Product Introduction
As the scale of newly built petrochemical enterprises increases, the requirements for external heat exchangers in large catalytic units become greater, especially for large units where the weight of the heat extraction tube bundle can reach hundreds of tons. For the construction period of the unit, on-site lifting may not be a problem and large cranes (often 800-1000 tons) are still needed. However, in the subsequent maintenance process of the unit, due to limited space, it is often difficult to replace and lift the tube bundle. For large-scale facilities, Qingdao Jingrun has developed a detachable dedicated external heat exchanger.

Technical features:
 

1. Adopting a multi flange (or double flange) hierarchical structure and modular processing;
2. Optimize the arrangement of heat extraction tube bundles, increase the flow rate of catalyst channels, and achieve better fluidization;
3. Reduce the lifting weight of large items and save maintenance costs;
4. Easy and convenient installation, reducing on-site maintenance time.
