Our air dehumidifying equipment use the adsorption method where moisture is removed from compressed air by desiccants (e.g. activated alumina, silica gel, synthetic zeolite, etc.).
Desiccant air dehumidifying equipment work by drying and regenerating the desiccant during the on-line cycle after it has adsorbed moisture.
We incorporate energy-saving designs in this heated regeneration process to minimize environmental impact as well as operating costs.
- Installing a cooling system at the inlet of a heated dehumidifying equipment to pre-treat the compressed air will reduce the amount of purge air as well as power needed to regenerate the desiccant.
- Use of a dew point meter to control the dehumidifying equipment cycle operation can extend the cycle period in winter when inlet temperatures are low or when only a small volume of airflow (intake) is required. This reduces the frequency of adsorbent regeneration, resulting in lower purge air consumption on top of less power needed for desiccant regeneration.
- Use of waste heat from the compressor for regenerating the adsorbent instead of electricity or steam can save on utility costs.
- Operating the regeneration cycle during late-night hours when electricity rates are low can reduce running costs dramatically.
