Big Dutchman Cooling
Fresh air supply systems
– the right solution for every type of pig house!
The ideal cooling system for poultry houses in regions with hot and dry summers.
Evaporative cooling system with plastic pads
RainMaker is a cooling system which is mainly used in regions with hot and dry summers. It is based on the evaporation
Open system means water supply is always visible and allows no closed spaces for rodents to nest
Bottom trough acts as reservoir
Top deflector ensures water is evenly distributed on the whole pad
Easy installation and pads easily removed for maintenance
Water pumped with swimming pool pump
RainMaker features an innovative frame system with top profile and pad retainer
Top profile with perforated pipe and deflector for an even distribution of water along the pads
Practical snap-retainers allow for a simple and quick replacement of the pads
RainMaker can be used with conventional cellulose (paper) pads or the new plastic cooling pads.
Cellulose pads are made of a special cellulose material that provides a large surface area for high cooling capacity. Chemical impregnation protects the pads from the influence of weather
Coolbox decentralized cooling system made of high-quality plastic
Big Dutchman's Coolbox is an innovative cooling system, which is perfectly suited for pig houses with a central corridor. Moreover, in the case of poor water quality Coolbox is a better alternative compared to conventional cellulose pad cooling systems. Coolbox consists of a high-quality plastic pad and a frame made of glass fibre reinforced plastic (GRP). Coolbox is available in different sizes with different air capacities: 5 000 m3/h, 10 000 m3/h and 20 000 m3/h.
Mode of operation
The plastic material of Coolbox is watered from above. When hot outside air is sucked into the house through Coolbox, it comes into contact with the large, wet surface area which absorbs humidity. This has a very good cooling effect, lowering the in-house temperature. The system is controlled by means of a climate computer.
CombiCool effective high-pressure fogging system
CombiCool is a specially designed high-pressure fogging system for cooling, humidifying and wetting the pigs, especially in compartmentalised houses. The special SST nozzles are characterized by very low passage rates but an extremely high passage speed. This creates a very fine aerosol fog that is distributed evenly all over the compartment and is immediately absorbed by the hot air and so secures a comfortable temperature. Furthermore, CombiCool can be used for humidifying the in-house air throughout the whole year providing optimum humidity conditions.
Mode of operation
If the temperature rises above the preset level, the climate computer MC 235 activates the cooling system. The pump switches on and the main duct is loaded with a pressure of approximately 60 bar. A high-pressure valve which is installed over every compartment opens and a fine aerosol fog is sprayed into the space through the nozzles. The multi-step filter unit which is installed in front of the pump prevents foreign matter from blocking the nozzles.
