In winter months, greenhouse heating adds a great deal of cost to spring plant production. Typically, growers endure swings in climate as temperature and humidity rise until it is necessary to vent, bringing in cold air and releasing humid air. This is a typical “dehumidification” method in most greenhouses. Instead, using condensing dehumidifiers to lower humidity can reduce heating energy costs and prevent the climate fluctuations that effect plant health.
During a typical winter venting cycle, temperature and humidity rise to a point where venting occurs to purge the excess to maintain proper transpiration. The resulting cold air that is brought into the greenhouse can cause a shock to plants, increase disease pressure and cost extra money to heat this air back to preferred temperatures. Rising energy prices make this situation even worse.
Greenhouse dehumidifiers offer a better alternative to venting to release humidity. By removing moisture from the air via condensation and collection, we can optimize humidity without the major swings caused by venting. Temperatures can be kept more stable as well, preventing shock to the crop and excess heating costs. Dehumidifiers use much less energy to condense the moisture than reheating the air requires. Dramm VIFRA units are among the most efficient dehumidifiers available, reducing energy costs even more.
Combining proper air movement with Dramm’s decentralized dehumidifiers provides a very even climate throughout the greenhouse. Dramm can engineer a solution to homogenize the climate in your facility. Call us or click here to save energy and grow a better crop.
