Shandong Guoxin Industrial Equipment Co., Ltd. of double bellows turbulent heat exchanger has a small, small footprint, easy handling, compact advantages. Dual profile of enhanced heat transfer during the operation, due to the special structure of the inner and outer wall of the fluid state of turbulence and double bellows itself thermal expansion in the flow process, the ability to compensate shrink, so that the heat transfer tube itself has a self-cleaning ability, difficult to scale, suspended solids and impurities in the fluid easily attached to the wall. In order to adapt to different venues and user requirements, the heat exchanger has a vertical, horizontal two forms to adapt to different positions and space. Practice has proved that the device is now in the best heat transfer equipment heat generation product.
