Dryer, Filter, and Drain in One Compact Package
Kaeser High Temperature Refrigerated Dryers (HTRD) are specifically designed for use with 5-25 hp piston compressors, although they will work well with any similar sized compressor producing high discharge temperatures. The HTRD contains an aftercooler, refrigeration unit, filtered separator and drain to remove moisture and contaminants to a level suitable for most shop tools. This greatly increases tool life, reducing maintenance and downtime, for paint spraying applications we strongly recommend also using a KOR model coalescing filter.
Easy to Install
The HTRD dryer features a compact design that requires little floor space and allows for convenient installation. Staggered inlet/outlet connections make piping easy. Simply make pipe connections and plug in the electrical cord to a 120 V or 230 V depending on model, 1 phase outlet and the unit is ready for operation.
Easy to Use and Maintain
The dryer operates continuously without adjustments. Replacing the filter sleeve is simple and cleaning the refrigeration condenser filter and inlet strainer is easy to accomplish.

All dryers are CSA certified, CFC free, and use environmentally friendly R407c refrigerant.
Five-year warranty on heat exchanger.
Two-year warranty on refrigeration system.
