Exhaust Air Chimneys
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 cleaner.
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 been started one after another at 30 percent is their speed increased simultaneously to 100 percent when the ventilation demand requires this.
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 easily.
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 time.
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 stable.
