Ideal for Etching Machine Liquid Cooling

This OWP-BL43-426C Electric Coolant Pump is specifically engineered for liquid cooling systems in etching machines, serving as a critical component for maintaining stable etching operations. Etching machines generate substantial heat during plasma etching processes—driven by high-frequency electric fields and intense ion bombardment—particularly affecting key components like the etching head and reaction chamber. Uncontrolled heat can lead to unstable etching rates, potential equipment damage, and compromised semiconductor product quality.

The pump effectively addresses these challenges by efficiently circulating cooling media (such as 50-60% glycol-water or electronic fluorinated solution) through the etching machine's cooling circuit. It ensures consistent heat dissipation from the electrostatic chuck (ESC) and reaction chamber: by maintaining the ESC at precise temperatures, it guarantees uniform etching rates across the wafer; by stabilizing chamber wall temperatures, it controls fluctuations in etching selectivity. With a high flow rate (up to 5000L/H) and maximum lift head (20M), the pump enables rapid heat transfer even in complex cooling loops, while PWM speed regulation allows real-time adjustments to match the etching machine's dynamic heat output—ensuring optimal cooling performance throughout all operational stages.
