Automated Retractable A Frame Greenhouse
Automated Retractable A Frame Greenhouse
The house is designed for extreme conditions.Mostly for colder climates with snow load and excessive winds.Typically narrow spanned. Same roof and perimeter wall covers are used. (Double coated fabric should be used on the roof).Up to 3 different independent retractable roof can be applied. For ex: Main roof, Curtain, Insect net.Same configuration of perimeter walls can be applied.Snow and wind resistance can be increased with extra cost.
Frame structure
High-grade galvanized steel that can withstand wind and snow.
All steel, and hardware for body of frame.
Maximize land use, maximum volume per square meter
1. Galvanized steel skeleton to get high disaster resistance.s
2.Resists corrosion.
3. Stable structure and high quality.
4. Factory made, the lowest price.
5.Lifespan over 15 years.
Specifications & Parameters
| Enhanced Cooling |
With all the trapped heat and energy in greenhouses, retractable roof greenhouses enhance the cooling effect. A ventilation system is not big enough to exhaust heat as quickly as greenhouses take them in. Retractable roof greenhouses take trapped heat out of the equation. |
| Heat Retention |
When paired with an energy curtain system, retractable roof greenhouses have the ability to trap heat while the roof is closed, providing protection from freezing wind, snow and hail. There are three types of curtain systems that will help keep your structure at optimal growing temperatures:
|
| Flat Roof | The retractable flat roof greenhouses are an affordable way to protect rain tolerant crops from excessive heat, cold, and wind. There is a wide variety of water porous roof coverings and structural designs that allow for the optimal balance between crop requirements, environmental conditions, and the level of investment. This style is best suited for tropical/semi-tropical regions with arid dry conditions. |
| A-frame | Retractable Roof Greenhouses are ideal for areas where climate is unpredictable. Help provide year-round protection for your investment by calling one of our greenhouse experts today at +86 188 8427 8612 |

12ft, 14ft, 16ft, 18ft or 3.65m, 4.3m, 4.87m, 5.5m
Roof closing time:2.5 minutes
- Designs available for wind speeds up to 210km/ hr and 170kg/ sq m snowloads
Realized by the principle of water evaporation and cooling. When the air penetrates the water curtain, it exchanges heat with the water vapor on the surface to realize the humidification and cooling of the air.

Using the temperature difference or wind pressure inside and outside the greenhouse to realize air convection inside and outside the greenhouse, reducing the indoor temperature and humidity.
Side opening window system:Geared motor, rack and pinion, transmission shaft tube, push-pull rod, push-pull pulley, support rod, window frame top/roof windows system:A geared motor, a gear, a rack, a bearing housing, and a transmission mechanism connected with a transmission shaft tube.
The top and side windows are assembled with special aluminum alloy profiles and sealed with rubber strips.
