Toptherm EC fan and filter unit

Rittal is offering a more energy-efficient means of ventilating enclosures by supplying electronically commutated (EC) versions of the Toptherm fan and filter unit, in all but the very smallest size.

Using the same diagonal fan technology as the standard variant, Rittal Toptherm EC fan and filter unit is claimed to provide improved performance against static pressure, offering a more constant air throughput and energy savings in excess of 60 per cent over previous models.

Compliance with ongoing energy efficiency guidelines can be met and exceeded by using EC motors, while intelligent control and fan status monitoring is available for larger units.

The risk of component failure in the enclosure is minimised by the direct monitoring of fan speed via a tacho-signal output with a malfunction of failure signal, which prompts immediate action.

Key features and benefits:

• Toptherm provides improved performance against static pressure.
• It offers energy savings in excess of 60 per cent over previous models.
• It exceeds energy efficiency guidelines.
• Infinitely variable speed control offers a means of conserving energy further by operating the fan at a speed determined by the demand for cooling.
• Programmable logic controller may be used to control the fan motor, via a 0–10VDC or pulse-width-modulated signal.
• There is a minimised risk of component failure in the enclosure.
