Our commitment

There are numerous advantages for the environment that result from the use of the technologies produced by ErreDue: working for the efficiency and optimization of the production cycle generates important benefits not only for the customer but also for the environmental context in which the customer operates.

Here are SOME

  • On-site gas production eliminates greenhouse gas emissions from cylinder transportation.

  • On-site production of gas directly at the required pressure provides significant energy savings and can eliminate the need for a compressor.

  • Hydrogen used as an energy carrier enables the best use of existing renewable sources and facilitates their development and deployment.

  • Increased safety in working environments: the risk of accident is reduced because the gas produced at the pressure averts the danger of bursting and eliminates the critical issues associated with transport and handling of compressed gases.
