Automatic opening of heavy weight linear sliding doors in excess of 400kg.

The robust STA 22 automatic door is particularly suitable for special entrances and applications, which require heavier door leaves. The operator technology in this model is particularly stable and reliable and has maintained its position successfully in the market for many years.

The STA22 has opening widths of 850mm to 4,000mm and can accommodate door weights of up to 1 x 300kg, or 2 x 250kg at 100% duty rating.

Using the RECORD system 20, the STA22 which has been developed using modular construction principles. This allows the system to be adapted safety and efficiently to a wide range of conditions using the same precision-crafted components. This results in benefits for the customer of shorter installation times and reduced service and maintenance costs.
