Model CL 600 - Versatile Exhaust Air Chimney
The versatile exhaust air chimney with a unique design. The CL 600 exhaust air chimney has an aerodynamic shape and ensures optimum ventilation conditions. The chimney is made of polypropylene, has a smooth, dirt-repelling surface and is insensitive to sunlight and frost. The chimney can easily be cleaned with a high-pressure ...

Model CL 920 The XL Version - Exhaust Air Chimney with High Air Performance
The air performance of the CL 920 is almost double that of the CL 600, which is why the CL 920 should be installed in barns with large exhaust air removal requirements. The suction head with integrated butterfly valve and the diffusor are made of polypropylene. The high-density polyurethane foam exhaust air duct consists of two half pipes, thus saving transport costs. This structure ensures good insulation and prevents condensation water. The chimney ...

Model CL 600 - Guide Vane Exhaust Air Chimney
The CL 600 guide vane is simply screwed tightly to the CL 600 exhaust air chimney right above the fan. The exhaust air jet is concentrated by deviating the radial and circular flow components. This leads to a significantly increased working range of the chimney. The guide vane can be retrofitted ...

Model BD - Exhaust Air Chimneys VC
BD exhaust air chimneys are available with several different diameters (520, 650, 730, 820, 920 and 1270 mm) and can therefore be adapted to any ventilation concept and spacing of roof trusses. The fans and exhaust air chimneys offered by Big Dutchman are exactly coordinated. An exhaust air chimney with aspirating mouth and diffusor leads to a 10 to 15 percent higher air performance. At the same time, the specific power consumption is reduced by 5 ...

Chimney Silencer for BD Exhaust Air Chimneys VC
Main advantages: The new chimney silencer is an innovation used to reduce noise emissions. The German Technical Inspection Association TÜV Nord measured a noise reduction of up to 12 dB(A) (for pipe diameters of 650, 730, 820 and 920 mm) in official tests. The total length of the silencer is 2.5 ...

Central Exhaust Air Removal
Reducing emissions from livestock housing facilities will become more and more important in the future. Especially for new barn buildings, licensing authorities often require that the point of exit of the exhaust air be installed at a height of no less than 10 m and that the exhaust air is extracted at one location (i.e. bundled). This makes the air jet produced by a bundled emission source more ...

MultiStep - Energy-Saving Exhaust Air
The energy-saving exhaust air principle using the CL 74 and CL 74V actuators. Main advantages: The exhaust air principle MultiStep® combines stepless control and group control. The principle’s advantage is a significant reduction in energy consumption while the same air performance can be maintained: Compared to traditional negative-pressure systems, annual savings of up to 50 percent are possible. Due to the steady, maximum exit speed ...

MultiStep - Dynamic Exhaust Air Principle
The enhanced version of the MultiStep exhaust air principle. Main advantages: The enhanced version of the well-proven MultiStep principle is called “Dynamic MultiStep”. This system works exclusively with the new ECblue fans that save even more energy. Instead of starting them at 100 percent speed, these fans begin working as early as at 30 percent (up to 50 percent depending on the required pressure resistance). Only after all fans have ...

ECblue - Exhaust Air Chimneys
The innovative fan with high potential for energy savings. ECblue fans not only save energy but are also extremely resistant to pressure and thus less susceptible to wind. This stability is very important when using minimum ventilation. This is because strong winds have extreme effects on the minimum ventilation concept, especially regarding the animal’s well-being and the heating ...
-
DynamicAir - Exhaust Air Chimneys
For precise recording of the volume flow of exhaust air chimneys. DynamicAir is a new principle invented to optimise the air exchange in livestock housing facilities. Especially with minimum ventilation, it is very important to know exactly how much air passes through the exhaust air chimney to be able to provide optimal climate conditions for the animals and to reduce the heating costs at the same ...
