MANAGING THE COMPLETE BARN ENVIRONMENT FOR HIGH PERFORMANCE

Vic Tri-Star ventilation combines three ventilation
systems into one powerful system :

  • Natural ventilation
  • Tunnel ventilation
  • Super Cool High Pressure Misting

TRI-STAR IN WINTER

TRI-STAR IN WINTER

  • Supplies clean fresh air evenly throughout the structure.
  • Removes excess moisture. Eliminates wet ceilings.
  • Removes manure gases, pathogens and other contaminants.

TRI-STAR IN SUMMER

  • Significantly reduces heat stress.
  • Provides high levels of air exchange.

The bottom line with dairy ventilation is whether the cows are comfortable and their daily dry matter intake is sufficient for maximum milk production and reproduction. This is Tri-Star

INSULATED CHIMNEY

  • The insulated natural chimneys work like a fireplace, once the flue is warm it keeps pulling air out of the barn. Opening around the damper allows warm, moist air to escape along the sides and keeps the chimney flue warm.
  • The Expert Tri-Star has up to four chimney damper outputs for maximum design and expansion flexibility.

RELATIVE HUMIDITY PROBE

  • Expert Tri-Star enables up to 2 inside and 1 outside probe.
  • Using the Relative Humidity Probe ensures that the chimneys and panels are adjusted to maintain the desired moisture conditions. The minimum ventilation rate can be set precisely to the cows needs.

INSULATED PANEL

  • Expert Tri-Star operates up to 8 independent sidewall panels.
  • Panels start opening in very small increments. The increment increases as the panel continues to open.
  • De-icing cycle is activated when a panel has not moved for a selected period of time when the outside temperature is below the selected value.
  • All panels will go through the de-icing cycle at different times to avoid large amounts of cold air entering the building at one time.
  • Security setting based on actual barn temperatures rather than the set point temperature is insurance against freezing up the barn with too much airflow.

TEMPERATURE PROBE

  • The Expert Tri-Star enables up to two probes per panel plus one for outside temperature.

WIND COMPENSATION

  • If either the wind speed or wind direction are unfavorable for the current ventilation in the barn the Expert Tri-Star will reduce the panel opening to compensate for the wind. This prevents bedding loss from the stalls.

TUNNEL VENTILATION WITH TRI-STAR

When temperature rises, tunnel ventilation effectively reduces the actual temperature perceived by the cows. Heat stress creates huge challenges for dairy cows :

  • Lower feed intake
  • Milk production drop
  • Drop in milk fat level
  • Depressed immune systems
  • Decreased fertility - shorter heats, silent heats, lower conception rate

SUPER COOL HIGH PRESSURE MISTING

  • As temperature rises, humidity comes down and Super Cool increases the misting rate and the cooling effect.
  • If the humidity level rises over the selected RH limit, the Super Cool automatically reduces the misting rate. Super cool keeps modulating up and down as needed, providing the maximum cooling possible under the existing temperature and humidity conditions.

CIRCULATING FAN

  • Circulating fans do not provide the same level of effective cooling as tunnel but in conjunction with Super Cool High Pressure Misting it can be used as an alternative to tunnel where tunnel is not practical.
  • Expert Tri-Star enables up to four stages of circulating fans with possibility of 2 of these stages being variable.
  • Select the start and stop temperatures for each stage.
  • Expert Tri-Star will monitor the difference between all assigned temperature probes and if the difference is too high Expert Tri-Star will activate a circulating fan stage to reduce the difference.
