about us :
ETT is a family-owned company based in Ploudalmézeau, at the western tip of Finistère, France. Recognized as a major player in the HVAC market, the company continues to grow, recruit, and expand its presence.
As a French manufacturer of high-performance energy recovery air treatment systems and heat pumps, ETT has positioned itself as a key player in the wind energy sector through its partnerships with various EPCs (Engineering, Procurement and Construction).
ETT is the leading French supplier of air conditioning and pressurization solutions for offshore wind sub-stations.
These platforms are uninhabited, and offshore interventions are extremely costly, making reliability and longevity essential factors in design and component selection.
By integrating advanced technologies, high-quality components, and best practices, we ensure high-performance, energy-efficient services that comply with the most stringent standards.
With a wide range of equipment, ETT offers both standardized and customized solutions designed to withstand marine environments. Various materials and options are available to meet these requirements.
Our HVAC unit designs prioritize maintenance, repairability, durability, and performance, even in highly corrosive environments.
ETT’s environmental policy has been ISO 14001 certified for environmental management since 2010.
As a responsible economic player committed to continuous improvement, our primary duty is to prevent pollution risks and minimize our environmental impact.
Since 2022, ETT has voluntarily undertaken its GHG Scope 3 assessment. We are now committed to implementing a decarbonization plan for our site and technologies. In addition to our existing environmental performance management actions (ISO 14001, energy audits, mobility plans), we strive for product and service excellence by supporting our clients in their energy transition.
Our expertise in climate control and air treatment solutions allows us to offer performance monitoring services and energy consumption reduction strategies. In 2025, ETT was awarded a gold medal with a score of 79/100, ranking us in the top 5% of companies assessed by ECOVADIS.
