Aurax Eco 25.1–710.5 —
High-efficiency reversible
air-water heat pump

21,6–708,6 kW

Efficient heating and cooling
with low environmental impact

The Aurax Eco is a high-efficiency on/off reversible air-to-water heat pump, designed to deliver reliable heating, cooling, and domestic hot water production. With outputs ranging from 25 to 710 kW, it adapts seamlessly to both small and large projects, offering year-round comfort in residential, commercial, and industrial settings. Optimized for heating, it operates down to external temperatures of –15 °C while producing hot water up to 60 °C.

All models are reversible, capable of producing chilled water for summer cooling, and equipped with a DHW circuit managed via a 3-way external valve. An optional 4 Pipe version is available for simultaneous cooling and DHW production. With its compact design, wide operating range, and use of ecological R454B refrigerant, the Aurax Eco ensures maximum efficiency, reduced environmental impact, and compliance with European incentives for sustainable heating solutions.

Reliable hot water supply
for diverse facilities

Aurax Eco product range

The Aurax Eco range covers the full spectrum of residential, commercial and industrial applications, with heating outputs from 21,6 to 708,6 kW. Three model groups make it easy to match the right unit to any project — from small homes and boutique businesses to large hotels, hospitals and industrial plants.

  • Aurax Eco 25.1–55.1

    21,6–54,1 kW

  • Aurax Eco 61.2–114.2

    57–106,.9 kW

  • Aurax Eco 150.1–330.2

    147,3–333,6 kW

  • Aurax Eco 390.3–710.5

    390–708,6 kW

Efficient Operation
with Reliable Heating
and Cooling

In the standard 2-pipe configuration, Aurax Eco 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.

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.

R454B — Next-Generation
Refrigerant for a Greener Future

The Aurax Eco range is built around R454B refrigerant, chosen for its very low Global Warming Potential (GWP 466). Compared to R410A, it reduces environmental impact by 78%, and it is also 30% lower than R32. With zero ODP and low flammability (A2L), R454B ensures safe operation and outstanding performance in both heating and cooling, supporting the transition to a more sustainable energy future.
