2. Primary Application: Lithography Machine Liquid Cooling Systems
A key use case for the OWP-BL43-426C Electric Coolant Pump is lithography machine liquid cooling, a critical application where precise heat dissipation directly impacts chip manufacturing quality. Lithography machines generate significant heat from components like laser light sources, projection objectives, and precision worktables—even tiny temperature fluctuations can cause optical element deformation or laser wavelength drift, leading to reduced chip yield.
The OWP-BL43-426C addresses these challenges by delivering consistent, high-volume coolant flow (up to 5000L/H) and stable lift (max 20M), ensuring efficient heat transfer across sensitive lithography components. Its compatibility with cooling media like glycol-water mixtures and dielectric oil allows it to adapt to different lithography machine cooling requirements, while PWM speed control enables real-time adjustments to match heat output changes. With an IP68 rating, it also withstands harsh industrial environments, preventing coolant leaks or pump damage that could disrupt production.
