Greenhouse fans

For growers, it is important that crops in the greenhouse grow evenly. By circulating air using fans, a uniform greenhouse climate is created and the risk of plant diseases and moisture damage is limited. This simplifies business operations and increases production.

Greenhouse ventilation for optimal crop development

The importance of good circulation and ventilation in greenhouses is often underestimated. Nevertheless, it is an important yet complex issue that involves many factors. After all, how do you effectively create a uniform greenhouse climate while external influences are constantly changing?

Our years of practical experience and performing many smoke tests have proven that fans are an effective tool to achieve various important benefits in the greenhouse. For example, the reduction of humidity-related plant diseases and pests, or more uniform plant growth, which simplifies business operations and increases energy savings.s and increases energy savings.

Forced Ventilation in Greenhouses

In addition to circulation fans, forced ventilation in greenhouses is crucial for maintaining optimal growing conditions. Forced ventilation systems help control temperature, humidity, and air quality, ensuring that crops receive the best environment for growth. This method can be particularly effective in larger greenhouses or in regions with more extreme weather conditions.

Horizontal air circulation

Horizontal Air Circulation

Horizontal Circulation Fans mix the air above the plants at a high speed from fan to fan. This can be done according to the serial or parallel ventilation principle. As a side effect, due to the airspeed, the air between the plants is set in motion and big horizontal temperature differences are evened out. Our high-efficiency HAF (Horizontal Air Flow) fans ensure a consistent horizontal pattern, maintaining uniform temperatures inside the greenhouse. HAF fans are particularly effective in preventing the buildup of hot air, ensuring a more even distribution of cool air. Horizontal air flow HAF systems are integral in achieving this balance.

Vertical air circulation

Vertically mixing the air with the help of V-FloFans creates a constant airflow between the plants, which ensures an active microclimate. In addition, this fan mixes sun-heated air with cooler layers of air at the bottom of the crop, thus evening out vertical differences in temperature and humidity. V-FloFans are often used in greenhouses where the 'Next Generation Growing' principle is used for growing.

Natural Ventilation in Greenhouses

Natural ventilation in greenhouses, such as using roof vents and passive ventilation, can complement mechanical systems. By leveraging the natural movement of air and prevailing winds, growers can create a balanced environment that promotes uniform temperature and reduces the reliance on mechanical systems. This helps in introducing cool air and maintaining stable temperature conditions.

Reducing humidity with exhaust fans for greenhouses

To reduce humidity in a greenhouse, a mechanical ventilation system can be a fitting solution. With the help of Galvanized Box Fans, humid air is extracted from the greenhouse and dry air is pumped in through air inlets. The correct fan location and fan capacity are essential to ensure optimal air conditions and fresh air supply.

Greenhouse fans

Our Multifan horizontal fans are also called greenhouse fans. The design of these fans has been specifically developed for the greenhouse sector. With their high efficiency and ability to create a uniform temperature and fresh air flow, they are ideal for maintaining optimal air conditions and supporting the overall health of the plants. Using a combination of fan and vent systems ensures that temperature conditions inside the greenhouse are kept stable and conducive to plant growth. This mix of fan and vent solutions, including passive ventilation and forced ventilation, ensures that growers can maintain ideal temperatures inside the greenhouse.

Expansion with the Multifan V-FloFan to save heating costs

Intergrow Greenhouses has realized another expansion that will give the company 18,5 ha of greenhouses in Gaines, New York, USA. Part of this expansion was the installation of 94 Multifan V-FloFan equipment. 

“We have been expanding to produce local-for-local tomatoes”, explains co-owner Dirk Biemans. Intergrow first opened a greenhouse in Fillmore in 1998. The site continues to grow beefsteak tomatoes. In 2003, Intergrow started at a new location only at 10-hour striking distance from New York, New England. “We tell our customers we pick it today and you’ll have it tonight,” Biemans said.
