The semi-closed greenhouses by Richel Group: tailor-made solutions for healthy and sustainable production, without pesticides, that save resources and maximize yields.
The advantages of Richel Group’s semi-closed greenhouses:
In a context where sustainability and the quality of agricultural products have become top priorities, Richel’s semi-closed greenhouses offer an innovative solution. They enable producers to combine agronomic performance, environmental responsibility, and food safety. These greenhouses provide an optimal growing environment while reducing the impact of chemical inputs and preserving natural resources. Thanks to advanced climate management technologies and integrated biological pest control solutions, they set a new benchmark for more sustainable and profitable agriculture.
Richel’s semi-closed greenhouses are specifically designed to limit the infiltration of insects through a positive pressure system. Combined with integrated biological control, this system enables pesticide residue-free production, which is healthier for consumers. It also generates savings on the use of plant protection products for producers.
Farmers can adopt more natural pest control methods, such as using natural predators or biopesticides. The reduction of chemical inputs leads to healthier products that meet the expectations of consumers seeking quality and food safety.
The greenhouses are equipped with insect-proof nets placed over the air intakes on the gables or long spans. This centralized placement makes their monitoring and maintenance easier. A dynamic active ventilation system, coupled with heating and cooling systems, ensures optimal climate conditions from the roots upward. This ventilation dries the plants and limits the development of fungi and molds, such as mildew. Finally, a precise system for controlling humidity and temperature helps strengthen plant health and their resistance to diseases.
Compared to a traditional depressurized adiabatic cooling system, water consumption is reduced by half during hot periods!
Moreover, this type of greenhouse enables the use of low-temperature heating systems, contributing to further energy savings and reduced CO₂ emissions.
Lastly, they ensure increased production on a smaller surface area, preserving soil while optimizing yields.
Richel’s semi-closed greenhouses provide better climate uniformity across the entire growing surface, promoting optimal plant growth throughout the year. Our systems allow precise climate control, with cooling, heating, and dehumidification functions. Thanks to a reduced number of vents, shading zones are minimized compared to traditional greenhouses, providing more light for plants. Temperature distribution is also optimized, keeping the roots cool and the tops of the plants warm. Additionally, they increase CO₂ levels within the greenhouse, stimulating photosynthesis and plant growth.
Richel greenhouses can operate in different climate management modes to meet the specific needs of clients based on their geographical location, crops, and seasonality.
Outdoor air is drawn into the climate chamber and then distributed throughout the greenhouse via fans. This air can be cooled or heated as needed before escaping through the roof vents.
The indoor air of the greenhouse is recycled. It is drawn into the climate chamber, then heated, cooled, or dehumidified before being redistributed back into the greenhouse.
A combination of the two previous modes allows for precise regulation of temperature and humidity by mixing both indoor and outdoor air. In summer, the system primarily operates in open mode, providing effective cooling while protecting the greenhouse from insects. In winter, it switches to semi-closed mode, offering optimal management of dehumidification and heat to maintain a favorable climate for crops.
