Using diagonal fan technology, Rittal has succeeded in creating an intelligent synthesis of radial and axial ventilation in its new TopTherm fan-and-filter units. The new fan technology is characterised by the fact that the air outlet direction is not in the fan's axial direction but instead diagonally to the outside. This favours an even distribution of air in the enclosure or housing, and avoids the formation of hot spots. In addition to the flat design, the key benefits are the steeper curve and the higher pressure saddle. As a result of this, the system has got higher pressure stability and – when installed and under operating conditions – provides a higher and more constant air flow over a wide area.
