Sterile Double Tube Sheet Heat Exchanger Product Introduction:

The unique design of the double-tube-plate heat exchanger facilitates easy draining and maintenance of cleanliness within the tubes. The double-tube-plate structure eliminates the risk of cross-contamination commonly found in conventional heat exchangers, meeting or exceeding the requirements for equipment safety and hygiene. Compact in size yet highly efficient.

Section 3: Design Features of Double-Shell and Tube Heat Exchangers:

1. Material selection and surface finish for double-tube plate heat exchangers
The brazed plate heat exchangers are made of 316L (00Cr17Ni14Mo2) stainless steel, effectively preventing cracking due to different expansion coefficients of the material. The smooth surface is achieved through electro-polishing, which removes exposed impurities and the surface layer, ensuring a roughness of Ra<0.5μm (EP grade), thereby reducing the retention of microorganisms and impurities, and controlling the formation of biofilms.

2. Double header plate structure design
The double tube sheet heat exchanger employs a unique double tube sheet structural design, which minimizes the risk of cross-contamination from the mixing of the tube and shell-side media.

3. Full-length empty design
The double-tube plate heat exchanger is designed with a low drainage point, enabling full drainage of the medium inside the tubes. This effectively prevents the growth of microorganisms.

4. Mini-gap design
Under the premise of ensuring safe operation, the double-shell heat exchanger utilizes an optimized design of small gaps between the heat exchange tubes. This design allows for the maximum increase of heat exchange tubes within a limited unit area, boosting the number of tubes within the area by several times, thereby significantly enhancing the heat exchange capacity per unit volume. The heat exchanger's heat exchange efficiency is enhanced without increasing its volume.

5. Efficient heat exchange capacity
Shell-and-tube heat exchangers ensure minimal wall thickness for tubes while maintaining safe operation. Each heat exchange tube is designed with a wall thickness of only 1mm, effectively enhancing the heat transfer between cold and hot fluids, achieving approximately five times the heat exchange efficiency of traditional shell-and-tube heat exchangers under the same conditions.

6. Double-tube sheet heat exchanger post-maintenance

The shell-and-tube heat exchangers in the double-tube plate series have a low tendency to scale, with a scaling cycle 5-7 times longer than that of conventional heat exchangers. Even after scaling occurs, the cleaning process is very simple. It avoids the disassembly and reassembly of other heat exchangers; a circulating cleaning with dilute nitric acid is sufficient, making it safe, convenient, and cost-effective.
The double-tube plate heat exchangers also clean their own scale during the SIP and CIP processes, effectively minimizing the time and resources required for later equipment maintenance.
