Designed for surfaces up to 400 m² , it combines adiabatic cooling technology without misting with an effective filtering action against dust and fumes. Ideal for warehouses , workshops , greenhouses and sheds , it offers an ecological alternative to traditional air conditioning systems, reducing energy consumption and significantly improving comfort and air quality.
Thanks to its compact structure, silence and simple water management, the FRESH 150 stands out for its practicality and efficiency. Its use allows you to create healthier and more productive work environments, without invasive interventions or complex installations, perfectly responding to the needs of environmental sustainability and operational savings.
It is equipped with an F8 filter certified according to the EN779:2012 standard , indicated for retaining particles of a size equal to 0.4 microns with an initial efficiency of less than 98% , thus offering an ideal level of protection against fine dust, fumes and other pollutants.
Ideal for rooms up to 250 m²
F8 Dust Filter and G4 Prefilter

The Kaltermann FRESH 150 cooler is equipped with a built-in antibacterial UV lamp that offers an additional level of protection for the health of the environment. This technology is designed to disinfect water and air, eliminating bacteria, viruses, fungi and mold , ensuring a healthier 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. This system is particularly useful in industrial or work environments, where air quality is crucial to the health of workers.

The KALTERMANN FRESH 150 cooler is based on a simple but effective principle: evaporative cooling. When warm air is drawn into the device, it passes through a wet cooling pad, which reduces the temperature of the air without using chemical refrigerants, making it an environmentally friendly solution . In practice, the device uses the natural evaporation process of water to lower the temperature of the air which is then released into the room.

One of the distinguishing features of the KALTERMANN FRESH 150 is the G4 pre-filter , which offers effective protection against dust particles and other impurities in the air. The G4 pre-filter, classified as ISO Coarse , is designed to stop particles larger than 10 μm , such as sand and other large impurities. This makes it particularly suitable for dusty industrial and work environments, where maintaining clean air is essential for the health and safety of workers. Thanks to its position at the inlet of the system, the G4 pre-filter prevents these particles from entering the cooler , thus ensuring greater efficiency and durability of the appliance.
The F8 filter represents a high-quality solution for air purification in industrial environments, ensuring superior performance in the filtration of the finest particles. Certified according to the European standard EN779:2012 , the F8 filter is designed to achieve a high efficiency class, ensuring the removal of a large quantity of air contaminants. In particular, this type of filter is suitable for retaining particles as small as 0.4 microns with an initial efficiency of less than 98% , thus offering an ideal level of protection against fine dust, fumes and other pollutants. Thanks to these characteristics, the F8 filter is an excellent choice for improving air quality in contexts where purity is essential, contributing to the well-being of workers and the protection of machinery.
The G4 filter is ideal for blocking coarse particles such as dust and sand, acting mainly as a pre-filter. The F8 filter, on the other hand, captures much finer particles , such as fine dust and fumes, offering superior protection. In summary, the G4 is chosen for general dusty environments and the F8 for areas that require cleaner and safer air.


Designed for industrial and commercial environments, the Kaltermann FRESH 150 cooler is particularly suitable for places characterized by a high presence of dust or smoke emissions , where improving air quality becomes essential to protect the health of personnel and maintain high production standards. Thanks to its robustness and the possibility of both manual and automatic water supply, the FRESH 150 purifier and cooler adapts flexibly to different operating contexts, always guaranteeing optimal performance even in conditions of intense use.
Among the strengths of the Kaltermann FRESH 150 is its ability to treat surfaces of up to 400 m² with a maximum air flow of 15,000 m³/h . Water consumption is maintained between 10 and 15 L/h , values that guarantee an excellent compromise between power and water efficiency. The noise level is contained at just 62 dB, allowing for a comfortable working environment without acoustic disturbances. Its dimensions, equal to 113 x 113 x 211 cm , and a weight of 230 kg, make it stable and easily integrated into industrial spaces. The low electrical consumption of 3.3 kW, combined with the plug & play water connection mode , helps to simplify daily use.

This portable air cooler with purifier can be used in these contexts:
