German turnkey stables producer Hölscher + Leuschner will present a novel type of air inlet for poultry and pig housing at the upcoming edition of EuroTier.
The ‘VRV Air’, designed to be fail-safe and maintenance-free, is supposed to work even in the case of a power shutdown. Key are three elements:
Adequate sizing of the inlets, so that sufficient natural ventilation of the building is ensured in the event of a power failure.
The regulating units for the ventilation elements in normal operation at the same time are also the ventilation units in emergency mode, so that a lack of functionality would be noticed immediately by the everyday use of these regulation untis. In normal operation a defective functionality does not cause any damage, but is directly communicated by a system error message. Any further maintenance is therfore not necessary.
Accurate control of the air inlet velocity to ensure constant climate in the compartment without the occurrence of drafts. This is particularly important because the air inlets have a total of large cross-sections and therefore exact positioning and precise control of the depression as indirect parameter for air inlet velocity are essential.
Hölscher + Leuschner can be found at EuroTier in Hall 11, stand F24.
