Rittal is extending its current TopTherm generation of fan-and-filter units by adding a new air throughput class of 900 m3/h, equipped with energy efficient EC (Electronic Commutation) technology.
This innovation makes use of diagonal fan technology (air throughput ranging from 20 to 700 m3/h) - a synthesis of radial and axial fan technology that favours an even distribution of air within the enclosure, preventing the formation of hot spots. In addition to its flat design, it also features a steeper curve and higher pressure resistance.
To ensure greater security for the climate control of enclosures, the new TopTherm filter fan can be monitored and regulated via an optional eco-control unit. In the event of a fan defect, an error message is actively triggered via the fan's tacho signal.
Several fan-and-filter units can be seamlessly bayed to one another without leaving any disturbing gaps, with a choice of 230 VAC 50/60 Hz and 115 VAC 50/60 Hz supply voltage. The fan-and-filter unit's protection category can be increased from IP 51 to IP 56 by using a hose-proof hood. An EMC version is also available.
