Mobile air cooler for workshops, industry, agriculture, events, and areas up to approx. 250 m²
The Master BC 121 evaporative cooler is a powerful and mobile air cooler for targeted cooling in workshops, industrial and production areas, agriculture, patios, marquees, and other large or open spaces. With an air capacity of up to 12,000 m³/h, it offers a flexible and energy-efficient alternative to conventional air conditioning systems.
The Master BC 121 uses the natural principle of evaporative cooling. Water is passed over special cooling pads, and the warm air flowing through is cooled by the evaporation of the water. No complex installation is required, allowing the unit to be used quickly and flexibly at the desired location.
An evaporative cooler requires neither a compressor nor traditional refrigerants for cooling. Instead, the natural evaporation of water is used to extract heat from the warm air.
The heart of the Master BC 121 evaporative cooler is the cooling pad. Water is distributed over the cooling pad and absorbed by its structure. The warm ambient air is then guided through the moist pad.
As the water evaporates, heat is extracted from the air. This lowers the temperature of the airflow. The cooled air is then blown directly into the room or work area.
The evaporative cooling pads are made of corrugated cellulose sheets that are glued together. The structured surface provides a large evaporation area. The material is treated to ensure a long service life and reliable operation.
The performance of an evaporative cooler depends significantly on the temperature and relative humidity. Warm air can hold more water vapor than cold air. This is why evaporative cooling is particularly effective in hot and dry conditions.
The Master BC 121 can also be used when humidity is higher. However, the potential cooling performance decreases as relative humidity increases. Therefore, sufficient fresh air supply or ventilation is recommended for the most effective cooling possible.
Evaporation adds moisture to the cooled air. Depending on the ambient temperature and humidity, the relative humidity in the area of the airflow may increase by about 2 to 5%. In well-ventilated areas, this increase is usually minor.
Thanks to its mobile design and high air output, the Master BC 121 is suitable for numerous professional applications. Evaporative cooling is particularly practical where large volumes of air need to be moved and a classic air conditioning system cannot be used economically or without significant installation effort.

The Master BC 121 is a mobile evaporative cooler for large work areas. With an air capacity of up to 12,000 m³/h, it is suitable for workshops, industry, agriculture, events, and patios, among other places.
The BC 121 guides warm air over a cooling pad moistened with water. As the water evaporates, heat is extracted from the air. The resulting cooled air is then blown directly into the room or work area.
According to technical data, the Master BC 121 is designed for areas of up to approximately 250 m². The actual cooling effect depends on factors such as room height, outside temperature, humidity, air exchange, and heat load.
No. The Master BC 121 works with evaporative cooling and requires neither refrigerants nor a compressor.
The Master BC 121 has an integrated 80-liter water tank. Alternatively, the unit can be supplied with water via a direct ½-inch water connection.
The stated water consumption of the Master BC 121 is approximately 8 to 10 liters per hour, depending on operating conditions.
Yes. The Master BC 121 can also be operated in higher humidity. However, the efficiency of evaporative cooling decreases as relative humidity increases. The unit works most effectively in hot and dry conditions.
Yes. The mobile evaporative cooler has large wheels with brakes, making it easy to move to the desired location and position securely.
The specified power consumption is 500 W. This means the Master BC 121 is designed for comparatively energy-efficient operation.
The Master BC 121 is a flexible solution for the mobile cooling of workshops, industrial and production areas, agricultural operations, patios, and temporary events. With 12,000 m³/h air output, an 80-liter water tank, and a power consumption of only 500 W, the mobile air cooler combines high performance with a comparatively low energy demand.
