Refrigerated compressed air dryer KD series

water-cooledmedium-size

Product Overview
These water-cooled refrigerated air dryers are offered in two subseries (KDL and KDH) and use a plate heat exchanger for efficient air cooling. Detailed cooling-water, air-connection, power, dimensions and weight data are provided per model.

How It Works & Product Features
