Condensation air dehumidifier

AD 40
450 m³
35 l/24 h

Energy-saving dehumidification according to the heat pump principle. The AERIAL® AD 40 – light and compact

Our new condensation air dehumidifier is available in the modern and practical AERCUBE® housing. So light and compact that the AERIAL® AD 40 can be easily carried just like a suitcase. The AERIAL AD 40 dehumidifier comes with a handle that folds up. Lashing straps can be attached to the sides. The water-collection tank is located inside the dehumidifier. A float measures water levels in the water-collection tank and will switch off the dehumidifier when the tank is full. The unit starts up automatically when the bucket is reinserted and after a power cut.

Application areas for this product
Drying of water damage

for pipe breakage, flooding and the use of extinguishing water

Drying of new buildings

Protection against later humidity damage due to remaining humidity

Renovation of existing buildings

Shorter drying periods during the construction phase

Optimal indoor environment in living areas and cellars

Air humidity determines in a special way whether you feel comfortable in a room. Too high humidity can be oppressive and uncomfortable. It can cause mould and damage the building structure long-term. Visible or hidden mould in living areas can also have serious consequences for health.

Wellness areas in residential buildings

Private spa and wellness areas create increased humidity in the rooms used due to the vaporisation of warm water e.g. from pools. This creates a clammy, unpleasant atmosphere which can also put a strain on your circulation. A controlled dehumidification is good for your health and reduces the risk of corrosion or mould formation.

Protection of investment in vintage cars

Storage at too high humidity means that vehicles can suffer from metal corrosion, mould on leather and fungus infestation in wood parts. Replacement parts for vintage cars can be difficult to obtain and expensive. Restoration takes a lot of time and incurs additional costs. As a result, such valuable vehicles should be protected from humidity in good time. The AERIAL® air dehumidifier is ideal for just that.

Water management facilities

In Germany alone, more than 800 water plants and water management facilities place their trust in AERIAL® air dehumidifiers. Our equipment regulates humidity and thus protects pipes and control panels against corrosion. We offer competent and tailored expert advice on site and the right device for every room size.

Wind turbines

In the energy economy and in Renewable Energies, AERIAL® air dehumidifiers are used to prevent facility and transformer downtime due to too high humidity and corrosion damage to sensitive components. A controlled room humidity also contributes to improving the dielectric strength of insulators and increasing operating safety.

Food industry

Some processes in food production require a dry process and ambient air. Humidity greatly impacts on how long end products last, how they look and what they taste like. When handling natural raw materials, the process chain must be protected at all times to ensure that no germs or other pathogens can occur.

Pharma industry

Air humidity plays an important role in some processes in the pharma industry. Processing and storage of raw materials, preliminary and end products can strongly depend on the consistency and viscosity of these usually hygroscopic substances. 

Agriculture and husbandry

After the harvest, some agricultural products are subjected to a drying process for use, storage or further processing. AERIAL® dehumidifiers can ensure safe and dry storage to avoid loss through mould infestation or storage.

Museums, churches and collections

Museums, churches and collections are usually subject to special climatic requirements. Hygroscopic materials such as paper, canvases and paints can change or disintegrated if they are exposed to climatic fluctuations or a too high air humidity. 

Swimming pools, fitness and wellness areas

Leisure facilities with larger pools or wet zones face the challenge that the water turns into steam at higher temperatures. In this way, the air slowly becomes saturated with humidity which condenses on cold walls and windows. This condensate leads to rot, mould formation and corrosion.
