Dual and Natural Ventilation


Combining mechanical and natural ventilations systems can:

  • Create the best conditions for sensitive livestock
  • Save you energy and money

Dual Ventilation

A dual ventilation system turns on and off as needed, requiring power as little as 20% of the time.

The right system can monitor and turn on power inlets and fans, working in harmony with your sidewall curtains, panels, ridge outlets and chimneys – and helping cut your energy costs by up to 80%.

Natural Ventilation

No mechanical ventilation present. All ventilation provided by chimneys and sidewall openings (with curtains or panels).


We can also help with water heating and lighting – other big energy users on your farm.

Save money, energy and our environment: that’s just good business.
