working principle
The adsorption dryer utilizes advanced chemical technology, which operates by utilizing the difference in moisture and air molecule volume between saturated compressed air. It uses gas purification specific molecular sieves to adsorb saturated water vapor from the compressed air,

It is easy to adsorb water molecules into the molecular sieve particles, and then use regeneration methods to reduce the molecular sieve, so that its compressed air dew point can easily reach -40C.
SPE technology features
SPE type micro heat regeneration adsorption dryer is a product developed by absorbing the advantages of both hot regeneration and non hot regeneration methods. The regenerated gas regenerates the desiccant after increasing the temperature, which can improve the regeneration effect and reduce the regeneration gas consumption;
Its characteristics are mainly different from the non heat regeneration adsorption dryer in that it has a safety protection function for reheating gas.
