The heated desiccant air dryer can either regenerate heat or regenerate no heat. It can employ micro heating to the generated air to reduce the consumption and save energy. When compared with the heatless adsorption dryer, the heated desiccant air dryer has reasonable switching time, less loss of regenerated air and more efficient electric energy conservation.

The regenerative desiccant dryer is currently the most economical and energy-efficient compressed air dryer in the purification industry. Our heated desiccant air dryer can be also widely applied to a variety of industries, such as metallurgy, electric power, electronics, food, chemical, petroleum, pharmaceutical, textile, tobacco, instrumentation, automation, etc.
