Applications
Professionally developed for rail transit industry heat dissipation of metro and light rail traction converters. These key power components produce significant heat during continuous operation, requiring efficient cooling to maintain normal equipment function.
This 400W rated power coolant pump provides strong cooling support with 3000L/H rated flow and 5000L/H maximum flow capacity. It stably conveys various cooling media including glycol-water mixture, dielectric oil and electronic fluorinated solution within -40-85℃ temperature range, adapting to complex rail transit operating environments.
IP68 protection grade ensures resistance to dust and moisture for both on-board and trackside installation. With over 20,000 hours service life, it reduces maintenance requirements for urban rail transit lines. PWM speed regulation and fault feedback functions enable intelligent cooling system monitoring.
