A greenhouse screen system is essential for managing light, temperature, and energy efficiency. It typically uses horizontal or vertical screens to control shading, thermal retention, or light diffusion within the greenhouse.

Greenhouse Screen Systems includes:

Shading Screens: Reduces excess sunlight and prevents plant stress due to overheating.

Common shading percentages: 30%, 50%, 70%, depending on crop needs.

Thermal Screens: Helps retain heat during colder months, reducing heating costs.

Reflects thermal radiation back into the greenhouse at night.

Blackout Screens: Blocks all light for crops requiring strict photoperiod control (e.g., flowering plants like poinsettias or cannabis).

Energy-Saving Screens: Dual-purpose screens that provide shading during the day and thermal retention at night.

Screen system we can offer:

We offer two kinds of screen drive system:

1 Rack and pinion drive system for horizontal screen;

A rack and pinion drive system can be an effective solution for operating horizontal screens in a greenhouse. These systems are commonly used in retractable shading, thermal curtains, or energy-saving screen applications.

The mechanical system mainly consists of components listing:

Rack and Pinion

Rack: A straight gear with teeth along its length, mounted parallel to the screen's movement direction.

Pinion: A pinion box engages with the rack, mounted on the drive shaft.

Motor Gearbox, typically with limit switch to drive the rack and pinion system for smooth operation.

Support Structure: A frame or track system to guide the rack and keep it aligned during operation.

Screen Material: Lightweight, UV-resistant fabric or mesh to provide shade, thermal insulation, or energy efficiency.

Tension System

A spring or cable tension mechanism ensures the screen stays taut and evenly deployed/retracted.

2  Cable driven system, use cable and pulleys for horizontal screen.

A cable-driven system is another common approach for operating horizontal screen systems in greenhouses, such as shading or thermal curtains. These systems use cables or ropes to move the screens and are valued for their simplicity, scalability, and cost-effectiveness.

Key components for cable driven system:

Cables/Ropes

Typically made of durable materials such as galvanized steel, stainless steel, or synthetic ropes (e.g., polyester or Kevlar) to resist wear and corrosion.

Motor gearbox and Winch drum

A motor gearbox with limit switch, drive the shaft tube with a winch or drum pulls the cables, moving the screen open or closed.

Pulleys: Low-friction pulleys guide the cables along the desired path and distribute tension evenly.

Screen Material: Lightweight, UV-resistant fabric or mesh to provide shade, thermal insulation, or energy efficiency.

Guide Rails and Support Structure: Frames or tracks support the screen and prevent sagging or uneven movement.

Tension System: Spring-loaded mechanisms, weights, or adjustable tensioners keep cables taut to ensure smooth operation.
