According to Bryan, soaking out a part to 20 C using high-velocity air takes significantly less time than in still air. Liquid showers are 10 to 20 times more effective than air showers. All of the experts interviewed agreed that controlling temperature is the most effective way to attack thermal problems. All in all, it means zapping errors before they start. Bryan suspects that people consider the concept, then talk with friends who shoot down the idea.
Most people believe it's too expensive or unrealistic.
What they don't realize is that only one step is needed for temperature control, according to Bryan. He explained that most machine tools come with boxes, because the Environmental Protection Agency requires them for safety. The boxes are generally equipped with coolant systems, which are not temperature-controlled. If a supply of chilled water is available, the coolant can be controlled economically with a heat exchanger and thermostat. Nonetheless, manufacturers usually have boxes, plus coolant to drive the liquid or air showers.
