Uusi Enersense, uudet verkkosivut!

Kolme oman alansa edelläkävijää - Enersense, Empower ja Värväämö - yhdistyivät ja toimimme nyt yhteisellä Enersense-nimellä. Samalla myös verkkosivumme yhdistyivät ja uudistuivat.

Vaikka ulkoisesti näytämme erilaiselta kuin ennen, palvelemme tuttuun tapaan kaikkien yhtiöidemme asiakkaita, työntekijöitä ja muita sidosryhmiä.

Värväämön palvelut löydät sivuilta Staff Leasing -nimen alta. Kirjautuminen Like.it-järjestelmän löytyy sivujen oikeasta yläkulmasta.

Olethan yhteydessä yhteyshenkilöösi mahdollisissa kysymyksissäsi!

Motor concept

In Enersense’s motor concept, the size of the spare motor stock is chosen to match the requirements of the customer company’s production. The concept utilises data analysis that allows us to optimise the value and functionalities of the customer’s motor stockpile.
Data analysis based on facts and actual results allow us to reduce the size of the motor stockpile, release capital and significantly improve the positive environmental impact. Our motor concept includes:

  • Factory stockpiles of common and critical motors for ensuring reliable deliveries and operation.
  • A central warehouse operating with the motor pool principle and including a smaller, optimised number of motors in stock. Capital is released for other purposes without compromising the availability of production.
  • Optimised logistics means less transport and reduced use of fossil fuels, smaller storage facilities and less heating of facilities.
  • Digital real-time views of the spare motors available for optimising the reliability of operation.

Maintenance, repair and polishing services for rolls

The holistic roll replacement and maintenance service ensures the good operability of rolls, extends their mechanical service life, shortens the downtime required to replace them and reduces the disruptions caused by rolls.

Roll replacement

Our mobile roll replacement team takes care of planning the roll replacement operations to be carried out during downtime, performs the replacements and produces the reports.

Roll maintenance

Roll maintenance is carried out by a maintenance team specialising in roll maintenance. The maintenance team has long experience of roll maintenance and polishing.

Outsourcing the maintenance centres

Enersense assumes responsibility for the customer’s maintenance centre and machine shop services. The service creates an operating model that ensures the availability of service, while operating efficiently and minimising any idle time at the machine shop. Efficiency is guaranteed by Enersense’s multi-customer environment, where the machine shop is a cost-effective maintenance centre independent of equipment suppliers, and always ready to serve both the outsourcing organisation and external customers.

Maintenance centre

We are responsible for the work planning of the maintenance centre in a multi-customer environment, ensuring the high utilisation rate of maintenance centre machines and the minimising of excessive waiting time for personnel.

Storage facility

We provide an opportunity to reduce the capital tied in the stockpile when the maintenance centre is outsourced. The repair cycle of machines coming in for maintenance can be prioritised when the stockpile is optimised by determining its optimal size on the basis of data analysis.

Responsibility for equipment category

We take responsibility for a clear entity in which the high availability of a certain equipment category is guaranteed. At the same time, a spare equipment service is created for the customer using the equipment in the category. This is a machine bed to machine bed service, in which we are responsible for the overall process including preventive maintenance, and for replacing any failed equipment with operational new or repaired equipment.
