ALD-Holcroft successfully installed and commissioned a four-chamber ModulTherm® system – the first of three systems all to be located with the same manufacturer in the Midwest. This ModulTherm system operates using recipe-selectable helium or nitrogen high-pressure gas (up to 20 bar) for quench and incorporates pre-wash, pre-oxidation, convection heating and tempering in a fully automated, lights-out system. When helium quench is selected, it is captured and reclaimed at the rate of 99.5% per quench. Equipped with Dynamic-Quenching® and multi-directional quench gas control, this system provides the best possibilities for control of workpiece distortion.
