Aurax Natural i 29.1–370.3 —
High-efficiency inverter air-water heat pump with natural R290 refrigerant
29,4–376,3 kW
Natural refrigerant,
sustainable performance
AIC presents the new Aurax Natural i our inverter reversible air-water heat pump, perfect for large commercial, industrial or centralised plantroom residential applications when you are looking for a sustainable and high efficiency solution. Aurax Natural i uses R290 refrigerant, a natural gas with a very low global warming potential (GWP) value of 3. This heat pump has a far lower environmental impact than other models on the market using different refrigerants.
The Aurax Natural i boasts an efficiency rating energy A++. The range is the perfect solution for heating, cooling and the production of domestic hot water from a single unit. Optimised for maximum efficiency in heating mode, it can operate at external temperatures down to -30 °C and has hot water production capabilities up to 60 °C. In cooling mode it can reach an outlet water temperature of up to 5 °C, with external temperature up to 50 °C.
The new AIC Aurax Natural i range is available in 11 models with a heating power range from 29,4 to 367,3 kW and cooling power from 23,4 to 312,3 kW. Furthermore, the units are fully customisable with various configuration options and can be cascaded up to a maximum of 6 units. The Aurax Natural i series adapts to different system needs and meets the requirements for tax deductions for the costs of energy re-qualification of the existing building stock.

Efficient Operation
with Reliable Heating
and Cooling
In the standard 2-pipe configuration, Aurax Natural i produces hot water for heating in winter and chilled water for cooling in summer. Domestic hot water can also be generated in priority mode with the addition of an external three-way valve.
Antifreeze protection automatically activates the circulation pump when outside temperatures fall below a programmable threshold, ensuring safe operation in colder climates.

Inverter technology — Smart modulation
for energy savings and comfort
Aurax Natural i stands out thanks to its full inverter technology, which continuously modulates the power output to match the real thermal demand of the building. Unlike traditional on/off heat pumps, it operates smoothly across different loads, maintaining stable performance and reducing electricity consumption.
By precisely adapting its capacity, the inverter system ensures higher seasonal efficiency, lower running costs, and greater comfort, while also extending the unit’s lifespan. This makes Aurax Natural i one of the most efficient and reliable heat pumps for sustainable heating and cooling.

Smart 4-Pipe Flexibility
with Free DHW Recovery
With the optional 4-pipe configuration, the unit gains a dedicated DHW circuit for all-year-round hot water production. This setup not only supplies heating and cooling but also recovers waste heat from the condenser during cooling cycles to provide free hot water.
Such efficiency makes it especially suitable for facilities like hospitals, hotels, sports centers, and industrial kitchens, where cooling and DHW demand occur simultaneously.
R290 — the advantages of propane
For the Aurax Natural i range, AIC has chosen R290 gas (propane), considered the ecological refrigerant par excellence, so much so that heat pumps that use propane as a refrigerant are not affected by the F-Gas Regulation.
The global warming potential of R290 gas is only 3 GWP, significantly lower than all traditional and new generation refrigerants.
The low GWP is also combined with an ODP of zero, a factor also highly appreciated in an era in which the choice of refrigerants is oriented towards those that do not cause damage to the environment.
Natural availability of propane is an significant advantage as it does not require additional synthesis processes for its production.
R290 propane is a safe and environmentally friendly refrigerant for heat pumps. However, it is essential to follow safety guidelines, take appropriate preventive measures and comply with current regulations to ensure safe and efficient installation and use.
