• Continuous sanitization of the water tank: The bactericidal UV lamp actively disinfects the water before the evaporative cycle, ensuring the constant introduction of a healthy air flow into the spaces.
• High thermal performance with low consumption: The 750 W motor moves an air volume equal to 38,000 m3/h, ensuring very low energy and economic consumption compared to compressor air conditioning systems.
• Resistance and durability in chemical environments: The specific frame with UV and corrosion resistance allows the module to be permanently housed outdoors or in craft factories exposed to chemical agents without risk of deterioration.
• Continuous water autonomy without interruptions: The direct water connection via hose manages automatic filling in combination with the level control, eliminating the need to manually refill the huge 300-liter tank.
• Prevention of lifting pump failures: The integrated system activates automatic shut-off for lack of water as soon as the liquid falls below the minimum threshold, safeguarding the integrity of the pump.
• Zero-cost routine maintenance: Both the cellulose evaporative pads and the air filter are easily removable and washable independently, allowing for the removal of dust and limescale without requiring the intervention of specialized technicians.
• Immediate parameter restoration after a blackout: The automatic restart function keeps the operating status in memory, turning the unit back on with the same operating settings as soon as the 220V power supply is restored.

This 300-liter portable cooler finds its optimal application in summer air conditioning and air recirculation within outdoor environments, industrial warehouses, mechanical workshops, craft laboratories, large warehouses and large domestic or commercial spaces. Thanks to the impressive air flow of 38,000 m3/h and the maximum structural stability offered by a weight of 180 Kg, it represents the ideal solution for operational contexts characterized by the presence of chemical substances, suspended dust or strong radiant heat, working effectively in all open or open-plan areas that cannot be delimited by doors or fixtures to favor the continuous removal of fumes, unpleasant odors and heat emitted by running machines.

The h923_16 model is the correct choice when the thermal management plan or company specifications require a professional evaporative cooler with maximum power (38,000 m3/h) and a large 300-liter tank, equipped with a control panel and UV water disinfection system. It proves to be widely preferable to traditional air conditioners in open contexts or those with high air exchange rates, as the natural exchange technology on cellulose pads with a 750 W motor reduces the temperature without the need for external ducting or masonry work. Choosing this plug and play device means investing in a durable machine, equipped with anti-dry pump systems and fixed structural dimensions (1960x980x2000 mm), designed to keep the air healthy and energy costs under control.

How does the recirculation action of this evaporative cooler differ in the presence of fumes or chemical substances?

Unlike traditional air conditioners that recirculate the same air, accumulating pollutants, the h923_16 cooler forces ambient air through its wet cellulose pads. During this passage, the air gives up heat to the water through evaporation and undergoes mechanical filtration thanks to the integrated washable air filter. This process ensures greater air recirculation in the rooms, providing for the simultaneous removal of fumes, odors and heat produced by running machines, adapting perfectly even to craft or industrial contexts with chemical substances.

What maintenance and precautions are necessary to ensure air healthiness in areas exposed to dust or limescale?

The unit is equipped with a bactericidal UV lamp that constantly sanitizes the tank water before it is pumped onto the cellulose pads, ensuring a healthy air flow. However, it is recommended to periodically sanitize the device, especially if the surrounding area has dust or if the water has high levels of limescale. The cellulose evaporative pads and the air filter are easily removable and washable; the use of clean water is fundamental, as using water not from clean sources does not guarantee healthy air.

How is the water supply managed and what happens if the water in the 300-liter tank runs out?

The h923_16 cooler offers a dual configuration: it can operate independently using the large 300-liter water tank, or it can be connected directly to the water mains via the specific direct water connection with a hose for continuous automatic filling managed by the water level control. If the tank is used and the water runs out completely, a sensor activates the automatic shut-off for lack of water, immediately stopping operation to protect the lifting pump from failure or overheating.
