MTA (Trane Technologies) Adds R290 Chillers GEMINI N and Aries N Deep Freezing to Its Lineup

MTA, part of Trane Technologies, has expanded its R290 propane chiller portfolio with two new series: modular air-cooled GEMINI N for comfort and process cooling, and packaged Aries N Deep Freezing (ASN DF) for low-temperature applications. The new units cover a range from commercial buildings and industrial processes to deep freezing.

GEMINI N: Modular Cooling up to 750 kW

The GEMINI N series is equipped with inverter scroll compressors. The nominal cooling capacity of a single unit ranges from 64 to 125 kW; up to six modules can be installed side by side, providing a total capacity of up to 750 kW. The chilled water temperature ranges from 25 to −12 °C.

Energy efficiency: average SEER is 5.4 in comfort cooling mode, and average SEPR HT for process cooling is 5.9. The series is offered in four acoustic configurations, with optional hydraulic modules and a built-in ATEX safety package (leak detection, common emergency shutdown). Control is managed by the Trane Symbio 800 controller with BACnet IP and Modbus TCP support.

Aries N Deep Freezing: Packaged Solution down to −30 °C

Aries N DF is designed for the food industry, cold storage warehouses, and pharmaceutical and chemical manufacturing. Seven sizes with one or two refrigeration circuits provide capacity up to 360 kW. Each circuit includes a screw compressor with a variable frequency drive, microchannel condensers, and brazed plate evaporators.

Operating parameters: outlet liquid temperature from −12 to −30 °C, ambient air temperature from −20 to +46 °C. The series complies with SEPR-LT. The package includes the SDS2E safety system: isolated compartment, leak detector, shutdown, alarm, and gas extraction fan.

MTA positions Aries N DF as an alternative to individually engineered low-temperature systems using NH3 or CO2.
