For 25 years Sun-North has designed ventilation systems for swine facilities from northern Canada to Australia.
Sun-North offers 3 options in the ventilation of swine housing:
Natural Ventilation |
|
 |
Sun-North utilizes the natural forces of wind and temperature to ventilate swine facilities from 10 meter to 35 meters wide by virtually any length. Typically NO fans or forced inlets are used. Sun-North manufactures vertical moving sidewall panels/curtains and ridge outlets that are controlled electronically to provide a complete ventilation system. An all natural ventilation system offers numerous benefits from 85% savings in energy costs, reduced dust, noise and heating costs along with a much more pleasant work environment. |
Dual Ventilation |
|
Extreme climate conditions such as northern winters and southern summers may require power assist to maximize or minimize airflow to optimize animal comfort. Sun-North will incorporate power ceiling inlets, power chimney fans and/or power sidewall fans to engage before the natural ventilation sidewall panels and ridge system is implemented. Typically power assist would be designed for a maximum 20% of the needed ventilation. This allows the producer to utilize natural ventilation 80% of the time, saving on energy and having the advantage of sidewall openings during extreme heat and a ventilation system that remains operational in the event of power or generator failure which could cause severe death loss due to suffocation. | |

Tunnel or Cross Flow Ventilation |
|
 |
This system requires the side wall panel or curtains to close up completely during hot conditions. Typically the end wall of a building has static controlled doors with misting or water cooling panels that operate in sync with a bank of fans in the opposite end or sidewall of the building. This combination or evaporative cooling and a large volume of air movement through the building can lower the inside temperature by 5 to 10 degrees. |
Finishing |
|
A naturally ventilated finishing barn operates by opening up the sidewall from 1 m to 2 m and placing an Altra-Wall panel over this opening that then moves up and down manually or automatically on tracks. The incoming fresh air is heated as it moves over the animals and is drawn out through the chimneys which are baffled to control the flow of exhaust air. Summit Curtains or insulated curtains can be used in place of Altra-Wall panels. | |

Breeding & Gestation |
|
 |
Natural ventilation is the preferred choice of many breeding swine operator’s since it provides abundant natural light and is a much quieter working environment for animals and operators along with plenty of fresh air. The operator will decide on a total natural barn similar to a finishing barn but with windows in the sidewall panels or a dual ventilation system that incorporated power fans to assist during minimum ventilation situations. The system can be operated automatically by Sun-North’s Shepherd electronic controls with computer assist or manually. View More.... |
Farrowing & Nursing Barns |
|
 |
Scandinavian countries have made great strides in using natural ventilation in farrow and nursery facilities and it is their number one choice. The reasons they prefer natural ventilation are lots of natural light, plenty of fresh air and less aggression because of less noise. Sun-North sliding wall panels with windows allows the fresh air in which becomes heated and then exhausted through ridge chimneys. Dual ventilation using power fans for minimum ventilation is a good option. The system can be automatically operated by Sun-North’s Shepherd electronic controls with computer assist or manually.
