Climate Systems
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:
- Cools and evenly distributes air in the greenhouse
- Promotes optimal plant growth, increased production rates and quality
- Dehumidifies the greenhouse area
- Reduces the risk of fungal diseases
Recirculation Fans
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.
Screening Systems
Energy efficiency and sustainability
Shading
Energy-saving
Blackout
How they work:
- Made of special aluminum foils, these screens promote light diffusion, stimulate plant growth, and prevent overheating of the upper layers of air.
- The latest advancement includes multiple-layer screens with separate mechanisms for shading and energy-saving, maximizing efficiency.
- For plants needing extended darkness, blackout screens create artificial nighttime inside the greenhouse.
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.
Heating System
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:
- Designing "Closed/Semi-Closed" greenhouse units
- Using renewable energy sources like biomass, geothermal energy, and solar panels
- Implementing energy-saving techniques, such as thermal screen shading systems and reduced ventilation through the CO2 supply
- Installing Cogeneration Plant units (CHP)
- Utilizing climate control software that calculates energy consumption and optimally coordinates individual systems to minimize energy costs.
These approaches promote sustainability, reduce reliance on fossil fuels, and achieve cost-effective energy management.
Boiler-Burner Selection
Pipe Heating Installation
Greentech provides reliable piping systems that ensure uniform heating throughout the greenhouse and boost productivity.
- Ground and sidewall pipes and/or air heaters are strategically combined for optimal results
- Ground pipes serve as rails for harvest trolleys and other logistic equipment, improving productivity
- Ground pipe rails are crucial for enhancing personnel performance in modern greenhouse facilities across the globe
