MTA, part of Trane Technologies, has introduced two R290 chiller ranges: GEMINI N modular air-cooled chillers and Aries N Deep Freezing (ASN DF) packaged screw compressor chillers. The new units expand the company’s low-GWP cooling portfolio for commercial buildings, industrial processes and low-temperature applications.
GEMINI N features full-inverter scroll compressors and nominal cooling capacities from 64 to 125 kW (approximately 218,000–426,500 BTU/h). The range achieves an average SEER of 5.4 for comfort cooling and an average SEPR HT of 5.9 for process cooling. Chilled water temperatures range from 25°C (77°F) to -12°C (10.4°F).
Up to six GEMINI N units can be installed side by side, providing combined cooling capacity of up to 750 kW (approximately 2.56 million BTU/h). The range offers four acoustic versions, optional hydraulic modules and an integrated safety package featuring ATEX leak management and shared interlock shutdown. The Trane Symbio 800 controller supports BACnet IP and Modbus TCP connectivity.
The Aries N Deep Freezing range is designed for food and beverage processing, refrigerated warehouses, pharmaceutical and chemical applications. Available in seven sizes with single- or dual-circuit configurations, it delivers capacities up to 360 kW (approximately 1.23 million BTU/h). Each circuit incorporates a variable frequency drive screw compressor, alongside microchannel condensers and brazed plate heat exchanger evaporators.
Aries N operates with leaving fluid temperatures from -12°C (10.4°F) to -30°C (-22°F) and ambient temperatures from -20°C (-4°F) to +46°C (114.8°F). The SEPR-LT-compliant range includes SDS2E safety features comprising a segregation box, leak detector, stop, signal and gas expulsion fan. MTA positions the packaged system as an alternative to custom-built NH3 or CO2 installations for low-temperature industrial cooling.
