Qingdao Conqinphi Environmental Technology Group Co., Ltd. is proud to present our Double Tube Type Evaporator, engineered with premium 316L stainless steel for superior corrosion resistance and durability. This evaporator features a compact 1.5 m² heat transfer area and is designed to operate reliably at 10 bar working pressure, making it an ideal solution for concentration processes in the chemical, pharmaceutical, and food industries. With our advanced manufacturing capabilities and strict quality control, we deliver high-performance evaporation equipment that maximizes efficiency and minimizes downtime.
Our Double Tube Evaporator is constructed using a double-tube design that enhances heat transfer efficiency while reducing fouling and maintenance. The 316L stainless steel material ensures excellent resistance to corrosive fluids and high temperatures, extending the equipment's lifespan. The 1.5 m² heat transfer area is optimized for small to medium-scale production lines, and the 10 bar pressure rating allows for processing under moderate to high pressure conditions, suitable for various evaporation applications.
Key Features & Technical Specifications
- Material: 316L Stainless Steel (AISI 316L) – excellent corrosion resistance, especially in chloride environments.
- Heat Transfer Area: 1.5 m² – compact yet efficient for precise thermal duty.
- Working Pressure: 10 Bar (145 psi) – suitable for many industrial processes.
- Design: Double tube configuration – provides high heat transfer coefficient and easy cleaning.
- Surface Finish: Internal and external surfaces polished to Ra ≤ 0.8 μm, meeting hygiene standards.
- Customizable Options: Flanged or threaded connections, various gasket materials, and mounting brackets.

Advantages & Benefits for Your Process
- Enhanced Heat Transfer Efficiency: The double-tube design creates turbulent flow, significantly improving the overall heat transfer coefficient compared to single-tube designs.
- Reduced Fouling & Easy Cleaning: Smooth polished surfaces and straight tube geometry minimize product buildup, and the design allows for easy mechanical or chemical cleaning (CIP).
- Corrosion Resistance: 316L stainless steel provides excellent resistance to pitting and crevice corrosion in chloride-containing environments, ensuring long service life.
- Compact Footprint: With only 1.5 m² heat transfer area, this evaporator is ideal for installations with limited space, yet still delivers high evaporation capacity.
- Pressure Versatility: Rated for 10 bar, it can handle both atmospheric and pressurized operations, expanding its application range.
- High-Quality Manufacturing: Our factory, certified with ISO9001, HACCP, and other standards, ensures every unit meets rigorous quality requirements.
