As farming has developed over the years shelters have become an important method to protect and raise animals in a controlled environment. In the attempt to shield out exterior climate influences, interior conditions that resemble ideal living conditions may have been neglected. Ensuring proper air exchange via Natural, Powered, Tunnel or Hybrid ventilation becomes a vital part in attaining maximum productivity.
Regardless of the system or the type of production that must be ventilated the Ventec team possesses the experience, and the production facilities required to meet projects on a worldwide basis. Let us prove our mettle and send your projects for our evaluation and recommendations.
Natural Ventilation (G3 Polymat, Tela simple, Tela Inflated, Isopan, Clearpan, Chimneys, Linear roof vents)
Natural ventilation for the agricultural industry is an economical and environment friendly method of providing fresh air to livestock. Typically, buildings will have insulated cathedral ceilings or at least the highest possible ceiling to allow for the use of air buoyancy to generate the natural ventilation effect. The main advantage of the G3 membrane curtain is that when it is inflated there is almost no infiltration of outside air even on windy days. The G3 system ensures an even temperature gradient within the building regardless of the outside environment. Wind, rain or snow have little or no influence on the performance of the polybag.
Mechanical Ventilation (Exhaust Fans, Air inlets, Max-Air Series fans)
In some cases, there are buildings, structures or natural barriers that make natural ventilation of buildings rather difficult. Also for smaller animals or processes that require a tighter temperature and ventilation rate control mechanical ventilation is an acceptable alternative. Using the appropriate extraction fans to create a lower pressure environment within the building and strategically placed air inlets controlled by a central automation system the minimum air requirements as well as the hot season cooling needs are met.
Tunnel Ventilation (Isopan Rigid Panel, Max-Air Series Fans)
This type of ventilation is considered a version of mechanical ventilation but is most often used as a summer cooling method. By using the smallest possible cross sectional area of the building the low pressure created by the exhaust fans creates a wind speed that effectively cools the animals within the shelter. Air speeds must be sufficient to ensure that the latent heat from the animals is removed quickly enough and exhausted from the building prior to warming the surrounding air excessively. Too much airspeed however can create an additional stress on the animals.
Hybrid Ventilation (Cyclone Plus or mix ventilation concept)
This type of ventilation occurs when many ventilation concepts are utilised together within a common building. Quite often more elaborate climate computers and algorithms are required.
