ULTI+ R32 RE

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.
