ULTI+ R32 OR

Air handling Heat pump Rooftop

ULTI+ R32 OR is a single-flow, water-loop heat pump designed for ventilating, heating and air conditioning large spaces, including medium and large shopping centres and warehouses. This rooftop unit combines the latest technological developments to ensure optimised 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 OR is a rooftop using R32, a low GWP refrigerant.

Performance (according to EN 14511 standard)

Flow range: 2,600 – 38,000 m3 /h

Cooling capacity range: 48 - 177Kw

Description

ULTIMA Green Line is ETT’s latest-generation modular rooftop range. It combines quality materials, performance, energy savings, acoustics, regulation and new-generation connected components to ensure that the units operate at optimum efficiency at all times.

An unrivalled product range (flow rates/power) that perfectly meets the weight and space constraints of existing units to be replaced.

The modular design allows for easy expansion of this range’s capacities. Users can choose to install the standard ULTI+ R32 heat pump, or add modules (condensing boiler(s), extract unit, extract unit with rotary energy recovery, dehumidifier, adiabatic module, OR [water-air] module) to this single-block unit in order to adjust the unit’s performance to the environment and the requirements of the application.

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