High-performance modular air-to-water heat pump for commercial applications
We are pleased to announce the launch of the Amicus Altus 112, a powerful new addition to the Amicus Altus range of air-to-water heat pumps. Designed specifically for large-scale commercial heating, cooling and hot water applications, the Amicus Altus 112 delivers outstanding performance, flexibility, and sustainability for projects where reliability and efficiency are critical.
Delivering outputs from 112 kW up to 1,120 kW per cascade, and capable of achieving water flow temperatures of up to 75 °C, the Amicus Altus 112 is ideally suited to applications such as healthcare facilities, sports and leisure centres, hotels, and renovation projects. Its modular design allows systems to be precisely sized to meet project requirements, whether for new-build or retrofit installations.
A Sustainable Solution for Decarbonising Heat
The Amicus Altus 112 uses R290 (propane), a natural refrigerant with an exceptionally low Global Warming Potential (GWP) of just 3. This makes it a highly sustainable solution for decarbonising heat without compromising on performance or operating temperatures.
As a fully electric system, the Amicus Altus 112 produces zero on-site emissions. When combined with renewable electricity or photovoltaic systems, it enables completely carbon-free operation, supporting long-term sustainability and net-zero objectives.
Designed for Flexibility and Performance
The Amicus Altus 112 has been engineered to integrate seamlessly with the existing Amicus Altus 88 kW R290 unit, allowing mixed cascades and increased system flexibility. Up to ten units can be connected in cascade, delivering a total output of up to 1,120 kW, while maintaining a compact footprint and requiring only a 2-metre exclusion zone around each unit.
Available in 2-pipe or 4-pipe configurations, the system includes flow and return header arrangements and a primary pump per unit, simplifying installation and system design.
