Professional dehumidifier Nader Yard PRO

design and efficiency

The professional dehumidifiers of the YARD series are refrigeration circuit units that, introduced into the room to be dehumidified, recirculate the air gradually lowering humidity to the desired value. Decreasing the humidity of the air gradually subtracts moisture also from the walls and all the materials contained in the room. All machines operate with ecological cold gases, according to the latest European regulations.

The NADER YARD PRO, with its very high dehumidification capacity of 80 L/24h, is dedicated to the most demanding situations and where rapid dehumidifying action is required without compromise. Power and efficiency combined with easy transportability, overlay and ease of use.

Due to its very high dehumidification capacity, this model has no collection tank, but a practical attachment for the direct discharge pipe of condensed water, placed laterally to the machine and at a height of 35 cm from the ground.



High capacity

81 L/24h


The large diameter wheels allow easy movement even on rough terrain of construction sites, and the exclusive retractable handle can be easily folded reducing the bulk of the machine


The low consumption and use of ecological refrigerant gas make these devices extremely environment friendly.


All the machines have been carefully studied and tested, the individual components that make up the heart of the dehumidifier, have been selected to work efficiently and lastingly. The use of rotary compressors has allowed to reduce consumption and optimize performance, hot gas defrosting allows the dehumidifier to operate up to +2°C.


The new and modern control, together with the electronic humidistat, standard on all models, optimizes the use of the dehumidifier by making it work only when needed. The control panel has been placed in a convenient position and easily accessible by the user, who can set the desired degree of humidity through “soft touch” buttons. For maximum operator safety all controls are in low voltage. The dynamic defrosting function also minimizes the time it takes to remove any ice from the exchanger, a function necessary to keep the machine’s efficiency level high at the lowest temperatures. As standard, electronic control manages two counting, one resettable and one cumulative: indispensable and practical for rental.


Water subtracted from ambient air is collected in the tank (where provided) equipped with a float that stops the dehumidifier when it is full. In addition, the machines are prepared as standard for the installation of the continuous discharge: at the convenience of no longer having to empty the tank, the safety of the float is flanked, which in any case, in case of malfunction of the drain, will stop the full tank dehumidifier. The YARD PRO, given its high capacity, is not equipped with a tank but with a practical continuous condensate discharge system located at the height of 35 cm from the ground to facilitate the insertion of an adequate collection tank.


This component is available as standard on all models. The air filter prevents dirt from reaching the exchangers and therefore keeps the efficiency of the machine high over time. For cleaning the filter is easily disassembled: it can be cleaned with a vacuum cleaner, compressed air or, in the worst cases, even washed in water.


The machines can be customized on request. For example, the continuous condensate discharge pump is available, which allows you to evacuate water exceeding the difference in height even by a few meters. It is also possible to adapt the machines to particular customer needs to make them more compliant with their brand.
