ULTI+ R32 ADIA OR

Air handling Heat pump Rooftop

ULTI+ R32 ADIA OR is a single flow, loop heat pump with adiabatic cooling designed for ventilating, heating and air conditioning large spaces, including medium and large shopping centres and warehouses.
This self-contained rooftop unit combines the very latest technological advances to ensure lower energy consumption. Its performance and ease of installation make it a modular solution that adjusts its performance to its environment (renovation or new construction).

The ULTI+ R32 ADIA OR is a rooftop unit using R32, a transitional refrigerant with a GWP of 675, replacing the R410A refrigerant with a GWP of 2088.

Performance (according to EN 14511 standard)

Flow range: 2 600 – 38 000 m3 /h

Cooling capacity range: 48 - 177Kw

Description

The ULTI+ R32 ADIA OR 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 performance, control and new-generation connected components, enabling the units to operate at optimum efficiency 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.
In hot weather, the high-efficiency adiabatic function takes priority over compressor activation. Thanks to specific regulation (artificial intelligence), cooling periods by evaporation are by far the majority, which means we can benefit from the environmental and economic advantages of water as a refrigerant.

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