ULTI+ R32 ADIA

Air treatment Heat pump Rooftop

ErP 2021 compliant, the ULTI+ R32 ADIA is a single flow heat pump with adiabatic cooling designed for the ventilation, heating and air conditioning of large volumes, including medium and large commercial stores and warehouses. This stand-alone rooftop unit combines the latest technological developments to ensure lower energy consumption. Its performance and ease of installation make it a modular solution that effectively adapts to its environment (renovation or new).

The ULTI+ R32 ADIA is a rooftop with R32, a low GWP refrigerant.

Performance (according to EN 14511 standard)

Flow range: 6 000 - 38 000 m3 /h

Cooling capacity range: 44 - 190 kW

Description

The ULTI+ R32 ADIA is an evolution of ETT’s latest generation rooftop range. It has been developed on the basis of the EUROVENT-certified ULTI+ R32 range, and is the subject of a patent application. It combines quality materials, , energy savings, acoustic peformance, regulation and next-generation connected components, to allowing the units to operate optimally at all times. The combination of thermodynamic and direct adiabatic technologies means that energy consumption is kept to a minimum, while ensuring that indoor comfort requirements are met at all times, whatever the climatic conditions outside.

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 single flow rooftop heat pump is delivered ready to operate. A separate technical compartment facilitates unit control and maintenance and allows measurement and adjustment during operation.

The ULTI+ R32 ADIA is designed to provide precise regulation, adapting the rotational speeds of the power stages, for optimum, continuous energy performance throughout its years of operation.

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