The First R290 Rooftop Unit is French!

Always at the cutting edge of innovation, ETT takes a new step forward by introducing the R290 natural refrigerant to its “ULTIMA Green Line” rooftop range. R290 boasts an almost zero global warming potential (GWP = 0.02).

🌿 A Sustainable Technological Choice

Designed to support our clients’ environmental transition, this R290 version:

  • Dramatically reduces the carbon footprint of installations,
  • Fully meets the requirements of F-Gas III regulation which mandates the gradual phase-out of fluorinated greenhouse gases,
  • Prepares for upcoming HFC usage restrictions scheduled for 2027 and 2030.

🔧 Premium-Quality Design
As with all ETT products, this solution is made in Brittany and features exceptional corrosion resistance, thanks to a fully aluminium frame and casing — backed by a 20-year warranty

✅ A Reliable, Efficient, and Responsible Solution

Offered with a full 5-year warranty across mainland France, plus all ETT services: commissioning, DESP certification, audits, and service contracts. etc.
