Wittmann has introduced a comprehensive testing program to establish energy ratings for their Drymax dry air dryers.
Wittmann has introduced a comprehensive testing program to establish energy ratings for their Drymax dry air dryers.
Developed after several years of research, this standardized rating method is based on stringent test conditions that provide repeatable results for the actual energy use. Traditionally, establishing the energy consumption for many plastics processing
products means using internal company measuring methods that naturally differ from each other, and can be overtolerant when it comes to interpreting data.
Wittmann’s system, in contrast, looks at internal moisture content of the resin and the ambient conditions, and uses airflow as the common property. This allows the company to define the actual energy rating as the basic energy consumption per mass flow of air.
To further test the validity of the result, Wittmann compared actual test results with theoretical values.
Once tested, every dryer model will be labeled with an Energy Sticker showing the measured test result in terms of kWh per unit weight of dry air.
