Correct control of air direction, volume, and velocity

The LPV system is a classic negative pressure system used for the ventilation of poultry production facilities. The system is intended for temperate regions of the world and can be adapted to most livestock houses.

In an LPV system, the wall, ceiling, or roof inlets supply fresh air. During cold periods, fresh air is mixed with the housing air before reaching the area occupied by the birds.

During warm periods, the air enters the same way but is sucked into the livestock house at a higher speed. It results in air circulation around the birds, and they are cooled without perceiving the increased air circulation as a draught.

The system automatically adapts ventilation based on the outside temperature, production type, and age of the animals. 

The exhaust units are adjusted according to the Dynamic MultiStep principle, which substantially reduces power consumption.
