Application of Temperature Control Process in Inorganic Salt Manufacturing Production Line in the Chemical Industry
Project Name: Application of Temperature Control Process in Inorganic Salt Manufacturing Production Line in the Chemical Industry
Geographical location: Shanxi Province/Yuncheng City
Project Time: July 5, 2025
Equipment selection: 110HP (0℃~30℃) water-cooled variable frequency screw chiller
[Simpson Medium Temperature Series] Application of temperature control process in the inorganic salt manufacturing production line of the chemical industry in Xia County, Yuncheng, Shanxi, using Simpson water-cooled variable frequency screw chillers. Because it uses a water cooling system, compared to air-cooled systems, water-cooled units provide greater cooling capacity and higher energy efficiency at the same power. However, water-cooled units require matching cooling towers, making installation more complex than air-cooled units and more affected by winter ambient temperatures. The unit adopts variable frequency technology to automatically adjust cooling output according to the on-site terminal load, achieving high efficiency and energy saving. It uses Siemens PLC controller SMART200 for remote communication control with the user's host computer. Simpson provides an overall process cooling solution design. Our technical staff provide on-site service for unit commissioning and technical training, successfully delivering to the client. The variable frequency series products are suitable for multiple industrial production terminals with varying heat loads, saving at least 30% more energy compared to conventional models.
