Ventilation is important
to optimize your pig production

LPV

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

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 it reaches the area occupied by the pigs.

LPV+

The LPV+ system is a classic negative pressure system used for ventilation of pig production facilities. The system is intended for hot climatic zones of the world.

In an LPV+ system, the ceiling inlets supply fresh air. During cold periods, fresh air is mixed with the housing air before it reaches the area occupied by the pigs. The air is taken in via a well-insulated attic space. It ensures that the air is not unnecessarily heated before it enters the livestock house.

Combi-Diffuse

Combi-Diffuse ventilation is a negative pressure system for pig production in the temperate parts of the world.

The Combi-Diffuse system consists of a ceiling made of special ceiling panels that have an open surface structure. The negative pressure causes the air to enter through the open structure. The ceiling panels reduce the air velocity, ensuring there are no draught discomforts for the animals during cold periods.

During warm periods, ceiling inlets provide extra ventilation.

Equal Pressure

The equal pressure system is a ventilation system used for pig production facilities. The system is intended for temperate regions of the world and can be adapted to most livestock buildings.

In an equal pressure system, roof inlets supply the fresh air, and the outlet is conducted through chimneys, both with active fans that create a neutral pressure.

Combi-Tunnel

Combi-Tunnel is a fully automatic all-weather system that provides the poultry the best possible productivity conditions when the outside temperature changes from very cold to very hot.

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

When the outside temperature is low, the system keeps the temperature and air humidity at an ideal level by removing excess humidity and heat generated inside the livestock house.

Tunnel

In a Tunnel ventilation system, the air intake is located in the sides or the house end at one end of the building. The air intake is lined with cooling pads. Different types of air intake are available, which you install in connection with pads or high-pressure cooling to cool down the incoming air.

At the opposite end of the tunnel opening, large gable fans create a cooling air current (chill effect) along the longitudinal direction of the livestock house. Depending on air humidity, it is possible to lower the temperature perceived by the animals substantially.

Air filtration

The ventilation system with air filtration is used for ventilation of pig production facilities. The system is intended for temperate regions of the world, and it can be adapted to most livestock buildings.

Positive pressure ventilation characterizes the solution. It ensures that the air enters the livestock house through filters and not via leaks in the building. It is a real risk in livestock houses with negative pressure ventilation, especially in connection with older livestock houses.
