Customer Background
The customer is a medium-sized industrial manufacturing company located in Selangor, Malaysia. Its plant is equipped with a recirculating cooling water system that provides continuous cooling for production equipment. Previously, the customer used traditional manually cleaned filters, which frequently became clogged. Each cleaning required shutdown and disassembly, not only consuming labor but also affecting the continuity of the cooling water supply. As production capacity increased, the original filtration method could no longer meet the requirements for stable operation.
Requirements and Challenges
The customer faced three core issues. First, suspended particles and impurities in the cooling water accumulated rapidly on the filter screen, causing the pressure differential between the inlet and outlet to rise and the cooling water flow rate to decline. Second, manual cleaning was required too frequently, with each maintenance operation taking approximately 30 to 40 minutes, directly affecting the production schedule. Third, the customer had specific requirements for equipment interface standards, requiring compatibility with the existing JIS-standard piping system on site.
Specified Parameters:
- Flow rate: 5,000 L/h
- Filtration accuracy: 10 microns
- Inlet/Outlet: DN100 JIS flanges
- Drainage: Automatic electric valve
- Material: Corrosion-resistant body
Solution
Based on the customer’s operating conditions, we recommended the JYSCF-200-304 self-cleaning filter. The main body of the unit is a DN200 (219 mm OD) SS304 stainless steel cylinder with a sandblasted surface finish, meeting the corrosion resistance requirements of Malaysia’s hot and humid environment. It is equipped with an SS304 wedge-shaped mesh filter element with a filtration accuracy of 10 microns. The element offers a large flow area and low pressure loss, effectively intercepting fine particles in the cooling water.
The inlet and outlet are fitted with DN100 JIS flanges, allowing direct connection to the customer’s on-site piping without additional adapters. The drain port is equipped with a DN50 electric ball valve, which automatically opens and closes for discharge according to a preset program, requiring no manual intervention.
The cleaning method uses a nylon brush scraping structure. A motor-driven brush rotates to clean the surface of the filter element, without damaging the mesh during the cleaning process. The unit has a design pressure of 1.0 MPa, meeting the customer’s system operating pressure requirements. The compact overall structure controls the footprint while ensuring a treatment capacity of 5,000 L/h.
Delivery and Feedback
Before leaving the factory, the unit underwent complete pressure testing and operational testing, and was accompanied by drawings confirming the JIS flange connection dimensions to ensure compatibility with the customer’s on-site piping. After the equipment arrived at the customer’s plant, installation and commissioning were completed with the assistance of the customer’s engineers.
In the past, we had to assign someone to inspect and clean the filter mesh every shift. Now we only need to check the differential pressure gauge regularly, and the discharge is fully automatic. The cooling water supply has not been interrupted by the filtration process since.
