Micro-heat regenerative adsorption dryer is an energy-saving product designed and developed by our company, which has reached the domestic advanced level. This series of products combines the advantages of heat regeneration and heatless regeneration, and adopts the form of slight heating for the regeneration gas, so as to reduce the consumption of regeneration gas and achieve the purpose of energy saving.

It avoids the disadvantage of short switching time of heatless regenerative dryers and also avoids the disadvantage of large power loss of heat absorbing dryers. It is an economical energy-saving adsorption dryer in the purification industry at present and is widely used in metallurgy, electric power, Electronics, food, chemical, petroleum, pharmaceutical, tobacco, instruments, meters, and automatic control industries.

»Working principle

This series of drying machines combines the advantages of pressure swing adsorption and temperature swing adsorption. Adsorption (work) at normal temperature and high water vapor partial pressure: analysis (regeneration) at higher temperature and low water vapor partial pressure. That is, the moisture adsorbed by the adsorbent during the adsorption process can be completely removed during the regeneration process by the joint action of the thermal diffusion of the high-quality regeneration gas (heated by dry air) and the high-pressure difference.
