Air treatment system Green Vent

Dehumidification of greenhouses is important to optimize results. ITB therefore has developed the Green Vent air handling units. With this system, that has been developed according to the principles of The New Cultivation, air is dehumidified around the crops. Subsequently, the intake air is heated by the air coming out of the greenhouse. This can be done both by heat recovery through tubes, without the air being mixed, or by recirculating part of the air. Advantages Green Vent Dehumidification around the plant reduces the risk of mold-forming. Lower humidity in the greenhouse also reduces condensation around the plant. Better growth results are achieved and the quality of the crops increases. Energy is saved by using the warm exhaust air to warm up the intake air. Savings in energy costs can go upto 25%. Green Vent Unit The Green Vent Air Handling Unit is manufactured completely from plastic and stainless steel. The housing is produced from Uv-resistant polypropylene material according to the ‘hollow chamber principal’. The housing is assembled completely airtight by extrusion welding. The packages of tubes inside the system are produced completely from ABS and PVC. Because the system is produced completely from plastic, a long lifespan is guaranteed. The maximum capacity of these air handling units is 10.000 m3/h. Operation For greenhouses four types of air handling units have been developed, according to the different needs in a greenhouse. The recirculation unit has been developed in such a way that the air inside the greenhouse is extracted and (partially) recirculated.
