Managing temperature is the key to successful crops
Creating the most fertile environment possible
Low humidity leads to excessive transpiration and crop damage. On the other hand, extremely high humidity creates the ideal breeding ground for fungal infections and diseases, putting plants at risk.
Pad & Fan Cooling System
The prevailing greenhouse cooling solution
Pad and fan cooling systems work by using evaporative cooling to reduce temperatures inside greenhouses. It is a highly effective system for greenhouses in Greece, particularly in areas with medium to high humidity levels. It safeguards the optimal conditions for plant growth even during hot summers with wild temperature fluctuations.
By utilizing this cooling system, producers can maintain production levels while others may struggle, giving them a competitive advantage and the opportunity for significant profits.
Advantages of Pad & Fan cooling systems:
An essential component for regulated temperatures
Key to consistent crop development, recirculation fans distribute air, reducing water vapor on leaves to prevent diseases. They eliminate hot air pockets and minimize heat loss during winter. Moreover, they aid CO2 distribution for optimal plant absorption and prevent temperature variations from the heating system.
Fog: High-Pressure Cooling System
Industrial humidification with incredible precision
A fog cooling system uses stainless steel pipes and specialized nozzles to release a fine mist that reduces temperature and increases humidity in greenhouses. It operates at a pressure of 60 to 70 bar and integrates seamlessly with the central climate control system for precise control and optimization.
Fog: Low-Pressure Cooling System
Cost-conscious cooling and moisture regulation
A low-pressure cooling system is a cost-effective solution for moisture problems. It is installed on the greenhouse roof and uses plastic nozzles on tubes to create small droplets. The system operates at a nozzle pressure of 4 to 6 bar and a specialized controller prevents plants from getting wet.
Energy efficiency and sustainability
How they work:
CO2 Supply System
CO2 is crucial for plant growth and production through photosynthesis. Maximizing CO2 levels enhances plant activity, increasing greenhouse productivity
High CO2 concentrations reduce daytime ventilation, capturing more energy for nighttime heating, saving costs.
In leafy crops like tomatoes, CO2 supply is recommended, even during ventilation provided there is no strong air streaming. It can be used independently, with open or closed windows, and artificial lighting. The central computer enables easy control and setting of the CO2 supply, with alarms for minimum and maximum concentrations.
Greentech offers reliable and smart heating systems for high-quality production. The system is perfectly balanced and controlled through a climate control computer.
Heating sources can be boilers fueled by liquid, solid, gas, or hot water from geothermal sources. Circulation pumps and a network of pipes distribute hot water throughout the greenhouse, with the option of water-air heaters for precise control.
Total Heating Control
The climate control computer regulates the heating system, maintaining optimal greenhouse temperatures. Ground and peripheral pipes, along with air heaters if needed, ensure optimal plant growth. The heating systems work together, activating the secondary system when an additional temperature increase is required.
Greentech’s heating systems meet building codes, Greek official standards, and international guidelines to ensure high efficiency and optimum energy conservation.
Savings in energy and fuel
Several methods have been employed to save conventional fuel in greenhouses:
These approaches promote sustainability, reduce reliance on fossil fuels, and achieve cost-effective energy management.
Pipe Heating Installation
Greentech provides reliable piping systems that ensure uniform heating throughout the greenhouse and boost productivity.
