CTA ULTI+

Air treatment AHU (Air Handling Unit)

The CTA ULTI+ is a single-flow air treatment unit designed for ventilation, heating and air conditioning, and complies with the ERP 2018 directive. This air handling unit combines the latest technological developments to ensure optimised energy consumption. Its performance and ease of installation make it a modular solution that effectively adapts to its environment (renovation or new).

Description

The ULTIMA Green Line AHU 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 ULTIMA Greenline air handling 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 5-year basic warranty and all ETT services: Commissioning, Audits, Service contracts etc.
