Outside 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 for the operations.UV-resistant, hail, reducing the pressure of top greenhouse
According to the different crops, rates of different sun-shading curtain is to meet the needs of different crops on the Sun.
Shading and cooling: through the closed curtains in the summer can effectively reflect part of the Sun, make greenhouse temperature reducing 4-6°

Inside Shading systems
Fog-drip-proof: when closed the system, it can be make two separating space greenhouse, can effectively prevent the formation of mist in the greenhouse and dripping fog.Energy-saving thermal insulation: in winter and at night, it can effectively prevent greenhouse radiation or heat exchange spills, thereby reducing energy consumption, reducing greenhouse operating cost.Saving on water: crops and soil water evaporation can be reduced effectively maintain air humidity, reducong irrigation.For increased the tempreture of greehouse, it can be used double visor system.

Cooling pad -exhaust fan system

The "cooling pad -exhaust fan"system of vertical ventilation is the most economical and effective cooling measures for greenhouse in summer.
The long time experiences can testifies that ,the "cooling pad -exhaust fan"system which is correctly installed can controls the temperature of greenhouse around 30 even in the most hot weather,and decrease the loss greenhouse around 30 even  in the most hot weather , and decrease the loss greenhouse around 30 even in the most hot weather ,and decrease the loss of production caused by hot weather to minimum.

Fully avoid the temperature balance of positive pressure combustion and combustion, flue gas overflows, local burn and other defects. Multi-level circulating heat exchange technology, heat around every corner, is a heat exchange more secure, more fully.Fresh air, temperature uniformity, can be controlled, forward-looking design of special double fan (energy + spare)
Our company using a new boiler furnace with high temperature resistant special cast steel pipe, seamless pipe and tube manufacturing from, this machine uses the secondary heating, high thermal efficiency, heating, air cleaner, semi-automatic temperature control, easy to install and so on.

Q1: What are the different types of glazing for Greenhouse?
A: The most common types of glazing are glass, polycarbonate, and polyethylene films. Glass is the longest lasting of the glazing, particularly if the glass is tempered. It is expensive relative to other two. It transmits light very well, but it does not diffuse light very well (may result in shadowing and plant burn if not carefully dealt with).
Polycarbonate (PC) generally comes in twinwall or even triplewall sheets in thicknesses from 4-16mm.
PC is easy to cut, and has a high degree of light transmittance and low thermal IR transmittance. Light is diffused with PC. PC lasts 15-20 years.
Polyethylene (PE) films are relatively inexpensive and are the easiest with which to work. Light is transmitted and diffused well. PE with infrared additives reduces heat loss at night. The lifespan of PE films is generally about 3-5 years. Other les commonly used glazings includes acrylic, fiberglass, and PVC.
Q2: What is shade cloth and do I need it on my greenhouse?
A: If your greenhouse locates in a humid area, misting or fogging may not be enough to cool your greenhouse in those hot, humid summer months. When all else fails you can create your own shade by putting the shade cloth on your greenhouse.
Shade cloth is usually made of loosely woven or knitted polyester or even aluminum foil. Densities or degrees of shade from appx. 5% to 95% are available for different plant needs.
Shade cloth can be installed exterior (on top of) the greenhouse with extra frame structure, or interior the greenhouse by hanging to the greenhouse pillars. Exterior shading is more expensive to build than that of interior, but exterior shading has better shading effect (cooling effect) than the interior shading.
Q3: What is the fan + evaporated pad cooling system and do I need it on my greenhouse?
A: Fan and pad systems consist of exhaust fans at one end of the greenhouse and a pump circulating water through and over a porous pad installed at the opposite end of the greenhouse.If all vents and doors are closed when the fans operate, air is pulled through the wetted pads and water evaporates. As each gallon of water is evaporated, 8,100 BTUs of heat energy is absorbed from the air by the water during the change from liquid to vapor. Removing energy from the air lowers the temperature of the air being introduced into the greenhouse.The air temperature reduces after passing through the pads. As the air moves across the house to the fans, it picks up heat from solar radiation, plants, and soil, and the temperature of air
increases gradually. The resulting temperature increases as air moves down the greenhouse & produces a temperature gradient across the length of the greenhouse, with the pad side being coolest and the fan side warmest.
Q4: I don’t have greenhouse experience before, how can I install the greenhouse that I buy form you?
A: The greenhouse we design are easy & quick to be installed with simple tools: hammer, drill, cutters, wrenches and etc. Detailed installation manual, with clear drawings and descriptions will be provided. If necessary, Kunyu would send technician(s) to your place and provide installation technical support.
Q5: Are there books that can help me get started with the greenhouse growing business?
A: We can send engineers to the job site for greenhouse installation

You just advise us your ideas on the greenhouse you like,
1) How large your greenhouse it is, Length x Width x Height, together with Span Width, Arch Width, Gutter Height;
2) The Covering Material(glass, film, PC or other material);
3) Your local temperature(Lowest, Highest), Wind Speed, Snow Load; Most of time, these factor will decide the essential systems the greenhouse may need;
4) Plants, Flower, Vegetable, Herb, Fruit or the plants will be going to in your greenhouse;
5) Where is your nearest port;
Then you will get our proposal with details to start your greenhouse building.
