CTA ULTI+ ADIA CC+

Air handling AHU

The ULTI+ ADIA CC+ consists of a single-flow air handling unit with condensing boiler(s) fitted with an adiabatic cooling system that allows the machine’s performance to be adjusted to the environment.

This unit meets the needs of your renovation or new-build projects.

Description

The CTA ULTI+ ADIA CC+ unit is ETT’s new modular range of latest-generation AHUs. It combines quality materials, acoustic performance, energy savings, regulation and new-generation connected components, enabling the units to operate at optimum efficiency at all times.

For a floor installation, the CTA ULTI+ ADIA CC+ unit is delivered with its support feet. However, the special feature of this unit is that it can also be installed on a curb with air supply and return from below through the roof.

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).

This rooftop comes with a 1-year basic warranty and all ETT services: Commissioning, Audits, Service contracts etc.
