https://korean-machinery.com///inquiry

[INQ. NO. 2607M04] Kyung In Machinery Co., Ltd. has been focusing on research and development based on its cooling tower research institution having acquired more than 40 patents. Its unique technologies are widely recognized in the industry, and a number of entities are visiting from all over the world to find out more about Kyung In’s know-how and technology.
Kyung In Machinery’s EX/MEX series of the cooling tower utilizes its own crossflow system. This is a newly innovated system that can handle a large capacity in a compact form.

The standard crossflow cooling tower system has the following disadvantage: the dead area where the cooling water passing through the fill material is deflected to one side. It is due to the speed of the air being sucked and not being cooled. However, the highly efficient fill material of the EX/MEX series of the cooling tower system is patented through its extraordinary technology, and shows no disadvantages.
The usage of a PVC cellular type drift eliminator and wide mounting space reduces drift to less than 0.002%. Furthermore, it is the least drift type among the cooling tower systems through showing a very low probability of legionella propagation.
To maximize heat-exchange efficiency, separate distribution equipment is installed on top of the fill material. The Cooling Tower Institute (CTI) has proven to be a compact, lightweight, high-performance cooling tower. And it has a maximum capacity of 1200 CRT per cell.
The double crossflow system of the cooling tower allows maintenance and repair during the operation. The access door is designed for easy access, and is designed efficiently for inspection and cleaning. What’s more, immediate repair is possible when defects occur on the driving side.
Ultraviolet protection coating (UV coating) is applied to the fill material to minimize the hardening phenomenon, so it does not interfere with the related systems (main equipment, pump, piping) due to breakage.

Kyung In Machinery is the market-leading cooling tower manufacturer in Korea. With numerous projects and an ongoing commitment to research and development programs, the company has been accumulating top-class expertise in cooling towers.
“We have been doing our utmost to develop new environmentally friendly cooling towers through our long-term technical partnership with Marley USA and training courses with foreign experts,” a spokesperson for the company commented.
