The Kaltermann KM48 air cooler is equipped with an integrated antibacterial UV lamp , which adds an extra level of protection for the health of the environment.
This technology disinfects water and air , eliminating bacteria, viruses, fungi, and mold , ensuring a healthier and safer environment. Ultraviolet light works by destroying the genetic material of microorganisms, preventing their proliferation and improving the quality of the air released into the environment.
Particularly suitable for industrial environments or work areas, this system guarantees cleaner air , protection of workers' health and a safe and efficient working environment .

The KALTERMANN KM48 cooler uses an evaporative cooling system. Warm air is drawn into the unit and passed through a damp pad, which naturally lowers its temperature.
Unlike traditional systems, it does not use chemical refrigerants , offering an ecological, sustainable and low environmental impact solution .
By exploiting the natural process of water evaporation, the device releases a flow of fresh, pleasant air into the room, improving comfort in an efficient and natural way.
The KALTERMANN KM48 cooler is designed for immediate use thanks to the Plug and Play system : it requires no complex assembly or additional wiring. Simply plug it in and the device is ready to go, ensuring quick and intuitive installation even for those without technical expertise.
The water tank can be filled manually or connected directly to the water mains , thus offering continuous autonomy without interruptions.
The filter can be easily inspected and replaced in just a few steps.



Pureflow filtration technology features patented filtration and purification technology that significantly improves the performance and lifespan of mobile adiabatic coolers even in environments with high dust concentrations .
This Kaltermann KM48 cooler has a G4 filter which guarantees 90% efficiency on 100 μm particles .

Pureflow with G4 filter is specially designed for use in dusty environments with high levels of impurities in the air.
It ensures the protection of the cooling system by protecting it from dust and increasing its performance and durability over time .

The G4 pre-filter is designed to provide effective protection against dust and impurities in the air. Classified as ISO Coarse , this filter is capable of blocking particles larger than 100 μm .
Strategically positioned at the system entrance, it prevents impurities from entering the cooler, thus ensuring greater efficiency , performance and long life of the appliance.
Perfect for industrial environments and dusty work areas , improving operator health and safety .


The Kaltermann KM48 uses technology that minimizes energy use compared to traditional cooling systems, making it a sustainable choice. Its power is 1200 W with a flow rate of 48,000 m³/h . The KALTERMANN KM48 is designed to operate at relatively low noise levels (73-78 dB) , making it suitable for office and commercial environments. Maintenance is minimal, thanks to easy access for filter cleaning and water management.
Its water holding capacity is 350 L with a water consumption that varies between 20 and 25 L/h .

NB to obtain the greatest possible efficiency of the cooler it is important that the room is adequately ventilated
Thanks to its ability to cool large surfaces of up to 500 m², it is ideal for work environments where thermal efficiency is essential, but without the use of complex and expensive air conditioning systems.
In industrial environments, where dust can be a problem, the G4 pre-filter helps keep the air clean, protecting machinery and improving worker comfort.
KALTERMANN evaporative coolers are also useful in environments where materials are stored or work is done on vehicles, as they are able to reduce heat without compromising air quality.
Its mobility and ease of installation make the KM48 particularly suitable for cooling temporary spaces, such as trade fairs and outdoor events, where climate management is a priority.
