Protection of grounded aircraft

Dehumidification efficiently protects grounded aircraft from moisture related damage on a short or long term basis and ensures operational readiness for airlines and airports around the world.

The world’s airlines have been hit hard by the Covid-19 pandemic.  Many aircraft have been grounded indefinitely, and are now at significant risk of costly damage from moisture related issues such as condensation, mould and corrosion. 

Munters' solution

Fleet owners, aircraft owners, national airlines and maintenance hubs at airports can all benefit from finding the right climate control solution for their needs and Munters has global experience on preservation of grounded aircraft, military as well as civil. 

By protecting the interior of the grounded aircraft by means of Munters dehumidification, the humidity within the cabin will be lowered and fully controlled. Maintaining the relative humidity at a low level, irrespective of the outdoor fluctuating conditions, the cabin incl. seats, carpets, electronics will be effectively protected against any humidity related damage.









Significantly reduce unnecessary and costly aircraft maintenance by preventing condensation, mould and corrosion.




Prevent costly and often irreparable damage to the internal fabric of the aircraft




Protect against corrosion and damage to avionics and electrical systems



Air craft

Help ensure grounded aircraft are operational and ready to fly when needed







How does it work?

  • Packaged system that can be delivered directly to site
  • Flexible - units available for purchase, or short or long term rental.
Air craft turbine Small Air craft turbine

Protection of turbines

For protection of smaller turbines a so-called ”fresh air solution” is recommended. Dry air from the dehumidifier is lead to the turbine and the wet air exits the turbine into the open. For bigger turbines the wet air is returned to the dehumidifier’s dry air inlet, in a so-called “return air system”. This principle will increase both energy efficiency and dehumidification capacity.

Protection of aircraft interior

The dehumidifier is placed centrally in the cabin. By means of the extraction fan in the dehumidifier, the humid air from the cabin enters the dehumidifier and the humidity is absorbed by the desiccant wheel (rotor).  The dry air leaving the rotor is distributed within the cabin via flexible ducts along the aisle, typically under the seats. This allows for efficient protection of all parts of the cabin. The in- and outlet for the air used for the regeneration of the rotor can be lead to the open air via an opening in a window, e.g. in one of the doors of the aircraft.
