Mobile air cooler for workshops, industry, production, and large workspaces up to approx. 330 m²
The Master BC 221 Evaporative Cooler is a high-performance mobile air cooler for the targeted cooling of workshops, factories, halls, commercial spaces, and other large workspaces. With an airflow of up to 22,000 m³/h, it offers an energy-efficient alternative to conventional air conditioning systems and ensures more pleasant temperatures directly at the workstation.
Unlike a classic air conditioning unit, the Master BC 221 requires neither refrigerant nor complex installation. Cooling occurs naturally through the evaporation of water. This makes the device particularly suitable for areas where flexible and cost-effective cooling is required.
An evaporative cooler utilizes the natural effect of water evaporation. Warm ambient air is passed through damp cooling pads. Part of the water evaporates, extracting heat from the air. The cooled air is then blown directly into the room.
The heart of the evaporative cooling system is the cooling pad. Water is distributed onto the cooling pad and partially evaporated by the airflow passing through it. Evaporation requires heat from the air, which causes the temperature of the airflow to drop.
The evaporative cooling pads used consist of specially structured cellulose panels. Due to their large surface area, they can absorb water and enable efficient evaporation. The material is treated accordingly to support 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. Therefore, the cooling effect is particularly pronounced in hot and dry conditions.
The Master BC 221 can also be used in environments with higher humidity. However, the potential cooling capacity decreases as relative humidity increases. For optimal results, there should therefore be sufficient fresh air supply or ventilation.
Operation causes the humidity in the cooled area to rise slightly. According to the specified operating conditions, the relative humidity can increase by approximately 2 to 5% depending on the temperature and environment. In well-ventilated workspaces, this increase is usually minor.
The mobile air cooler is particularly suitable for large rooms and workspaces where a classic air conditioning system is not economically or technically feasible. Due to its high air throughput, the Master BC 221 can move large quantities of cooled air.

The Master BC 221 is a mobile evaporative cooler for large workspaces. With an airflow of up to 22,000 m³/h, it is particularly suitable for industry, workshops, warehouses, commercial spaces, and other large areas.
The Master BC 221 directs warm air over a water-moistened cooling pad. As the water evaporates, heat is extracted from the air. The resulting cooled air is then blown into the room.
According to technical specifications, the Master BC 221 is designed for areas up to approx. 330 m². However, the actually achievable cooling effect depends heavily on room height, outdoor temperature, humidity, air exchange, and local conditions.
No. The Master BC 221 operates on the principle of evaporative cooling and requires neither refrigerant nor a compressor.
The device has an integrated 120-liter water tank. Alternatively, a direct ½-inch water connection is possible.
The specified water consumption is approximately 12 to 18 liters per hour, depending on operating conditions.
Yes. The evaporative cooler can be operated even in higher humidity. However, the efficiency of the evaporative cooling decreases as the relative humidity increases. The device works most effectively in hot and dry conditions.
Yes. The device is equipped with large wheels and brakes, allowing it to be easily moved to the desired location and securely positioned there.
The Master BC 221 is a practical solution for the mobile cooling of workshops, production areas, warehouses, commercial spaces, and other large workspaces. With 22,000 m³/h airflow, a 120-liter water tank, and a low energy requirement of 800 W, the mobile evaporative cooler offers a powerful and flexible cooling option.
