Application in Semiconductor Wafer Fabrication Equipment Cooling

The OWP-BL43-450T Electric Coolant Pump is specifically optimized for heat dissipation in semiconductor wafer fabrication equipment, where precise temperature control directly impacts wafer yield and performance. Its 6000L/H rated flow rate (at 8M head) and 9000L/H maximum flow ensure efficient circulation of compatible cooling media—including glycol-water mixtures, dielectric oil, and electronic fluorinated solutions—to dissipate heat from lithography, etching, and deposition tools. The 24VDC wide voltage input (18-32VDC) aligns with semiconductor factory power systems, while the 38mm outlet diameter facilitates high-volume fluid transfer for effective heat exchange. PWM speed regulation allows the pump to adapt to varying thermal loads during wafer processing, maintaining consistent temperatures within tight tolerances. The IP68 waterproof rating and -40℃ to 85℃ temperature range ensure reliability in controlled fab environments, while fault feedback signals enable integration with factory monitoring systems. As a core cooling component, the OWP-BL43-450T supports the demanding thermal management needs of semiconductor wafer fabrication equipment, contributing to stable production and high-quality wafer output.
