High Efficiency Adsorption Dryers, Extra Dry –
January 1st 2007 Around 80 per cent of the energy from a compressor is lost in the heat generated in the compression process, which the vast majority of operators simply throw away. The HCR dryer recovers that heat and utilises it in the regeneration of the desiccant bed. This is both energy efficient and cost effective, as in many installations compressor heat energy is the undesirable byproduct of generating compressed air. In many instances it is merely expelled into the atmosphere where it is not only wasted, but contributes to the level of contaminants present and global warming. Combining energy efficiency with low energy costs, Donaldson Ultrafilter's 'zeroloss' dryer technology for compressed air and gases offers a range of air dryness to suit particular applications, according to dew point and inlet temperature requirements. The heat regenerated adsorption dryers use no system compressed air in the cooling process whatsoever, eliminating expensive losses. On electric heat regenerated dryers, Donaldson Ultrafilter was again first to introduce heater installation out-side the vessel, facilitating ease of maintenance Similarly, the company introduced steam regeneration for installations such as paper mills, dairies, breweries and the pharmaceutical industry, where steam is often readily available as a by-product. Donaldson Ultrafilter is committed to innovative research and development and to the production of energy efficient, environmentally friendly systems. Combining these systems with the fullest range of Donaldson Ultrafilter filtration products ensures validated performance to all relevant ISO standards.
