Fans
Fan Accessories and Options by Solar Innovations, Inc.
Circulation fans are one of the most important accessories for a greenhouse. A circulation fan has several different functions all of which help plants. The main goal of a circulating fan is to create an even flow of air throughout the greenhouse, but there are many other benefits as well. 1. Removes air stratification. When air within a greenhouse stratifies, it becomes stagnant; air moving in one direction does not promote healthy growth. A circulation fan operates in the same manner it sounds, the fan circulates the air in the greenhouse. 2. Helps to control air temperature. As air moves within the greenhouse, the temperature adjusts itself. “Temperature spots” can not develop when the air remains moving. The temperature of the air and room will balance throughout the greenhouse, which creates a healthy growing environment. 3. Promotes air quality. The moving air cuts down on the ability of fungus to grow. Stagnant promotes the growth of fungus and disease. Freshly circulated air cuts down on disease outbreaks within the greenhouse environment. 4. Dries the leaves of the plants. Flowers such as orchids will suffer if water pools their leaves; a circulation fan is a necessity in an orchid greenhouse, as it will dry their delegate leaves. As the air circulates, carbon dioxide does as well; this promotes new growth in the greenhouse. Solar Innovations, Inc. offers several options when it comes to circulation fans. A Solar Innovations, Inc. representative can help you to determine the correct size and quantity of fans your greenhouse requires. All circulation fans are compatible with an optional manual speed control that adjusts the flow of air from 20% to 100%. The fan's controls are housed in a water-resistant electrical enclosure with approved connectors to withstand the high moisture greenhouse environment. Circulation fans feature a solid mount for attaching the fan to the greenhouse. This mount allows the fan to circulate without becoming entangled in chains . For an additional cost, Solar Innovations, Inc. offers one of the most reliable automatic single staged thermostats on the market. It features a wide temperature range and a narrow operating differential. The automatic thermostat is enclosed in a code-approved, moisture-resistant housing. These low maintenance circulation fans will provide the needed air flow within the greenhouse without increasing the overall structural maintenance. |

Circulation Fan Placement
Most vendors recommend a set of circulation fans be placed facing one another on opposite ends of the greenhouse. If a structure is over 60 feet long, it is recommended that circulation fans are installed in the same pattern throughout for adequate circulation, the greenhouse should be divided and an additional set of circulation fans should be installed.

| Hooded Cooling Fans are installed near the ridge of a glazed structure. This placement allows the fans to remove the hottest air at the ridge first and then continue to cool the remaining space. The unit is operated by a manual control or automatic thermostat. Hooded fans are available in standard Bronze, White, and Sandstone finishes, and include a wall mounted thermostat. (Typically used in sunroom applications.) |  |

Intake Louvers and Exhaust Fans work hand-in-hand. Often times called shutter fans, these accessories help to promote a healthy greenhouse atmosphere. These units have two main functions: to cool a greenhouse and to exchange air.
The intake louver is placed in the lower half of a greenhouse wall; the lover opens to let fresh air into the greenhouse. Air can also come into the greenhouse by way of opened windows. The incoming air is used to cool the greenhouse temperature and to promote the circulation of fresh, clean air.
Heat naturally rises, and the air eventually stagnates at the greenhouse's ridge. This is when exhaust fans come into play. After the greenhouse reaches a certain temperature, the exhaust fan pulls hot air out of the greenhouse and circulates fresh air back into the environment. This cycle is continued as deemed necessary to maintain the balance of temperature and air flow within the greenhouse.
Both the intake louver and the exhaust fans engage when the greenhouse reaches a predetermined temperature. Precipitation sensors prevent the units from opening when rain or snow is falling. The greenhouse typically utilizes these accessories in the summer when the temperature is elevated within the greenhouse. Cooling the greenhouse interior to a minimum of the outside temperature is achievable with an intake and exhaust fan. Further cooling will require supplemental cooling devices such as an evaporative cooler.
Although summer is the primary season for the use for these items, there are times during the winter when the greenhouse may overheat from direct sunlight penetration. During those times, it is useful to have an intake louver and exhaust fan.
Please note: The units themselves are not insulated and it is a good idea to insulate against harsh winters with foam or a panel for protection.
It is important to note that if a greenhouse is insulated, an exhaust fan and intake louver are not often required. Insulated glass choices and the increase in glass technology will control the temperature and air flow, with additions of circulating fans. If the greenhouse is single pane, then an exhaust fan is a very good piece to consider incorporating into your greenhouse.
