Central cleaning systems supply high-pressure water for multiple washdown areas or stations within a facility. Because the flow and pressure demand vary based on the job, central cleaning systems may use more than one pump and make use of VFD (Variable Frequency Drive) controls. Central cleaning systems equipped with VFD reduce energy and water consumption, two important operational variables
The versatility of central cleaning systems is based on the design to efficiently and effectively clean a facility and process equipment with the appropriate amount of flow and pressure. Cleaning times can be reduced with the proper pressure applied. However, too low of a pressure can result in the waste of large volumes of water. Excessive pressure can damage process equipment while creating aerosols that may contaminate surfaces.
Centralized cleaning systems generally employ the use of various complementary accessories, such as the following items:
- Shut-off guns
- Chemical (soaps and disinfectants) injection
- Belt cleaners
- High-pressure nozzles
One key factor in pump selection is the peak demand flow. Pumps and motors need to be sized for this maximum. The use of VFD or system valving helps regulate flow and pressure other than peak. With the appropriate sensors in place, the system automatically changes the flow based on demand. With the resultant energy savings, the cost of the VFD is often covered in less than a year.
Using a central cleaning system reduces the cost of multiple systems and maintenance expenses. Fitted with industrial-grade high-pressure water pumps and accessories from Cat Pumps, long service life with less downtime is achieved. With field-proven dependability in applications around the globe, Cat Pumps provides the best high-pressure pumps and systems for centralized cleaning systems.
