Aurax Mini Ni 2T

High efficiency and ecological inverter reversible air-water heat pump

Aurax Mini Ni 2T

High efficiency and ecological inverter reversible air-water heat pump

The Aurax Mini Ni heat pump uses eco-friendly R290 refrigerant with a global warming potential (GWP) of just 3, offering a sustainable solution for heating, cooling, and domestic hot water production. Designed for maximum efficiency, it operates in heating mode at temperatures as low as -20°C, producing hot water up to 70°C, and in cooling mode, it delivers water at 5°C even in external temperatures of 50°C. Available in 2 and 4-pipe models with heating capacities from 9.7 to 38.9 kW and cooling capacities from 8.1 to 30.1 kW, the Aurax Mini Ni 15 also has an optional three-phase version. For greater demands, up to six units can be cascaded for enhanced performance.

Design

Aurax Mini Ni is capable of producing hot water up to 70 °C even with low external temperatures (-10 °C), making it the best solution when introducing renewable technology to existing systems which were originally created with a high temperature heating circuit.

Due to the high DHW output temperature, the Aurax Mini Ni can deliver safe domestic hot water production without the requirement of a supplementary electrical boost, which is required by other heat pumps to safeguard the system against legionella.

Key features and benefits

The Aurax Mini Ni heat pump combines eco-friendly R290 refrigerant (GWP 3) and inverter technology for high efficiency and low energy consumption.

Made in Europe by AIC, it offers year-round heating, cooling, and DHW production, quiet operation, and meets tax deduction requirements for energy re-qualification, making it a sustainable and cost-effective choice.

DHW priority programming

Aurax Mini Ni, in addition to operating in total DHW priority depending on demand, allows a maximum domestic hot water production phase to be set, after which the unit will return to producing hot water for the heating system to avoid an excessive drop in the temperature of the heated rooms and maintain building comfort.

If the DHW set point was not reached in the initial phase because it was blocked by the DHW priority programming, the heat pump will return to producing DHW after a set time. It is important to avoid excessive prolonged operation in DHW mode as this will cool the water in the heating circuit.

Aurax Mini Ni 2T Operating logic in DHW production

The 2 Pipe model starts in heating mode to maintain the temperature of a DHW tank at the established set point value.

A temperature sensor (supplied with the unit) is inserted into the DHW tank to regulate the production of hot water. This operation requires the installation of a 3-way valve (supplied as an option).

Natural refrigerant R290

R290, also known as propane, is a natural refrigerant used in various cooling and air conditioning applications. It is highly efficient and has excellent thermodynamic properties, making it an eco-friendly alternative to synthetic refrigerants.

One of its key advantages is its very low Global Warming Potential (GWP) of just 3, meaning it has a minimal impact on climate change compared to traditional refrigerants like R134a or R410a, which have significantly higher GWP values.
