Matched Equipment of the Greenhouse
(1) Ventilation System
The ventilation systems in our company consist of Roof Ventilation
Systems and Side Ventilation Systems according to the difference of
the installation position. The Roof Ventilation Systems include the
Roof Track-Cross Ventilation System and Roof Row-Rack Ventilation
System. The Side Ventilation System refers to the side Cooling-Pad
Ventilation System. Moreover, we also supply the Roof or Side
Plastic-Film Reeling Ventilation System (Manual or Electric).
Main Accessories: plastic-film reeling motor (or manual machine),
plastic-film shaft, plastic-film-fastening profile, telescopic
arms, etc.
(2) Shading System
The Shading system can keep out redundant sunshine, preventing the
plants from being burned in the greenhouse. And it can regulate the
heat or reduce the cost of the operations.
The outside Shading System is fixed above the frame of the
greenhouse, supported by the uprights and beams. The outside
shading net is made of black and round-wire materials and fastened
by black polyester strings.
(3) Cooling System
Our company is specialized in products of cooling pads and fans,
usually used cooperatively. The cooling pads are installed on one
side of the greenhouse, and the exhaust fans, the other. (The
air-circulating fans are installed in the greenhouse.) The exhaust
fans eject the air from the greenhouse (The air-circulating fans
promote the circulation of the air in the greenhouse), and negative
pressure forms in the greenhouse. The air enters the greenhouse
through the cooling pads, resulting in the effects of cooling,
moistening, and air-dedusting.
(4) Heating System
The Heating System of a Greenhouse refers to a set of suitable
heating facilities chosen to meet the heating demands, consisting
of a heating source, heat-radiating facilities, and
heat-transmitting facilities. The main accessories include a
furnace, transmission pipeline, circulating water, radiator, and
sorts of controlling or regulating valves, etc.
