About us

We are an Italian company with 40 years of experience in the air treatment sector: since 1981 we have been offering innovative products for the air conditioning of domestic, commercial and industrial environments.

Our customers are retailers and installers. We provide them with all the support they need to guarantee end-user satisfaction, always paying the utmost attention to the feedback provided.

Our long-term goal is to combine comfort, efficiency and sustainability in every environmental context and for all types of users. Hundreds of partners in Italy and around the world confirm that we are on the right track.

Sales Network

MITSUI, in its continuous research and development of new products, has a staff of highly specialised technicians and engineers.
Supporting this team are laboratories, technical offices and research centres using sophisticated technologies with state-of-the-art research and development programmes.
The use of selected raw materials, together with a long and laborious testing phase in research laboratories, ensure our products’ high quality and reliability.

Certified quality

We are ISO 9001 certified – the world standard for quality management in business, universally adopted in organisations of all sectors and sizes.

All machines in the Mitsui catalogue comply with current safety and sustainability regulations.

In particular:

  • The energy label helps the purchaser assess the efficiency and environmental impact of the product at a glance.
  • The CE mark certifies its compliance with current European Union regulations, guaranteeing quality and safety.
  • The entire range complies with the RoHS directive, which restricts the use of hazardous substances in electrical and electronic equipment.

The product

Our product speaks Italian: the design and supply of the raw material are the result of Italian tradition, inventiveness and design.

Mitsui has and offers not only technologically advanced systems, but also aesthetically intriguing and exclusive products. Mitsui focuses its attention on continuous research between design and functionality.

As a result, the products are practical and effective but at the same time aesthetically refined and elegant so as to fit in with any style and living environment.
If previously these appliances were stored in covered spaces, now, on the contrary, they can be displayed.

After-sales service

Mitsui is constantly working to train its distributors, designers and installers.
Staff training is a priority and valuable investment for Mitsui. Promoting the preparation of our staff is essential in order to provide a service that is adequate and responsive to every request and need of the end user. This training takes place at the company itself, by qualified personnel.
This makes it possible to have at one’s disposal a wide range of equipment on which to carry out real tests and simulations to also touch and put into practice what is explained at a theoretical level. Training is therefore essential in order to improve product performance, plant operating life, reduce operating costs and meet customer requirements.

Mitsui has also created over the years an extensive network of professional partners and service centres located throughout Italy to offer adequate technical assistance in the shortest possible time.
