Rittal’s range of TopTherm fan and filter units has been further expanded with the introduction of a 230V AC 900m3/h variant. The entire range of fan and filter units utilise a diagonal fan to provide improved performance against increased static pressure difference. In turn, this offers greater energy efficiency and a more constant air throughput – minimising the occurrence of hot spots. The new product is also fitted with an electronically commutated (EC) motor to further reduce power consumption.
Energy efficiency of the TopTherm fan and filter units fitted with single-phase AC motors may be improved in operation by the addition of either a simple thermostat or more sophisticated fan speed control. Rittal’s speed controller adjusts the speed of the fan in accordance with the demand for cooling – reducing noise and energy consumption when cooling is not required.
It also incorporates a fault alarm activated in the event of the temperature of the air inside the enclosure rising above a predetermined level, an interruption in the supply to the fan, a sensor short circuit, or a failure in the supply to the controller itself. This device increases maintenance intervals, reduces energy consumption and alerts users to potential problems.
