ECQ internal rotor motor

In the past, fans used in refrigeration units were predominantly propelled by shaded pole motors. These motors have an incredibly low energy efficiency of around 18%, meaning that 82% of the energy is transmitted to the cold chamber as waste heat. This results in increased cooling requirements and energy consumption. In contrast, the extremely efficient ECQ motor range from ZIEHL-ABEGG has a level of efficiency of up to 65%. As a result, these motors counteract the huge amount of thermal loss and are considerably more frugal with their energy consumption. Three speed steps can be freely programmed via a USB port. This offers up the opportunity – particularly in the field of retrofitting – of easily converting existing units into the new energy-saving technology, thereby saving money.
We also offer our efficient ECQ motors with ATEX certification for use in explosive areas, e.g. in environments with highly flammable gases or dusts.
