• 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 airflow into the spaces.
• High thermal performance with reduced consumption: The 760 W motor moves an air volume of 22,000 m3/h, ensuring very low energy and economic consumption compared to compressor air conditioning systems.
• Resistance and unalterability in chemical environments: The specific frame with UV and corrosion resistance allows for fixed outdoor installation or in artisanal 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 top up the 140-liter tank.
• Prevention of lift pump failures: The integrated system activates automatic shutdown due to 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 panels 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 recovery after a black-out: The automatic restart function keeps the operating status in memory, turning the unit back on with the same operating settings as soon as the 230V power supply is restored.

This 140-liter portable cooler finds its optimal application in summer air conditioning and air circulation within outdoor environments, industrial warehouses, mechanical workshops, artisan laboratories, large warehouses and large domestic spaces. Thanks to the air flow rate of 22,000 m3/h and the mobility allowed by an empty weight of 56 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 machines in operation.

The h923_12 model is the right choice when the thermal management plan or company specifications require a powerful evaporative cooler (22,000 m3/h) with a large 140-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 a high air exchange rate, as the natural exchange technology on cellulose panels with a 760 W motor lowers 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 pump dry-run protection systems and fixed overall dimensions (1120X690X1700 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 chemicals?

Unlike traditional air conditioners that recirculate the same air, accumulating pollutants, the h923_12 cooler forces ambient air through its wet cellulose panels. 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 circulation in the rooms, providing for the simultaneous removal of fumes, odors and heat produced by running machines, adapting perfectly even to artisanal 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 water in the tank before it is pumped onto the cellulose panels, ensuring a healthy airflow. 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 panels and the air filter are easily removable and washable; the use of clean water is essential, as the use of water not coming from clean sources does not guarantee healthy air.

How is the water supply managed and what happens if the water in the 140-liter tank runs out?

The h923_12 cooler offers a dual configuration: it can work autonomously using the large 140-liter water tank, or it can be connected directly to the water network via the specific direct water connection with 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 shutdown for lack of water, immediately stopping operation to protect the lift pump from failures or overheating.
