Have you ever thought?
| Electromagnet | Permanent-electro | |
|---|---|---|
| Consumption kWh | 15 | 18 |
| Operating hours per day (*) | 9 | 0,25 |
| Consumption per day kWh | 135 | 3,6 |
| Annual consumption kWh (**) | 33.750 | 900 |
| Annual energy cost £ (***) | 5.709 | 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.
