PAE 51 air cooler
Coldness from natural evaporation for hot summer days
Enjoy the summer to the full with a cool refreshment
Can be used virtually everywhere. Indoors and outdoors. Light and portable.
At the push of a button, Trotec's air cooler PAE 51 brings instant, agreeable cooling and turns heated office and living spaces into climatic temples of well-being. When the thermometer climbs to temperatures of over 25 degrees, both mental and physical performance start to decrease. At night, excessive temperatures keep us awake and prevent us from getting the necessary rest to recover from the day's exertions.
A healthy room climate without side effects
The PAE 51 serves to cool, ventilate, refresh and humidify the air.
Unlike an air conditioning system the air cooler PAE 51 does not reduce the room temperature by means of refrigerants, instead it makes use of the natural principle of evaporation resulting in the desired cooling effect. For this cooling process the device needs fresh tap water that is filled into the 20 l water tank. The integrated evaporation filter with honeycomb structure humidifies the sucked-in air and then discharges it as cold air through the fan. This chilled air current provides cool refreshment that is immediately noticeable on your skin.
Our recommendation: The water for filling the evaporative air cooler should be as cold as possible. Use ice packs or ice cubes for an additional cooling effect.
Healthy breathing to increase your well-being! Owing to its integrated air filter the PAE 51 can be used as humidifier and air freshener all year round. Especially in the dry winter months this can help to reduce the risk of catching a cold which is often promoted by dried-out mucous membranes from the dry heated air.
Enjoy pleasant refreshment! You can also find all the relevant information about our comfort air conditioning units in the product brochure. Download the PDF directly here.
Increasing the humidity level to 50 % reduces the risk of transmission of viruses
Medical specialists have evaluated research findings relating to the resistance of viruses (e.g. SARS-CoV, MERS-CoV or SARS-CoV-2 (Covid-19), influenza) to air humidity. These findings have revealed that the humidity level has a crucial impact on the infectivity of germ droplets. Dry room air with a relative humidity content of less than 40 % lets tiny droplets infected with influenza or cold viruses dry up. This preserves pathogens so that they remain infectious for a very long time. In the optimum relative humidity range between 40 and 60 % aerosols only shrink so far that the salt concentration in the aerosol core increases, causing the germs and microorganisms contained to be killed. This minimizes the risk of an infection with influenza and cold viruses.
Medical specialists emphasize that we are able to reduce the risk of infection by increasing the humidity level in buildings. In this way, increasing the humidity level to approx. 50 % by humidification will reduce the risk of transmission. Moreover, the humidified air improves the body's defence situation by more efficient cleaning of the air passages and an improved immune defence. In modern buildings with a watertight building envelope, central heating and ventilation systems, these limit values can often not be complied with in everyday life without active humidification. This is where devices with a humidification function come in to provide assistance.
Customised feel-good climate and a healthy rest
Adjust the cooling intensity to your individual requirements.
The decision regarding intensity and flow direction of the distributed air is completely up to you. The device is equipped with 4 fan stages, manually adjustable ventilation flaps an optional on-demand swing function for the automatic distribution of cold air in the room.
You wouldn't mind a fresh breeze? The natural wind mode can revitalize you with an additional boost of freshness. The alternately rising and subsiding ventilation intensity is based on natural winds and ought to have the same invigorating effect. For an extra dose of freshness available at the push of a button.
A good night's rest is enabled by use of the ultra-silent night mode and timer function that has the air cooler switch off automatically after a freely selectable period of time. All settings are either made via the LED-lit control panel at the device or using the supplied infrared remote control.
With an hourly evaporation performance of 2 litres and an air flow rate of 661 m³/h the PAE 51 is particularly well-suited for use in rooms sized up to 150 m³. Chilled calculators will appreciate the low energy consumption of merely 110 watts as well as the consequently also low operating costs.
Natural cooling principle
In contrast to air conditioners, air coolers do not use any chemical refrigerants. The cooling effect is generated in a natural manner. Moreover, neither an exhaust air hose nor any elaborate installations are required.
A mobile air cooler works on the principle of natural evaporation cooling. As you probably know from your own experience, blowing on moist skin creates an instant feeling of refreshment as the evaporation process withdraws warmth. Air coolers work in the same way: in the interior of the air cooler there is a water-soaked filter mat using. The warm air is directed from the rear of the device through the wet filter mat and in passing is cooled down due to the evaporation effect. The now colder air is then blown back into the room by the fan.
Can be operated all year round – air cooler in the summer, humidifier in the winter
With the PAE 51 you can enjoy mobile feel-good climate throughout the year. We recommend using the slim air cooler in space-saving design throughout the year rather than parking it in a storeroom when the summer ends. In the spring and late summer its 4 fan stages can provide a fresh breeze so that you can enjoy the cooling effect of the cold evaporation.
In autumn and winter the device is furthermore well-suited as an effective humidifier, in order to create a more pleasant room climate. Since dry heated air can irritate the respiratory tract, dry out the skin and cause red eyes. Moreover, the multiplication of viruses within the room air is reduced at a humidity level of 50 %. By using a humidifier you provide for a sufficient humidity level and in this way can improve your own well-being in sticky, overheated rooms as well as prevent colds and virus infections.
With the 4-in-1 air cooler PAE 51 you benefit from pleasant air cooling, refreshing ventilation and agreeable humidification. For a perfect climate throughout the year!
Continuous fresh water supply to ensure a healthy air quality.
To automatically keep the water storage tank as clean as on the first day, we recommend using a SecoSan-Stick which keeps the water permanently clean, clear and free from germs or unpleasant odours. The unique feature of SecoSan is its antimicrobial surface with mobile silver ions, which inhibit bacteria and germs upon contact and thus prevent their reproduction. The entirely self-dosing SecoSan ion reservoir keeps the water demonstrably free from germs. The stick thus guarantees clean water for up to 6 months even if the water is changed or consumed daily.
Using air coolers as humidifiers during the wintertime
Air coolers are most effective in rooms filled with dry air. Just like humidifiers these devices operate based on the evaporation principle, i.e. they directly supply the air with cool moisture. This means that for process-related reasons the humidity level in the room is increased perceptibly. During the winter this increase of humidity is beneficial to the mucous membranes. As a result you might be able to avoid catching a cold that is largely caused by the dry heated air. The practical and optically attractive thermohygrometer BZ20M in cross-needle design shows you at a glance when the humidity level is in the optimum range.
