Maximising the performances of your rooftop units to reduce energy consumption in shopping centres

ETT is a French manufacturer recognised as the leader in air conditioning by the key players of the Retail sector (such as Auchan, Leroy Merlin, Ikea, and many other brands). Eurovent certified, the ETT packaged rooftop units not only ensure thermal comfort in your buildings, but they also leverage energy performance to drastically reduce your operating costs. Made of 100% aluminium, ETT units meet the weight constraints and are highly resistant to corrosion.

The French manufacture of the ETT units make for their reliability and durability.

As a store manager or contracting authority, an engineering consultancy, an installer or maintenance technician in charge of a shopping centre, you are certainly faced with the following issues:

  • Ensuring the customers’ well-being: because commercial buildings consist of several areas intended for different uses and therefore with different needs (food area, textile area, commercial gallery,…), ETT units directly treat inside air and help reduce the losses due to thermal exchanges. Your customers will benefit from the climatic comfort that underlies the pleasure of shopping. ETT places its expertise at your service by helping you choose the air conditioning system that best fits your project.
  • Controlling the fresh air in your buildings (management of Free Cooling and Free Heating): air treatment represents 70 to 75% of the energy bill. ETT developed a “Free Cooling” mode for optimised cooling efficiency and a “Free Heating” mode for optimised heating efficiency using outside air. External recovery systems can also be implemented to avoid using thermodynamic circuits. Each project is unique, and we know how to identify the constraints to adapt our technology to your energy constraints.
  • Reducing the operating costs: ETT has a complete command of the manufacturing process for air treatment systems with energy recovery and heat pumps, from design to production. This expertise allows us to design and include quality components for optimal reliability.

Our rooftop units can be associated with any type of diffusion system: textile ducts, rigid ducts, low speed diffusers. ETT communication system (myETTvision) allows centralised real time monitoring through a single IP address, giving technical services a permanent access to units operating data.

ETT Solutions

Greater comfort and lower energy bills

ETT designs, manufactures, commissions and maintains thermodynamic air conditioners. Those conditioners can operate as reversible heat pumps or for Cooling only, with outside air or water circulation (geothermal or water loop) as an exchange source. Eurovent certified, our rooftop units meet the requirements of Directive 2009/125/EC on the ecodesign of ErPs (Energy related Products). Our units are eligible for the French “CEE” energy saving certificate. Many business managers have already chosen ETT for different air treatment applications in shopping centres:

  • Fresh air treatment to guarantee your customers a pleasant shopping experience
  • Fresh air modulation according to CO2 level
  • Air heating and/or air cooling
  • Dehumidification of specific areas of your shopping centre (fresh produce areas)
  • Energy recovery on food refrigeration for optimised energy consumption

For brand directors in the Retail sector, total cost is essential

The purchase of an air conditioning solution is only a small part of the total cost of an operating system. A survey of our various brands indicated that energy consumption accounts for more than 70% of the total cost. Brand directors, store managers and maintenance technicians for air conditioning units need to be sure of the energy performance of the rooftop units on their building. Our commitment is to provide the right solution to optimise installations energy efficiency to its maximum according to your project specificities. Careful maintenance of ETT air conditioning units helps maximise their energy performance and lifetime. Our HVAC and dehumidification systems are covered by a 5-year guarantee, parts, labour and travel (for metropolitan France only). Our HVAC and dehumidification systems are covered by a guarantee on parts, labour and travel (for metropolitan France only).
