DACS A/S offers CoronaD inlet fan. The CoronaD mixes fresh incoming air with warm room air and distributes the mixed, pre-heated air in the house. During the growth period, and depending on outside weather conditions, the mixing percentage of incoming air/warm room air changes automatically to maintain the optimum temperature on the ventilating air, the company says.
