ULTI+ R32 RE

Air treatment Heat pump 4-damper system

Compliant with the ErP 2021 directive, the ULTI+ R32 RE is a double flow heat pump designed specifically for the ventilation, heating and cooling of rooms with variable occupancy, such as auditoriums and multipurpose rooms. These double flow heat pumps include various pieces of equipment for optimised energy use.

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

Discover our latest generation rooftop unit featuring an almost negligible impact on global warming: ULTI+ R290 with a GWP of 0.02.

Description

The ULTI+ R32 RE double-flow heat pump using the low GWP R32 refrigerant is specifically designed for ventilation, heating and air conditioning of spaces with variable occupancy, such as, performance halls and community halls. This self-contained unit features specific components to maximise energy savings.

 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 RE 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.
