Circulation Fans For Greenhouses

Circulation Fans For Greenhouses

The movement of air in greenhouses is a key element to healthy plant growth and disease prevention.circulation fans for greenhouses Greenhouses without adequate air circulation can have hot and cold spots which affect the plants. Air circulation fans provide an even distribution of temperature, humidity and carbon dioxide which promotes strong, healthy crops. The movement of the air also reduces condensation and diseases caused by wet foliage.

Several different types of greenhouse fans are available.circulation fans for greenhouses Some, like the horizontal airflow (HAF) fan, are designed to operate against zero static pressure and force the greenhouse air through louvres to create circulation. The HAF is an excellent choice for large or commercial greenhouses as it operates very quietly and requires little maintenance. It is also available in a solar powered version to minimize electricity use. Other fans are designed to mix the air at ground level, such as a destratification fan. This removes stratified layers of warm air that gather at the ceiling and mixes them with cooler air at ground level. It also helps eliminate wet areas and increases the efficiency of heating systems.

Another type of fan is the evaporative cooling fan.circulation fans for greenhouses These are tied to a water reservoir which cools the air by evaporation. These are useful in greenhouses where humidity is a problem, such as orchids and flowers that require very low moisture levels.

All of the fans we offer come with a built-in controller to allow you to set the desired speed and to shut the fan off if necessary.circulation fans for greenhouses These controls are encased in an water resistant electrical enclosure and have approved connectors that can withstand the harsh greenhouse environment. They have an easy-to-read dial that allows you to adjust the fan to a maximum of 100% of its normal output or to shut it completely.

Circulation fans are a vital component of any greenhouse. They help to reduce heating costs by circulating the warm air so that it doesn’t settle in hot and cold spots, which can drive up energy bills. They also increase the air flow around the crop, preventing mildew and other plant diseases by eliminating the stagnant air that can lead to them. It also provides better oxygen utilization for the plants, something that is crucial for plant health and production.

For optimum results, the ventilation system should be sized to circulate the air volume in the greenhouse about 1 to 2 times per hour. If this is not possible, then you should consider installing additional fans or increasing the size of the existing ones. In addition, you will want to make sure that your greenhouse vents are properly adjusted before the winter heating season to ensure they close and seal tightly. Failure to do this can result in a great deal of heat loss through poorly closing vents. There are automatic openers for your greenhouse vents that can be installed to open and close them when needed.
