Gardner Denver Refrigeration Dryers

High quality compressed air

GDD-series Non-Cycling Refrigeration Dryers

Energy efficient refrigeration dryers

First-class air treatment efficiency

For Gardner Denver, quality and efficiency are just as important for compressed air treatment as they are for compressed air generation. Just like Gardner Denver compressors, the GDD-series refrigerant dryers also provide a consistently high performance with optimum efficiency for many industrial compressed air applications. They are carefully selected depending on working conditions with continuous dew point monitoring enabling reliable operation with the lowest possible pressure losses and running costs. When it comes to compressed air treatment, modern, reliable technology and compact dimensions make the GDD-Series the preferred choice for every application.


Investment protection through compressed air quality

Modern production systems and processes demand high quality compressed air, which is defined in the 6 classes outlined in international standard ISO 8573-1:2010 as illustrated in Brochure. These are only achievable with filtration, water separation and drying. Users in the food and pharmaceutical industry must adhere to stringent compressed air quality guidelines, as well as local legislation. Other industries may also follow specific advice regarding, the quality compressed air they use to ensure the protection and efficiency of process equipment and finished product.
