What Is a GW GeWalt Automatic Sliding Door?
Our automatic sliding door systems are engineered around the HH150 worm-gear mechanism and a 100W BLDC motor rated to 200kg per leaf. They are built for hospitals, malls, offices and premium residences where downtime is not an option and a jammed entrance costs real money.
A microwave motion sensor detects an approaching person and signals the microprocessor controller. The controller drives the tooth belt, the leaves glide along the guide rail on hanger brackets, and an infrared safety beam holds the door open while anyone stands in the threshold. Anti-clamp technology reverses the leaf the moment it meets resistance, in line with the EN 16005 approach to powered door safety.
Engineered to the 4S Principles
Every system follows the four rules we have refined over 29 years. Stable: three wheels on two tracks keep the leaf square. Safe: anti-clamp sensing plus a backup battery pack. Silent: specialized rubber design absorbs contact noise. Strong: a continuous-duty BLDC motor that does not fade under high traffic.
Advanced options include an LCD display, working-time counting, timer control, PC integration and the chemist’s shop function, which opens the door part-way for secure after-hours service.
Where These Doors Earn Their Keep
High-traffic retail entrances, hospital corridors, government buildings and office lobbies are our most common installations. As a certified installer for Malaysian government and high-security commercial buildings, we also specify breakout hardware and compliance details where escape routes are involved. For a worked example, read how we upgraded a failing high-traffic commercial entrance to a 4S system.
