What’s Included

The kit includes everything required for installation:

• DROP LT metal window frame

• polycarbonate panel

• Thermovent automatic window opener

Together, these components create a complete automatic ventilation system, eliminating the need for manual opening and closing.

DROP LT Window Features

Perfect Compatibility

The window is designed specifically for DROP LT series greenhouses, integrating seamlessly with the greenhouse structure.

Durable Galvanized Frame

The window frame is made from strong galvanized steel, just like the greenhouse frame itself.

This provides:

• excellent resistance to humidity

• long-term corrosion protection

• reliable structural strength

Efficient Ventilation Design

The window features a top hinge mounting system, allowing hot air to naturally escape from the upper part of the greenhouse.

Polycarbonate Panel Included

The window is supplied with transparent cellular polycarbonate, ensuring excellent light transmission while maintaining durability.

Thermovent Automatic Opener Features

Fully Autonomous — No Electricity Required

The Thermovent opener works using thermal expansion technology.

When the temperature rises:

• the liquid inside the cylinder expands

• the piston opens the window automatically

When the temperature drops:

• the liquid contracts

• the window closes automatically

No electricity, wiring, or batteries are required.

Smart Climate Regulation

The mechanism automatically starts opening the window between +15°C and +25°C, ensuring optimal greenhouse ventilation even when you are away.

Powerful Danish Mechanism

The opener uses a high-quality Danish hydraulic cylinder, capable of lifting window panels weighing up to 7 kg.

Excellent Air Circulation

The opener allows the window to open up to 45 cm, providing efficient airflow and rapid heat release from the greenhouse.
