Proofed technology for a better climate
For those who would like to support naturally ventilated housing with mechanical ventilation, we have developed controllers for fans, air intake valves and curtains. We use them in livestock buildings with cattle, turkeys, ducks, fur animals and numerous other situations. In this way you have sufficient fresh air and oxygen and can prevent problems with draught, cold air fall and respiratory problems.

NVR-1/PThe NVR-1 ventilation controller is extremely suitable to control a ventilation valve or curtain in housing with natural ventilation. Depending on the temperature measured and the delay time set the intake is opened or closed. If there is a sudden temperature drop of more than 2 degrees (thunderstorm), the intake is closed extra quickly. The NVR-1P also has the facility to control the heating.Read more |

KKC climate computerThe KKC climate computer controls the climate in naturally ventilated livestock buildings. To do this the controller controls the intake valves in 4 groups independently of one another. In combination with the weather station the KKC switches the ventilation valves on the basis of the effect of the wind. You can prevent rain coming in by means of the optical rain sensor. As extra functionality the KKC-1 has controlled 0-10V heating and a counter input.Read more |
