JAD Series Tube bundle heat exchanger shell and all-stainless steel welding production, no gasket, the working pressure 1.6MPa, highest working temperature of up to 400 ℃.
2, plate heat exchanger used in high temperature and pressure of the steam - water heat conditions, the sealing gasket and easy to aging, the frequent need to remove, replace gaskets, high maintenance costs. JAD series of heat exchangers during operation itself without maintenance, cleaning is simple and low cost.
3, JAD heat exchanger at a high temperature, high pressure steam conditions, is even more evident advantages, the general board for the restrictions; for water - water heat exchanger such as symmetry conditions, the board for a more competitive advantage.
4, plate heat exchanger plate spacing is only 2-3mm, easy plug and the internal heat exchanger diversion trough structure complex, slow water flow rate of fouling tendency; and because the plate heat exchanger gasket sealing reasons, the heat exchanger fouling or clogging after chemical cleaning can not only clean the board removed the piece; in damage not only easy to disassemble and clean the sealing plate, resulting in increased cleaning costs, but also because of manual cleaning, resulting in heat exchanger plate The damage to the film surface, resulting in pitting corrosion, affecting the life of the heat exchanger.
JAD heat exchanger 100 ° connection and screw thread structure, a unique surface treatment technology and media on both sides of the countercurrent heat exchanger to achieve a high flow rate, temperature gradient is small, dirt coefficient characteristics, low fouling tendency.
Even after scaling phenomenon long-term use can also be used quickly descaling chemical cleaning methods, saving time, effort, low cost, good effect.
5, JAD series of heat exchangers integrated high heat transfer coefficient, heat transfer effect.

JAD series heat exchanger and the volume of domestic hot water heat exchanger applications in comparison
JAD series of heat exchangers for the European Union EU imported products, is SECESPOL International Group with Poland Gdansk University of Technology Institute of the heat transfer technology and a number of the essence, invented in 1988, the production of a spiral-ribbed tube heat exchanger.
