Functional specifications
Professional cooler Made in Italy
The Master BC 121S is an evaporative cooler designed for work environments and industrial applications. Made in Italy, it guarantees high efficiency with an air flow rate of up to 12,000 m³/h , sufficient to cool surfaces up to 250 m² . Its solid, corrosion-resistant plastic structure makes it suitable for harsh environments, while the wheels with brakes make it easy to move.
80 dm³ cooling panel for constant fresh air flow
Equipped with a large 80 dm³ cooling panel , the Master BC 121S ensures a constant flow of fresh air with a low energy consumption of 500 W. Despite its high performance, the noise level remains at 67 dB(A ), ensuring a comfortable working environment even during prolonged hours of use.


60 L tank and possibility of connection to the water mains
The Master BC 121S boasts a spacious 60 L tank that ensures long periods of use without the need for constant refilling. The cooler can be supplied with water via manual loading or connected directly to the water mains for automatic filling , thus simplifying daily operational management. The water level control is integrated to avoid waste or unexpected interruptions. Consumption varies from 8 to 10 L/h depending on the intensity of use.
Robust yet easy to handle cooler
Weighing just 50 kg , the Master cooler is constructed of corrosion-resistant plastic, designed to be used as a cooler in harsh work environments. Large, lockable wheels make it easy to move the device safely around workspaces, making it versatile and easy to position.

Control Panel
The Master BC 121S can be controlled via the practical control panel , which allows you to adjust the fan speed and activate the oscillation function . A special feature of this machine is the presence of a new integrated UV lamp that disinfects the water by eliminating germs and bacteria.


Cooler that improves air quality
Built-in UV lamp to disinfect water
The latest-generation UV lamp integrated into the Master BC 121 disinfects the water in the tank before it is released into the environment. It works by emitting ultraviolet rays (UV-C) that destroy bacteria, viruses, and microorganisms present in the water , preventing the proliferation of pathogens. This system improves the quality of the air emitted and ensures safer and more hygienic cooling, ideal for industrial environments where air quality is a priority. It does not require frequent maintenance.


Air filters included to retain dust and impurities
The air filters included in the Master BC 121S play a key role in improving the quality of cooled air. These filters trap dust, impurities, and particles present in the drawn air, preventing them from spreading into the room. They are easily removable , allowing for quick and regular cleaning, which maintains the device's efficiency over time. In addition to protecting the health of occupants, the filters also help keep the cooling panel clean , extending the device's life. Ideal for industrial or dusty environments, they offer a practical solution for healthier air and reliable operation.


How Evaporative Coolers Work
Warm air passes through the evaporative filter and, thanks to the cold water in the tank, is charged with humidity. The air then becomes cooler, purified, and released back into the room. The outgoing air is therefore humidified and cooler, and, upon contact with the skin, it induces a feeling of well-being. This effect is more pronounced in hot, dry environments.
