ITB supplies climate components and energy-saving systems for horticultural greenhouses. With the GreenVent system from ITB, optimum air quality is achieved in the greenhouse. Moist air is extracted at the top of the greenhouse and conducted through a transparent channel to the heat exchanger. The incoming air is heated by the heat exchanger, without air mixing taking place. The system achieves high returns, which means that energy consumption can be up to 25% lower.
Dehumidification of greenhouses is important to optimize results. ITB therefore has developed the Green Vent air handling units. With this system, 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. 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%. 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. The airhandling unit is installed according to the plug and play principle. The system is placed at a solidified foundation and the channels and tubes are connected. Electricity and the computer are connected and the system is ready for use. The Green Vent air handling units can be controlled with equipment of almost all suppliers.
