China OEM Customized Cool Water Curtain System Cooling Pad for Greenhouse with Factory Price gearbox drive shaft

Product Description


Product Description

          Evaporative cooling differs from typical air conditioning systems, which use vapor-compression or absorptionrefrigeration cycles. Evaporative cooling works by exploiting water’s large enthalpy of vaporization. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). This can cool air using much less energy than refrigeration.

Detailed Photos

        Temperature dropping process is completed in cooling pad paper. There is a layer of thin water film on the surface of wave-shaped fibre paper. When dry hot air is pumped by cooling fan through cooling pad paper, water in film will absorb heat in the air and vaporize, take a lot heat away. So air temperature which is through cooling pads dropped. Cool wet air enters into room and was mixed with hot turbid and was discharged out of room through cooling fan.


  1. Made of corrugated fiber paper with the spatial crossing liking technology, high absorb ability, high water resistant, corrosion resistant and anti-mildew.
  2. High hygroscopicity: to absorb water naturally, with fast speed of pervasion and lasting effectiveness.
  3. Specific stereoscopic structure: supplying enough surface area for heat exchange of the water and air.
  4. No mico hole on the surface. No phenol in the raw material.

  1. Can be made of galvanized, aluminum alloy or stainless steel, beautiful andpractical, high-strength, easy to maintain and replace cooling paper.
  2. Processed antioxidant treatment, enhancing service life.
  3. Cooling paper is made of high quality corrugated fiber paper from Kiamusze. High hygroscopicity. Good refrigeration effect.

Ensuring Smooth Operation and Reliability of Greenhouse Gearboxes

Greenhouse gearboxes play a crucial role in maintaining optimal ventilation and shading systems. To ensure their smooth operation and reliability, several factors need to be considered:

  • Quality Construction: Opt for gearboxes from reputable manufacturers known for their quality construction. High-quality materials and precision manufacturing contribute to long-term reliability.
  • Sealed and Protected Design: Greenhouse environments can be humid and prone to dust and debris. Choose gearboxes with sealed and protected designs that prevent moisture and contaminants from affecting internal components.
  • Proper Lubrication: Regular and appropriate lubrication is essential for reducing friction and wear. Choose gearboxes that allow easy lubrication and follow the manufacturer’s recommendations for lubrication intervals and types.
  • Maintenance: Implement a regular maintenance schedule for your gearboxes. Inspect for wear, check lubrication levels, and address any issues promptly. Proper maintenance can extend the lifespan of your gearboxes.
  • Overload Protection: Some gearboxes come with overload protection features that prevent damage due to excessive force. This ensures the gearbox is not subjected to loads beyond its capacity.
  • Testing and Calibration: Ensure that the gearboxes are properly tested and calibrated before installation. This includes verifying gear ratio, speed, and accuracy to guarantee smooth and reliable operation.
  • Automation Integration: If your greenhouse uses automation systems, ensure that the gearboxes are seamlessly integrated. Compatibility with control systems and sensors ensures accurate and synchronized operation.
  • Professional Installation: Proper installation is essential for the reliable functioning of gearboxes. Hire professionals or follow manufacturer guidelines to ensure correct installation and alignment.
  • Training and Education: Provide training to the personnel responsible for operating and maintaining the gearboxes. Proper handling and care can significantly impact the longevity and performance of the gearboxes.

By considering these factors and following best practices for maintenance and operation, greenhouse gearboxes can deliver smooth operation and long-term reliability, contributing to the efficient functioning of greenhouse systems.

Contribution of Greenhouse Gearboxes to Energy Efficiency

Greenhouse gearboxes play a significant role in enhancing energy efficiency in greenhouse operations through various mechanisms:

  • Precision Control: Gearboxes allow for precise and controlled adjustments of ventilation, shading, and other systems. This prevents unnecessary energy consumption by ensuring that these systems operate only when needed.
  • Optimized Automation: With the use of automated greenhouse gearboxes, systems can be programmed to respond to changing environmental conditions. This prevents overuse of resources and ensures that energy-intensive operations are carried out efficiently.
  • Synchronization: Gearboxes enable synchronization of various greenhouse components, such as fans, louvers, and shades. This synchronization ensures that these components work together seamlessly, reducing energy waste due to conflicting actions.
  • Minimized Heat Loss: Gearboxes control the opening and closing of vents and windows. By optimizing ventilation, gearboxes help maintain optimal temperatures inside the greenhouse without excessive heat loss, reducing the need for additional heating.
  • Efficient Shading: Automated shading systems operated by gearboxes can regulate the amount of sunlight entering the greenhouse. This prevents overheating, reduces the need for cooling, and saves energy.
  • Consistent Irrigation: In some cases, gearboxes control irrigation systems. Efficient irrigation management prevents water wastage and helps plants receive the right amount of moisture, reducing the need for excess watering and related energy consumption.

Overall, greenhouse gearboxes contribute to energy efficiency by intelligently managing and optimizing various greenhouse systems, resulting in reduced energy consumption, lower operational costs, and environmentally sustainable practices.

Automation of Ventilation and Shading Systems with Greenhouse Gearboxes

Greenhouse gearboxes play a vital role in automating ventilation and shading systems, enhancing the efficiency of greenhouse operations:

  • Ventilation Systems: Gearboxes are integrated into automated ventilation setups to control the opening and closing of windows, louvers, and vents. By adjusting the gear ratios, these gearboxes enable precise regulation of airflow based on factors such as temperature, humidity, and CO2 levels. This automation helps maintain optimal growing conditions and prevents excessive heat buildup.
  • Shading Systems: Gearboxes are utilized in automated shading systems that provide protection from intense sunlight. These systems include retractable screens or shading curtains that can be controlled based on light intensity and time of day. Greenhouse gearboxes allow gradual adjustments to the shading level, preventing sudden changes that could stress plants. By automating shading, gearboxes contribute to maintaining consistent light levels and preventing overheating.

The automation of ventilation and shading systems using greenhouse gearboxes reduces the need for manual intervention, especially in large-scale greenhouse operations. Growers can program the gearboxes to respond to environmental conditions, ensuring that plants receive the right amount of fresh air and light without requiring constant monitoring.
