NEROMAX HT

Water-based system

The NEROMAX HT is a thermodynamic system for producing hot water.

Commercial, industrial, tertiary and accommodation buildings are major consumers of energy and therefore have a significant impact on CO_² emissions.

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

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

Description

The Neromax range is one of the solutions available for decarbonising heat production.

Thanks to its full aluminium structure (frame & casing) that ensures an excellent corrosion protection, this air conditioning and heating system is covered by a 20-year guarantee against corrosion (frame and casing).

Thanks to its full aluminium structure (frame & casing), the NEROMAX HT unit is covered by a 20-year anti-corrosion warranty.

This rooftop comes with a 5-year basic warranty and all ETT services: Commissioning, Audits, Service contracts etc.
