Air cooled chillers & heat pumps
EUROVENT Certified - Made in Italy
RHOSS a conscious choice
Behind every RHOSS chiller there is over 52 years experience, backed up by one of the largest EUROVENT Research and Development centres in Europe.
The air cooled range has been developed to achieve the highest efficiency covering a capacity scope starting at 5 kW up 1.6 MW (EUROVENT conditions).
RHOSS chillers and heat pumps have built an enviable reputation for quality, low noise levels, corrosion resistance and high efficiency.

The low consumption technology (Predictive)
Adaptive Function Plus is an innovative predictive control software, patented in exclusive by RHOSS, developed with the collaboration of the Departments of Technical Physics and Computer Engineering of the University of Padua.
The new logic allows the chiller to collect information from the system regarding its load and inertia, and to adjust and optimize the operating parameters in order to reduce the energy consumption of chillers and heat pumps.
The energy requiered, only when requiered
In the air conditioning systems, the chillers only operate at full load for a small number of hours while they work at partial load for most of the season: therefore they must be designed and managed in a way that their energy consumption is as low as possible during the entire period of use.
Adaptive Function Plus works on the set-point value, allowing to increase the unit efficiency and to reduce the energy consumption, compared to chillers and heat pumps of the same capacity and with traditional control logic.
The energy consumption saving reaches 36% in the winter and 18% in the summer!
RHOSS is a company specialised in the design and manufacture of products and systems for air conditioning and air handling.
Founded in 1968, it immediately became the leader in the sector of steel boilers for domestic heating.
It entered the world of air-conditioning in 1971 with the production of fan coils and subsequently with cooling units.
For more than 50 years, RHOSS has been a guarantee for innovation, quality and top level service. This is what makes us an ideal partner for HVAC (Heating, Ventilation and Air Conditioning) system specialists.
RHOSS growth and development is an evolution that combines investments and projects in order to make the company a point of reference also for international markets.
Our renewal has followed market development and customer needs, in particular offering highly efficient products and systems that are in line with the requirements of the most modern Green Buildings.
