Problem and Need

Often industrial processes, the processing of materials or the storage of food require a dry environment. Sometimes the dry air needs to be available below freezing point, at very low relative humidity or at highest hygiene. For this goal today a silica gel based technology is used that works unfortunately very energy intensively.

Solution and Advantages

The technology of AquAero can be shaped in function of a dehumidifier. In the application of the dehumidification of cold storage rooms or to produce air of quiet low relative humidity compared to conventional silica gel technology only half of the energy demand is required to reach the same air conditions. The process purity equals the results of steam sterilization. Highest requirements for hygiene are met at highest energy efficiency.

What are the differences compared to conventional technology?

Today for dehumidification there are two main principles:

The principle of condensation: To dehumidify in hot humid conditions the air can be simply cooled to condense the water. This principle is only utile as long as the temperature is considerably higher than the freezing point and hygiene is not of importance.

The principle of adsorption: Is the temperature close to the freezing point, the air shall be dehumidified strongly or the hygiene need is high, the principle of ad- and desorption with silica gel is used. Nevertheless because of the physical facts this principle works without energy recuperation. It is concluded that this system meets the conditioning of the air and the need for hygiene but lacks any enhanced energy efficiency.

The technology of AquAero is able to fulfill these three points: Air conditioning, the hygiene need and the energy efficiency at the same time. Thus, roughly half of the energy cost can be saved.
