high-purity environments.
Key Features & Technical Specifications
- Double Four-Effect Design: Four evaporation stages arranged in series, with each stage recovering heat from the previous stage, delivering up to 40% energy savings compared to single-effect evaporators.
- 304 Stainless Steel Construction: All wetted parts are made of 304 SS, providing excellent corrosion resistance and compatibility with a wide range of pharmaceutical solvents and solutions.
- GMP-Compliant Fabrication: Smooth internal surfaces (Ra ≤ 0.6 μm standard, optional
- Advanced Control System: PLC-based automation with touchscreen interface, monitoring temperature, pressure, feed rate, and concentrate density in real time.
- Modular & Compact Footprint: Pre-assembled skid-mounted design reduces installation time and floor space requirements.
- Multiple Safety Features: Overpressure protection, vacuum break valves, and emergency shutdown system.

Frequently Asked Questions
Q1: What is the difference between a double four-effect evaporator and a standard four-effect evaporator?
A: The term "double four-effect" sometimes refers to a configuration where two parallel streams of four-effect evaporation are combined, or it can indicate a system with four effects but designed with double the heating surface area per effect. In our design, it means a robust four-effect system optimized for high-capacity pharmaceutical applications, providing enhanced heat recovery and redundancy.
Q2: Can this evaporator handle viscous or fouling liquids?
A: Yes, we can customize the design with forced circulation or scraped surface options to handle viscous or fouling fluids. The standard falling film configuration works well for low-to-medium viscosity solutions. Please provide your fluid properties for a tailored recommendation.
Q3: What certifications does the evaporator come with?
A: The evaporator is manufactured under ISO9001 quality management system. It is designed to meet GMP standards. We can provide material certificates (MTC), welding procedure qualification records (WPQR), and pressure test reports. Specific third-party certifications (e.g., ASME, PED) are available upon request at additional cost.
Q4: What is the typical lead time?
A: For standard models, lead time is 60–90 days after confirmation of order and technical specifications. Customized units may require 90–120 days, depending on complexity.
Q5: Does the system include a vacuum pump?
A: Yes, the evaporator can be supplied with a vacuum pump (liquid ring or dry screw) to create the required vacuum for low-temperature evaporation. Please specify your desired vacuum level or whether you want us to recommend based on your process.
Q6: How do you ensure the surface finish meets GMP requirements?
A: We use mechanical polishing and electropolishing techniques to achieve surface roughness Ra ≤ 0.6 μm as standard, with optional Ra ≤ 0.4 μm. Each surface is inspected with a profilometer, and records are provided in the documentation package.
Q7: What after-sales support do you offer?
A: We provide 12-month warranty, online technical support, spare parts availability, and optional on-site commissioning assistance. Our global service network ensures timely response.
Q8: Can I visit your factory or request a reference list?
A: Absolutely. We welcome factory inspections and can arrange visits to our Qingdao facility. We can also share references of similar evaporators supplied to pharmaceutical companies, subject to confidentiality agreements.
