Ideal for environments up to 400 m²
G4 Dust Pre-filter

The Kaltermann KM30 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 molds, 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 worker health, and a safe and efficient working environment.

The KALTERMANN KM30 cooler uses an evaporative cooling system. Hot air is drawn into the device and passed through a wet panel, which naturally lowers its temperature.
Unlike traditional systems, it does not use chemical refrigerants, offering an ecological, sustainable, and low environmental impact solution.
By harnessing the natural process of water evaporation, the device releases a flow of fresh and pleasant air into the environment, improving comfort efficiently and naturally.
The KALTERMANN KM30 cooler is designed for immediate use thanks to the Plug and Play system: it requires no complex assembly or additional installations. Simply plug it into the electrical outlet, and the device is ready to operate, 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 is easily inspectable and replaceable in a few steps independently.



Pureflow filtration technology features a patented filtration and purification technology that significantly improves the performance and lifespan of mobile adiabatic coolers, even in environments with high dust concentration.
This Kaltermann KM30 cooler has a G4 filter which guarantees 90% efficiency on particles from 100 μm.

Pureflow with G4 filter is specifically designed for use in dusty environments with high levels of airborne impurities.
It ensures the protection of the cooling system by shielding it from dust and increasing its performance and durability.

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

Kaltermann KM30 uses technology that minimizes energy consumption compared to traditional cooling systems, making it a sustainable choice. Its power is 850 W with an airflow of 30,000 m³/h. KALTERMANN KM30 is designed to operate at relatively low noise levels (66-70 dB), making it suitable for work and commercial environments. Maintenance is minimal, thanks to easy access for filter cleaning and water management.
Its water capacity is 280 L with a water consumption ranging from 20 to 30 L/h.

N.B. to achieve the highest possible efficiency from the cooler, it is important that the environment is adequately ventilated
Thanks to its ability to cool large areas up to 400 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 vehicles are worked on, as they can reduce heat without compromising air quality.
The mobility and ease of installation make the KM30 particularly suitable for cooling temporary spaces, such as fairs and outdoor events, where climate management is a priority.
In these environments, the temperature can become high, so a cooler like the KM12 allows for natural heat reduction, protecting crops and improving agricultural work.
These coolers can also be used in more sensitive environments, such as livestock farms. In these cases, the coolers should be placed at the entrance of the barn to ensure that the incoming air is not contaminated by internal dirt.




It is possible to choose to equip the Kaltermann KM cooler with a metal filter. This filter is specifically designed for use in particularly dusty areas, such as workshops with oily mists and environments with a high presence of dust, like woodworking shops, stone processing, and similar.

This Kaltermann product is covered by an extended 5-year warranty.
Please note that consumables like UV lamps and filters are excluded from the warranty.
