The highest level of technical development, professionalism, as well as a clear organization of the production process guarantee our customers the timely delivery of materials that meet international standards for commercial greenhouse facilities, as well as installation at a high-quality level. We are pleased to offer to your attention the 5th generation Active Climate greenhouse of Venlo type and arched Gothic greenhouses with film and polycarbonate coating and a bay width of 9.6 m and 12.8 m. Designs of this type are widespread throughout the world and have certainly proved their worth by their reliability. During the construction, high-quality materials are used. All steel parts of the structure are galvanized, which extends the service life and protects the material from corrosion.
In the construction of the foundation, we use support structures of the Zeus type, which are installed on a reinforced concrete layer.
This design of greenhouses provides for ventilation windows. Their area is at least 25% of the total, which makes it possible to maintain the optimal intake of outdoor air to maintain optimal temperature conditions during intense solar radiation.One of the important parameters of greenhouses is their high light transmission. This effect is achieved due to the optimal placement of the heating system and the verified design parameters that impede the entry of light into the greenhouse. This makes it possible to provide plants with an optimal level of lighting.
For the effective functioning of the greenhouse complex, appropriately designed service rooms are essential. At the design stage, wishes regarding the internal movement system and the growing methods used are taken into account.
Service rooms include:
1. Boiler-house and mixing room, according to verified design parameters of heating and irrigation.
2. Sorting room designed according to the area depending on the set of equipment (sorting units, lines, manual sorting)3. Warehouses
When implementing an integrated project, the heating system is essential. It is the nervous system of the modern greenhouse economy which should operate reliably. The company has a wide range of materials and equipment.
Modern gas and solid fuel boilers
Suspended heating systems
Heat accumulation systems
Carbon dioxide meters
Pumps, valves and other equipment
The entire central heating system is designed according to the Tigelman principle, which means that equal resistance will exist throughout the circuit and an optimal heat distribution in the system will be achieved.
Boiler equipment can be different, both in type of fuel, and in set tasks that must be solved during operation. The boiler will be connected to the central manifold, which will be located in the boiler-house. We provide the whole set of materials necessary for a complete installation in the boiler-house. Connection of the manifold with boilers will be made with the use of supply and return line, with the installation of automatic deaerators
To adjust the pressure change when the volume of water in the system changes, a pressure maintenance tank will be installed in the boiler-house.
Pipe-rail heating system
A pipe-rail heating system will be installed in the greenhouse. It is the lower heating circuit and at the same time serves as transport lines for moving trolleys between the rows. This system is installed at a height of 11 cm from the floor with the help of special securing stands. Typically, pipes with a diameter of 51 to 60 mm are used for this system, which are connected to distribution lines along the end cover.
The curtaining system is designed to reduce the air temperature in the greenhouse during periods with excessive solar radiation - shading of plants, as well as heat loss in the cold season, creating a more uniform and favorable temperature regime for plants throughout the entire area of the greenhouse. The design of the curtaining system allows the polymer screen to be moved simultaneously in all bays. The geared motor is kinematically connected to rack gearboxes mounted on trusses in the central part of the greenhouse. The shield is opened (closed) as necessary remotely using button or in automatic mode.
Drippers and capillaries
One of the most convenient forms of irrigation in closed ground conditions is drip watering. Mats with a substrate are often used as a medium for growing various types of vegetables (cucumbers, tomatoes, etc.). The nutrient solution in the mats with the substrate is served using droppers.
There are many versions of the dripper itself, which choice depends on the type and volume of the surface to be watered (for example, the size of the pot or other container), the needs of the plant itself, etc.
The automated microclimate control system is designed to control the climate in the greenhouse and monitor the external weather conditions, analyze the data and carry out calculations to maintain the specified microclimate and СО2 concentration in the greenhouse. The developed operating modes of the system allow coordinated control of heating circuits, ventilating windows, feeding СО2, a curtaining system, fans for forced air circulation and other operations depending on the specified parameters.
