1 Framwork material
Hot galvanized steel.This kind of steel has good anticorrosion and antirust effects, which can help extend the service life of the greenhouse.
the Venlo Greenhouse is supported by the square tubes, connected by truss, gutter, and other related connectors. They are made by galvanized steel. The Glass and PC-sheet Venlo Greenhouses are different from each other mainly at the roof and the covering materials. All of the frame materials are metal, no plastics and no welding point.
2 Venlo Greenhouse Window Ventilation System
The venlo greenhouse window ventilation system can be installed on the roof or side wall, controlled by the gear motor and rack-pinion structure to make the window open or close. On the roof, it can be Driving-rod Ventilation System or Row-rack Ventilation System. On the side wall, it is Row-rack Ventilation. The rack can be straight or curved.
3 Venlo Greenhouse Wet curtain and Fan Cooling System
about the venlo greenhouse cooling system, our company is specialized at the products of Cooling Pads and Fans, usually used cooperatively. The Cooling Pad is installed on one side wall of the greenhouse, the Exhaust Fan the opposite. ( The Air Circulation Fan is installed under the roof of greenhouse.) The Exhaust Fan ejects the air from the inside of the greenhouse, (and the Air Circulation Fan promotes the circulation of the air in the greenhouse), negative pressure formed in the greenhouse. The cooling water flows through the Cooling Pad with the help of the water-recycling facilities. The air enters the greenhouse through the Cooling Pad, resulting in the effects of cooling, moistening and air-circulating. The temperature can be cooled down about 8-15 degrees defined by the temperature of the cooling water and the sizes of cooling pad and exhaust fan as well as the size of the greenhouse construction area.
4 Venlo Greenhouse Shading System
The shading system, outside or inside, installed on the roof or under the roof of the greenhouse, can keep out the redundant sunshine, preventing the plants from being burned in the greenhouse. The outside shading system can also function to prevent the hailstones and the inside shading system can also play a role of keeping warm. The outside shading system is fixed above the greenhouse frame, supported by galvanized steel square tubes and beams. Outside shading net is made by the black and round-wire materials. The inside shading system is installed under the greenhouse roof, fastened on the truss and with the greenhouse frame. Inside shading net is made by the white and aluminim-alloy materials, fastened by white polyester strings.
