Quality policy

Dedicated to an improvement policy of all the functions and operations



ASCENSORES TRESA develops its business activities following a solid environmental policy that covers the entire useful life of the product.
During the manufacturing process, the minimum controlled environmental impact is produced through energy efficiency audits, with the implementation of technological improvements available in each phase and with a rigorous waste management process. Strategically, it is committed to responsible technologies, such as lighting by means of LEDS, and the use of recyclable components at the end of the lifespan of each lift.

  • Lighting by means of high-performance LEDS, combined with automatic switching offon of the cabin light saves electricity.
  • By adopting the frequency convertors (VVVF) as standard for all electric lift models, ASCENSORES TRESA configures these installations with very low power consumption and reduced starting torque compared to the two usual speeds.
  • In the reliable and robust hydraulic technology, with the use of electronic regulators and frequency variators (VVVF) a reduction in energy consumption of more than 20% is obtained.
  • At the end of the lifespan of each lift, when replacing it, the different components are treated by reduction or recycling, thus reducing the environmental impact.
  • TRESA'S MAINTENANCE SERVICE keeps the lifts under its responsibility in optimal technical conditions of service, which translates into environmentally efficient operation. Fleet vehicle management is also eco-efficient, choosing the one that best suits each task, optimizing routes and instructing personnel on driving efficiently.
