Evaporative cooler for workshops, warehouses, and industry
The Master BC 341 air cooler is particularly suitable for large work areas where a classic air conditioning system is not economical or difficult to implement due to spatial conditions.
With its high air output, the mobile evaporative cooler can move large volumes of air and provide noticeable cooling in workshops, warehouses, assembly areas, and production facilities. Since no exhaust air needs to be vented outside, its use is exceptionally flexible.
Ideal for large and well-ventilated areas:
Evaporative coolers are particularly suitable for halls, workshops, and other areas where warm air can be continuously exhausted and fresh air supplied.
How does an evaporative cooler work?
The principle of the Master BC 341 is based on the natural evaporation of water. Water is distributed via special cooling filter pads. Warm ambient air is then guided through these damp pads.
During evaporation, the water absorbs heat from the air. As a result, the air flowing through the cooling pads is cooled and then blown into the work area with high airflow.
The evaporative pads are made of specially designed, grooved cellulose plates. The large surface area allows for efficient water evaporation. The material is designed for a long service life and easy maintenance.
Evaporative cooling and humidity
The effectiveness of an evaporative cooler depends significantly on the temperature and relative humidity. The warmer and drier the ambient air, the more water can evaporate and the more strongly the air can be cooled by this process.
For this reason, evaporative cooling works particularly effectively in hot and dry conditions. At the same time, the humidity can increase due to water evaporation. In well-ventilated areas, the additional moisture is continuously removed with the air.
Especially effective in hot weather:
The higher the temperature and the lower the relative humidity, the more favorable the conditions for evaporative cooling. For closed rooms with very high humidity, other cooling systems may be more suitable.
Evaporative cooler as an alternative to air conditioning
A classic air conditioning system works with a refrigerant circuit and, depending on the model, requires appropriate installation. For large, open, or well-ventilated work areas, such a solution is not always optimal.
The Master BC 341 evaporative cooler, by contrast, uses water for cooling. No classic refrigerants are needed, and no warm exhaust air has to be vented outside via a hose. This allows the unit to be used with great flexibility in large work areas.
- No complex installation required
- No exhaust hoses necessary
- No conventional refrigerant required
- Low electrical power consumption
- High airflow of up to 30,000 m³/h
- Mobile cooling for large work areas
UV lamp and water treatment
The Master BC 341 has an integrated UV lamp for treating the water used in the device. UV technology can help reduce certain microorganisms in the water circuit.
The UV lamp thus provides an additional water treatment function. However, it does not replace the regular cleaning and maintenance of the water tank and water-conducting components.
Important:
For hygienic operation, the water tank, cooling filters, and water-conducting components should be checked and cleaned regularly according to the manufacturer's instructions.
Low energy consumption and low operating costs
With a power consumption of 1050 watts, the Master BC 341 requires comparatively little electrical energy for its high airflow. Cooling occurs via the evaporation of water rather than a classic compressor cooling circuit.
This makes evaporative cooling an interesting alternative to conventional cooling systems, especially for large and well-ventilated work areas. Actual operating costs depend on factors such as operating time, water consumption, temperature, and humidity.
