Cold environments - Proven reliability of swing door operators

Cold environments - Proven reliability of swing door operators

Swing door operators are characterised by their reliable performance, which makes them energy efficient with a high level of user convenience. However, extremely low temperatures may have a negative effect on their reliability. The viscosity of the hydraulic fluid within the electrohydraulic operators rises, which increases the resistance within the hydraulic system. Therefore the opening and closing speed decreases and the door may not close properly. As a result, precious energy is wasted as the climate barrier between the interior and exterior of the building is no longer provided.

This results in:
Energy loss from open doors
Decelerated opening and closing cycles
Temperature related adjustments required

ED 100 and ED 250 electromechanical swing door operators provide reliable performance even in cold environments. Instead of a closed hydraulic system, these operators are equipped with a multi-stage gear, which only requires a low amount of high-performance grease to provide full performance. Therefore ED 100 and ED 250 operators are extremely durable - even in cold environments. In addition, their integrated Initial Drive Control (IDC) ensures functional stability as the system detects and compensates for even the slightest irregularities in the door's performance.

Benefits:
Smooth performance despite low temperatures
Reliable closing
No temperature related adjustments required
