Overview – A Faster Electric Window Opener for Sudden Rain

What happens when a sudden rainstorm arrives and your windows are still open, or when a rain sensor is installed but the electric window opener system reacts too slowly?

This is a common issue in modern window actuator systems. Most products on the market operate at a fixed speed , which makes them unable to respond quickly in emergency weather conditions.

Even when a rain sensor is triggered, the slow window opener motor system cannot close the window in time, allowing rainwater to enter the building.

To solve this problem, JUJIANG GIANT developed the KCQ-B03 automatic window opener, designed for fast response and reliable smart window control.

Powerful Electric Window Opener Performance

The KCQ-B03 is equipped with a 12V DC motor powered by a digital transformer, delivering:

35W rated power

Up to 3500N thrust output

Supports heavy-duty windows up to 200kg

Suitable for industrial ventilation systems

This makes it a powerful window opener actuator system for residential, commercial, and industrial applications.

Despite strong force output, the window opener maintains smooth and stable movement without delay.

Adjustable Speed Window Opener System

Unlike traditional fixed-speed systems, the KCQ-B03 automatic window opener supports adjustable speed control.

Standard operating speed: 2.5 cm/s

High-speed closing mode: 0–5 seconds adjustable

Users can switch between:

Fast emergency closing for rain protection

Normal speed for daily ventilation and energy saving

With a remote control range of over 50 meters, this smart window opener system is suitable for homes, greenhouses, factories, and large buildings.

Smart Safety – Anti-Pinch Window Opener System

The KCQ-B03 electric window motor system includes adjustable obstruction sensitivity:

Anti-pinch protection for users, pets, and objects

Prevents false stops caused by heavy window  

Compatible with both light and heavy window systems

This ensures safe and reliable operation in all window actuator applications.

Rain Sensor Compatible Automatic Window Opener

The KCQ-B03 supports external rain sensor integration with a dedicated 5V power output.

Once rain is detected, the automatic window motor system will immediately activate closing mode. Combined with high-speed operation, it ensures fast protection against sudden weather changes.

This makes it a fully automated smart electric window opener solution for unattended environments.

Durable Design for Long-Term Use

Designed for outdoor and industrial environments, the KCQ-B03 window opener actuator features:

Helical gear transmission for low noise and high efficiency

IP55 protection against dust and water

Operating temperature: -20°C to +50°C

Long service life for continuous use

It performs reliably in harsh weather conditions, making it ideal for long-term automatic window opener installations.

Customer-Driven Innovation

With over 20 years of experience in electric window opener systems, JUJIANG GIANT continuously improves product performance based on real user feedback.

The KCQ-B03 was developed to solve key problems such as slow response time, heavy window load handling, and unreliable rain sensor reactions.

The result is a faster, safer, and more intelligent automatic window opener system, built for modern smart buildings.
