Oil cooled spindle is the traditional cooling way for engraving machine. The most obvious advantage of oil cooling is to prevent the machine from rusting. But it's poor at heat conduction and in a high cost. Yet the greatest strength of water cooling is shown at excellent heat conduction, low cost and eco-friendly.
Chillers produced by S&A apply the way of water cooling, equipped with specially-made anticrustator to avoid rusting problem, ensuring effective heat exchange. S&A chillers deserve your trust.
