Have you ever thought?

A permanent-electro system consumes about 2.7% compared to a traditional electromagnet of the same capacity.
Assuming an average of 90 movements per day, the saving in 1 year is estimated at over 6,000 $!

	Electromagnet	Permanent-electro
Consumption kWh	15	18
Operating hours per day (*)	9	0.25
Consumption per day kWh	135	3.6
Annual consumption kWh (**)	3,750	900
Annual energy cost $ (***)	6,358	152

(*) 90 translations, average duration 6 minutes
(**) Year with 250 working days
(**) Cost kWh: 0.19 $

In addition, a permanent-electro system allows additional savings due to lower maintenance:
– does not require back-up batteries (with electromagnets the batteries must be checked and replaced periodically)
– it does not overheat, therefore it does not wear out (the windings of the electromagnets suffer from performance decay)

All TECNOLIFT handling systems are permanent-electro.
