Moisture is the content of water present in the air. Humidity can affect the quality of stored products and their marketing conditions. Certain storage or production processes require a very low and controlled humidity level. Moisture can contribute to the acceleration of corrosion processes in metals and generates condensation and puddles that can affect the safety of people in their jobs. Condensation at temperatures below 0ºC generates frost and ice that reduces the efficiency of refrigeration equipment, malfunction of access doors, poor visibility due to fog in the chamber and false detections in automatic pallet handling systems.

The Aisproyec Group solves these problems with its exclusive AP-POWERDRY dehumidification technology.

The AP-POWERDRY desiccant rotor dehumidification technology consists of treating the air by passing it through a micro-perforated silica gel disc. All airborne water is retained on the disk. The water particles are expelled outside through the rotor regeneration process.


Each facility has humidity requirements for its processes. The humidity control is dimensioned according to parameters such as volumetric air to be treated, desired humidity conditions, estimation of air infiltrations, geographical location, external environmental conditions, level of tightness and insulation of the facilities as well as number of accesses, their dimensions and opening maneuvers. The Aisproyec Group has an extensive range with which to cover different work flows.

If it doesn't exist, we create it

If your need is not covered by our range of machines, our engineering team will collect all the necessary data to calculate and size the installation as well as the most suitable machine for your needs.

Total control electronics

Our machines have a state-of-the-art electronic control system that differentiates us from our competition.


A friendly human-machine interface.
Greater reliability and durability of components.
Ease of regulation.
Detection of faults and alarms.


Regeneration Temperature Control with PID controller with Autotuning. Maximum energy efficiency.
Exclusive design of the regeneration chamber that makes it a machine with high energy efficiency.
Touch screen for monitoring, configuration, alarm viewing and preventive maintenance indications.
Activation of the regeneration resistors by solid state contactors. Greater durability of the resistors and the drive. Lower maintenance costs.
Speed control of the fans by frequency inverter for a better adjustment of the installation.
Possibility of connection to Ethernet configuring a complex network of machines with centralized control.
Inductive sensing, humidity and temperature sensors ensure our machines run at full capacity.


If your installation has steam or natural gas installations or even excess heat that is discarded, at the Aisproyec Group we propose solutions for energy use with heat recuperators, economizers, the use of gas regeneration systems and the use of water vapor that ensure better efficiency of our equipment.
Consult our engineering team and we will offer you the best solution.


Our machines are easy to install but even easier to start up and regulate. In any case, our S.A.T. will be happy to assist you and provide you with quality after-sales service.

The AP-Powerdry machine is ready to operate 24 hours a day, 365 days a year. The reliability of our products is paramount. This does not mean that it requires high maintenance costs. The main maintenance task to be carried out is to check the status of the filters and their replacement when they become saturated. The life of the drying disc with proper use of the machine can be more than 8 years.
