Energy efficient cooling using ambient air

Listen to this article

Rittal continue to expand their range of TopTherm fan and filter units with 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, effectively 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.

Not only does this device increase maintenance intervals and reduce energy consumption, it also alerts users to potential problems.

Most of the existing range of TopTherm fan and filter units are available with 24V DC motors, which exhibit a significant reduction in power consumption over the 230V AC and 115V AC motor variants.
