NEROMAX

Water-based system

NEROMAX is a thermodynamic system for producing hot or chilled water.

Commercial, industrial, tertiary and accommodation buildings are major consumers of energy and therefore have a significant impact on CO² emissions.

 ETT’s Research and Development department has designed an innovative high-power, very low noise reversible air-to-water heat pump solution.

This eco-responsible heat pump uses a natural fluid: propane (R290).
