In addition to integrated heating and cooling via our thermodynamic system, it's possible to add supplementary equipment such as:
- Condensing gas modules
- Direct or indirect adiabatic coolers
- Chilled water, hot water, steam or CO2 coils
- Electric preheating, heating and auxiliary coils
Many industrial applications require ambient humidity regulation. This involves implementing equipment to dehumidify or humidify the air, such as:
- Thermodynamic or desiccant dehumidification
- Steam humidification with or without integrated production
Energy efficiency is a key concern for manufacturers. To this end, ETT can integrate various equipment and control features such as:
- Thermal wheels, plate heat exchangers, heat pipes, glycol coils
- Free cooling management
Managing air flow is essential for proper industrial process operation:
- Air turnover rate / homogenization of temperature and humidity conditions
- Fresh air compensation (process extraction)
- Positive or negative air pressure management
- High pressure air supply
Numerous constraints often require machines to be designed for integration into their environment. ETT's flexibility allows for:
- Custom dimensions and multi-block design
- Reinforced casing
- Anti-corrosion treatment of components and casing for harsh environments
- Aluminum or STAINLESS STEEL casing, paint finish
- Adaptation to acoustic constraints
Air quality is an important factor for operator comfort and production quality, requiring equipment for:
- Particle and molecular filtration
- Fresh air management
- ATEX (explosive atmosphere) risk management
Recent regulatory developments, particularly the F-Gas regulation, strongly encourage the use of natural refrigerants.
For several years, ETT has been incorporating Propane (R-290) as a refrigerant in various types of machines (air and water-based) such as:
- Air-to- Air heat pumps
- Chillers up to 1.2 MW
- Heat recovery chillers
- High temperature heat pumps up to 70°C
Special attention must be paid to equipment control to meet manufacturers' expectations. This is why ETT develops all of its algorithms to offer customized operation.
Additionally, the myETTvision supervision tool allows manufacturers to monitor their machines remotely and in real-time.

Dedicated solutions
High-performance, sustainable solutions for the electrical and electronics industries
The sector is made up of a multitude of SMEs as well as large companies. Around 200 key companies are active in the manufacture and distribution of electrical and electronic components in France.
In France, the production of electronic and electrical components is a major pillar of the economy. The sector currently employs around 100,000 people
Regulations
In France, regulations on air treatment in factories producing electronic and electrical components are strict in order to guarantee product quality and worker safety. The main standards include:
- ISO 14644: This international standard governs cleanrooms and specifies classes of air cleanliness based on the number of particles per cubic metre.
- REACH regulations (Registration, Evaluation, Authorisation and Restriction of Chemicals): Imposing restrictions on the use of chemical substances that are potentially hazardous to health and the environment.
These regulations aim to reduce the environmental impact of plants producing electronic and electrical components, while improving energy efficiency and guaranteeing a safe and healthy working environment. Companies must put in place appropriate management systems and invest in advanced technologies to comply with these requirements.
