Energy & Power Sector
The energy and power industry requires large-volume chemical agents across all production stages to drive and optimize overall processes. Condensate water and boiler water treatment constitute critical procedures, as any deviation may exert a direct impact on power generation. Proper chemical water treatment can maximize the uptime of cooling towers and boilers, thus cutting operating costs and ensuring process optimization.
LEIGAO metering pumps and dosing systems feature high reliability, with proven expertise and successful track records in efficient chemical transfer and continuous operation.
