Double tube plate heat exchanger
Double tube plate heat exchanger
Product details
Sanitary double tube plate heat exchanger
Sanitary grade heat exchangers are designed to operate under the highest sanitary grade requirements, and their unique design makes it easy to completely empty and maintain a clean state inside the heat exchange tubes. The double tube plate structure avoids the risk of cross contamination that conventional heat exchangers are prone to.
Product Structure Features:
1. The heat exchange tubes are made of seamless steel pipes.
2. All are made of 316L stainless steel material.
3. Double tube plate design eliminates cross contamination.
4. Product contact side fully emptied design.
5. The heat exchange channel has no dead corners.
6. It can be installed vertically or horizontally.
7. We can customize production according to customer requirements.
working principle:
1. The primary side material flows through the seamless steel pipe bundle processed by electric polishing, while the secondary side medium flows through the outer pipeline in the opposite direction. The end of the heat exchange tube bundle is fastened with a double tube plate and serves as a leakage monitoring point to prevent bidirectional cross contamination between the primary side material and the secondary side medium.
2. Multiple bending expansion joints can be set up to effectively absorb local thermal stress caused by large-scale temperature changes, thereby extending the service life of the heat exchanger.
Technical indicators:
1. Heat exchange area: 0.5-15 square meters
2. Design temperature: up to 165 degrees Celsius
3. Design pressure: up to 1.6MPa
4. Surface treatment: The minimum smoothness of the inner surface of the pipeline in contact with the product is level 8 or above, Ra=0.25—0.5。
5. Welding standards: EN-288-3,EN287-1
6. Installation method: It can be installed horizontally or vertically.
Application fields of sanitary double tube plate heat exchanger:
1. Cooling/heating of injection water;
2. Injection water intake point cooling;
3. Cooling/heating of medicinal solution;
4. Clean steam condensation and cooling, temperature control of high-purity liquids.
5. Pure water heat exchange disinfection.
