X-RCAM+ R290 – New!

Air treatment Heat pump 100% fresh air

The X-RCAM+ R290 (Recovery Clean Air Management) is designed to supply hygienic fresh air at a neutral temperature, as required by regulations for public buildings: hotels, collective housing, hospitals and nursing homes, as well as office buildings.

Regulation is based on the supply air temperature.

Thanks to the various innovations and materials used, the X-RCAM+ R290 combines performance, reliability, air quality and respect for the environment.

The EU Regulation 2024/573 (also known as F-Gas III) mandates a gradual phase-out of fluorinated greenhouse gases, culminating in a complete ban by 2050..
As a result, the installation of new rooftops using refrigerants with a GWP greater than 150 will be prohibited:
* 2027 for power ratings ≤ 50 kW
* 2030 for power ratings > 50 kW

In anticipation of these regulatory changes, ETT has adapted its X-RCAM+ R290 range to use a refrigerant with an extremely low GWP.

The X-RCAM+ R290 is a dual-flow heat pump featuring a plate heat exchanger and using propane as a natural, non-fluorinated refrigerant with an almost zero GWP (0.02). This makes it a forward-looking technology in the thermodynamic dual-flow dehumidification segment, completely insulated from the impending regulatory changes.

Performance (according to EN 14511 standard)

Flow range: 3 000 – 15 000 m3/h

Cooling capacity range: 10 – 47 kW

Description

This double 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.

Thanks to its full aluminium structure(frame & casing) that ensures an excellent corrosion protection, this air conditioning system with energy recovery is covered by a 20-year guarantee against corrosion (frame and casing).

Energy recovery from exhaust air in winter and summer is carried out via a heat exchanger (PHE). The setpoint temperature can be maintained thanks to this recovery and, to the heat pump reversible cycle if required.

An adiabatic module is available as an option. It is installed upstream of the plate heat exchanger in the return air stream and helps to lower the return air temperature, thus enhancing the efficiency of the heat exchanger. The system significantly reduces the operating hours of the thermodynamic circuit during the summer months.

This rooftop comes with a 1-year basic warranty, and allETT services: Commissioning, Audits, Service contracts etc.
