Ability Projects has introduced a series of DC powered 2 and 4 pipe fan coil units – called Evolution – and using ebm-papst’s latest EC (electronically commutated) variable speed DC motor technology.

The use of Ability’s EC fan coil packages can reduce energy use levels and running costs for commercial air conditioning systems. At a typical fan coil duty point, the Ability EC configuration can reduce electrical input by 50- 75%. A typical fan unit will draw 60W when powered by EC motors where previously it would have taken 210W in an AC format. Ability EC motors also run cold and do not generate motor heat.

The new EC motor has a built-in AC to DC power converter that converts 230V AC input to DC output to the fan via its EC power supply circuits. This means that while the motor runs on DC power, the supply to the motor is still 230V AC, this makes installation easier.
