ULTI+ R32

Air treatment Heat pump RoofTop

In compliance with the ErP 2021 Directive, the ULTI+ R32 is a single-flow heat pump designed for ventilation, heating, and air conditioning of large volumes, including medium and large commercial spaces 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).

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

The ULTI+ R32 is a rooftop using R32, a low GWP refrigerant. Using this fluid minimises the impact on the greenhouse effect.

Performance (according to EN 14511 standard)

Flow range: 2,600 – 54,000 m3 /h

Cooling capacity range: 20 - 273 kW

SEER range: 4.48 – 6.29

SCOP range: 3.37 – 4.72

Description

The ULTI+ R32 belongs to the ULTIMA Green Line, a modular range of next-generation rooftops from ETT. It combines quality materials, performance, energy savings, acoustic performance, regulation, and next-generation connected components that enable the units to operate constantly in an optimal manner by transferring technical data from the machines to an external server to allow for optimal remote regulation with myETTvision (a monitoring platform that allows you to control and optimize your installation remotely).

Manufactured using an all-aluminium structure (frame and casing) for particularly effective corrosion resistance, this air conditioning and heating system comes with a 20-year anti-corrosion guarantee (frame- 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 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 basic warranty and ETT services: Commissioning, Audits, Service contracts etc.: Please consult us!
