Ventilation generally

TYPES OF VENTILATION SYSTEMS

"BAUER" systems contribute to the perfect ventilation without drafts and thus better health of animals and acquisitions. We supply both vacuum systems, pressure, and equal-pressure.

In principle, in practice, ventilation systems, use the following:

TYPES OF EXHAUST VENTILATION

"Chimney" ventilation - for classical objects, especially for reconstruction. It is the ideal and cheapest system with inlet valves in the form of polyurethane or polypropylene flap window (to light stable) in the wall and exhaust chimneys with a fan in the roof.

"Transverse" - cross ventilation – for objects close to 12-15m (for fattening , extraordinary for sows or piglets, alt. separate systems of minimum ventilation). Cheap and functional system, but the inability to take full advantage of the cooling effect and regulate exactly the homogeneity of the air in a barn

Tunnel ventilation – in combination with other systems very effective system, especially in periods of high temperatures and areas with higher temperature. Suction of air happens from the side stalls and the exhaustion happens at the front of house through the fans. ventilations. In summer it is possible to add a cooling system in the other head of the stable.

"Combined" ventilation - based on a combination of the above systems - mostly "chimney" system with a tunnel system (in poultry barns), or tunnel with uder grid (pigs) system. We separate the minimum ventilation during cold seasons of the period of higher temperatures, the onset of intensive ventilation system.

Diffuse ventilation – air intake flow through the porous ceiling. Perfect for a stable system of pigs at low temperatures, ideal for 22-25 oC, at higher temperatures to be completed by cooling system. We ideally define zones, where 100 % air supply is from the zones where is necessary to ventilate limited.

"Corridor ventilation" (Duo System) – the perfect system for the pig barns, where the air supply is through the central corridor and from there to the various sections of wall gravity drain valves, and partly under the grates and partly to the chimney or wall (fan controlled 0-100%). The advantage is the possibility of passing already tempered, or cooled air and regulation of all air parameters.

"Under- grid” ventilation – exhaust air from beneath the grates. It's the perfect system for the pig barn, which combines the previous systems. Absolutely the best results are then combined under grid ("bottom") airing in the 30-40% performance with conventional vacuum system (for example tunnel).

"Natural" ventilation - is based on the use of servo-controlled curtains. The advantage is the possibility of "nature" ventilation during the power outage. Ideal for cattle sheds, stables for pigs and poultry for specific systems.

"Equal-pressure" ventilation

In the barn without the possibility of air inlet walls instalation, respectively.for wide stables has to be used Equal-pressure system (or systém with minimum negative pressure) with air inlet and outlet chimneys.The inlet can be positioned air mixing head.

Forced (over pressure) ventilation

This system is used in the stables where other systems cannot be installed. Air is supplied from given zone by ventilators and is collected by gravity. This is suitable for systems with central temperature or air cooling.
