As a so-called heat-of-compression (HOC) dryer, our high-performance DTC uses the compressor heat for regeneration. Generally, our HOC dryers are used in conjunction with oil-free compressors, which emit a higher compressor heat. However, FST offers different variants of the DTC, for example with booster heaters. With these highly efficient compressed air dryers, our customers can regenerate the desiccant even with lower compressor discharge températures.
