DUAL-Électrotech is a leader in the customization and optimization of products and services in electrical distribution. Its mission is to realize and integrate complete solutions in low, medium and high voltage, thanks to a flexible approach.


DUAL-Électrotech’s ambition is to become the reference in the implementation of customized electrical distribution solutions. With our qualified personnel, we aim to serve our customers from engineering to operation, including long-term maintenance, in a spirit of optimal safety.


DUAL Electrotech, founded in 1995, specialized in personalized medium and high voltage electrotechnical services;


ADE Technologie, founded in 1996, specialized in the custom design and manufacturing of low and medium voltage switchgear.


DUAL Électrotech is increasing its expertise in oil analysis through its continuing education program and by acquiring software that allows it to refine its analyses and recommendations.


The two companies merge and become DUAL-ADE Technologies inc.


Our manufacturing department obtains its first ISO certification through the implementation of the quality assurance system. Today, its processes are supported by the ISO9001:2015 quality management system.


Our electrotechnical services department develops an oil filtration and dewatering unit, which can be operated under voltage. This is an interesting offer for our customers since no production stoppage is required during the treatment.


DUAL-ADE marketed its new MODU-AL design, which is used in manufacturing its switchgear cabinets. Its design and layout flexibility allow it to offer custom designed switchgear, which meet the needs of its clientele while easily adapting to the limited space of their sites.

The electrotechnical services team is involved in the reconstruction of hydroelectric power plants in Haiti, namely the Onde Verte and Sault-Mathurine plants.


DUAL-ADE joined the NSERC-Hydro-Québec-UQAC Industrial Research Chair on Atmospheric Icing of Power Network Equipment (CIGELE). This partnership made it possible to find innovative solutions to counter the hardships of our Nordic winters and prevent the accumulation of ice on our switchgear cabinets. This new innovative technology will be limited to the partners of the Chair. The only SME associated with CIGELE, DUAL-ADE is expanding its offer by making this new surface treatment available to its clientele as of 2015.


DUAL-ADE officially adopted a participative management method. This new organizational culture allows it to guide its actions and decisions while respecting its corporate values – placing it at the forefront in human relations. With technology that is increasingly turning to virtual contacts, DUAL-ADE is committed to taking up a significant challenge: increasing and prioritizing its interpersonal relationships with its employees, clients, suppliers and partners.


DUAL-ADE purchased a building and moved into its new premises. This acquisition allowed it to triple its production area to meet the increasing market demand. Located on 21 acres of land in the heart of the Sherbrooke Industrial Park, this new environment fosters the creativity of its employees, who are more committed than ever to innovation, solutions and action.


DUAL-ADE implemented a new process and aims for operational excellence. All aspects of the operations are affected and continuous improvement, inspired by Toyota’s Lean Model, is at the basis of this philosophy. It supports the new organizational culture since it involves employees at all levels in the search for new processes. Operational excellence helps DUAL-ADE push its limits and allows it to implement new ways of doing things and to “Think Outside of the Box”.


Our Manufacturing Department launches a new product that promotes employee safety during circuit breaker operations during annual maintenance: it’s a universal cradle that can be operated remotely.


As the company acquires a strong reputation both for the manufacture of its electrical switchgear and for its electrotechnical services, we decide to distinguish our two business sectors of activities by two legal entities. The manufacturing sector still operates under the banner of Technologies DUAL-ADE Inc., while the service sector now operates under the banner of DUAL-Électrotech Inc.


DUAL-Électrotech acquires a purification unit for insulating oils. The treatment of the oils by this purification unit extends the duration of the life of your transformers, since the unit dehydrates, eliminates the gases, and removes contaminants in a single operation. At the end of the treatment, the regenerated oil regains the physical and electrical properties of the new oil.


DUAL-Électrotech inaugurates its new offices. The workspaces and the meeting and discussion areas are designed according to a concept that promotes dynamism, creativity, cohesion, and teamwork.


This year is a year of great change. DUAL-Électrotech obtains its first ISO certification by implementing the quality assurance system. These processes are supported by the ISO9001:2015 quality management system.


In January 2023, following a strategic reflection, we decided to increase our efforts with our DUAL-Électrotech customers to increase our offer. We will therefore focus our efforts on electrotechnical services. Our decision is supported by our desire to push our expertise in electrotechnical services even higher and to align with our mission and our vision of being the essential reference in the implementation of customized solutions for electrical distribution. We have also begun a process to be recognized as an eco-responsible company. These important changes are made in concert with our values: Rigor, Thinking Outside of the box and Communication.
