Features: 1. In terms of structure: This series of heat exchangers adopts the structural form of square tube sheet and support, which ensures the structural strength and at the same time the appearance is simple and elegant. The whole machine looks the same simple and elegant. 2. Safety performance manufacturing: This series of heat exchangers have been systematically optimized in terms of structural strength, heat transfer, fluid and other aspects in strict accordance with national standards, so that the product can ensure performance, while saving material waste as much as possible, and actively respond to countries that save energy and reduce consumption. It is called for, with the help of computer-aided design and the accumulation of experience in refrigeration container manufacturing for half a century, through advanced processing and welding equipment, the product manufacturing can basically fully meet the design concept. The outstanding advantages are high COP value and low system operating costs; the disadvantage is that the refrigerant charge is large and easy to leak. Operating conditions: This series of products have been widely used in air conditioning conditions, water source heat pumps, ground source heat pumps and other conditions. Due to the requirement of water quality for shell and tube heat exchangers, it is more flexible than plate type. Application: This series of heat exchangers has been widely used in aerospace, military, chemical, textile, shipbuilding, hotels, entertainment and other fields.
