Kongskilde offers a wide range of high-capacity low-pressure fans for drying and ventilation of grain, rape seed, peas, grass seed, hay, beet, onions and potatoes. The air flow rate of the fan varies little with changes in the air pressure resistance, caused by different types of crops in silos, driers or on-floor stores. The fan is therefore also ideally suited for small-seed crops, having a higher resistance to the air flow, e.g. rape seed, clover, mustard. Owing to the very low temperature rise the fan is also suitable for ventilating and cooling of crops. In industrial installations the HVL fan may be used for exhaust and ventilation purposes.
The HVL blowers are an efficient air supply source to be used for ventilating steel silos independently of the air distribution system built into the silo bottom.
