Air-cooled liquid chillers with scroll compressors and R290 refrigerant gas.
Nominal cooling capacity 165 – 240 kW
High Performance and Sustainability in One Versatile Solution
Designed to deliver unmatched energy efficiency across both Comfort and Process Cooling applications, this unit offers exceptional versatility thanks to its wide operating map, with leaving water temperatures ranging from -12 °C to +25 °C. Its all-in-one configuration—with optional integrated hydraulic kits and partial heat recovery—makes it a flexible solution for a broad range of needs. The optimized refrigeration circuit features scroll compressors in tandemXtrio configurations across two independent circuits, combined with micro-channel condenser coils and a brazed plate evaporator, ensuring top-level performance. Advanced control is provided by the latest Trane Symbio™ 800 adaptive controller, allowing precise and intelligent system management. Sustainability is at the core, with the use of R290 refrigerant—non-ozone-depleting and boasting an ultra-low Global Warming Potential (GWP).

Versatile Air-Cooled Chillers for Extreme Climates
ARIES N ASN air-cooled chillers are built to ensure reliable and energy-efficient performance all year round, even in the most challenging weather conditions. Designed to operate effectively across a broad outdoor air temperature spectrum — from -20 °C up to +48 °C — they offer full-load functionality in both cold and hot environments. Thanks to a wide leaving water temperature range between -12 °C and +25 °C, these chillers are perfectly suited for a wide range of uses, from traditional comfort cooling to high-performance industrial process cooling.
Consistent Energy Efficiency Across All Operating Conditions
ARIES N ASN chillers are engineered to maintain high performance and energy efficiency in any scenario. At full load, they achieve an average Energy Efficiency Ratio (EER) exceeding 3.4. In process cooling scenarios, they deliver a Seasonal Energy Performance Ratio for High Temperature (SEPR HT) above 6.4 — ensuring excellent results even in variable load conditions.
Recover Heat and Improve Overall System Efficiency
With the optional Partial Heat Recovery feature, ARIES N ASN units can repurpose waste heat to generate hot water, boosting overall sustainability. This is achieved via an additional brazed plate heat exchanger, thermally insulated to minimize energy loss. The system is designed with maintenance in mind, including external access to the water-side connections, an upper air vent, and a lower drainage valve for easy servicing.
Designed with Built-In Safety Features
Safety is embedded into every detail of the ARIES N ASN. The refrigeration components are isolated in a dedicated section equipped with an ATEX-approved leak detection system, which automatically disconnects the main loads and activates certified extraction fans in case of gas leakage. To further enhance protection, the electrical panel is physically separated from the unit, and safety valves are installed on both high- and low-pressure sides of the circuit.
