Wittmann introduced an energy rating standard developed for dry air dryers
Many resin dryer manufacturers promote their units as being highly efficient and offering energy savings of 50% or more. However, when asked "How much energy does the dryer consume?" or "What is the basis of the energy savings?" there is often little data to support their claims. What the industry really needs is a standard test protocol for measuring dryer energy consumption. In the spring of 2008 Wittmann introduced exactly that.
