LG Expands Availability of Next-Gen Air-Cooled Inverter Scroll Chiller with R-32
LG Electronics is expanding the global availability of its latest air-cooled Inverter Scroll Chiller, a next-generation HVAC solution that supports the worldwide shift toward low-Global Warming Potential (GWP) refrigerants and sustainable technologies. The new model adopts R-32 refrigerant, which has a GWP approximately 70% lower than R-410A.
Designed as an inverter-driven heat pump system, the chiller delivers both chilled and hot water, making it suitable for mid-sized commercial buildings requiring reliable thermal management throughout the year.
Following initial launches in North America, Europe and South Korea, LG is continuing to expand the availability of the Inverter Scroll Chiller globally in 2025. One notable installation at Garden Grove Elementary School in Winter Haven, Florida, replaced an aging 60-ton unit with three LG Inverter Scroll Chillers. The school has since seen an 18% reduction in energy consumption along with quieter operation — also an important factor in its residential setting.
The new Inverter Scroll Chiller is designed to provide exceptional energy efficiency under a variety of operating conditions. Powered by LG’s All-Inverter compressor, which operates across a wide frequency range (30Hz to 120Hz), it offers high performance and reduced energy consumption even under partial load.
LG’s proprietary HiPOR (High Pressure Oil Return) system enhances compressor efficiency by returning oil directly into the compression chamber, significantly reducing energy loss. As a result, the unit achieves an Integrated Part Load Value (IPLV) of up to 5.9, based on ANSI/AHRI Standard 551/591. Select models also feature heat exchangers optimized for a broad water outlet temperature range, from 14° F to 140° F, offering flexibility for diverse applications.
The chiller is built to support dependable performance across various seasons and climates. With twin All-Inverter compressors and vapor injection technology, the system maintains stable heating capacity even in extreme cold, modulating down to 20% load. In high ambient conditions, a refrigerant-cooled heat sink helps maintain operation at up to 126° F, offering a potential advantage over conventional air-cooled systems.`
To support uninterrupted operation under demanding conditions, the system includes features such as compressor backup, intelligent control logic and sequential defrost. It also supports hot water output up to 140° F, helping suppress Legionella bacteria growth and contributing to hygienic operation in facilities such as spas, hotels and hospitals. For added durability in coastal or humid regions, the heat exchanger is treated with LG’s corrosion-resistant Black Fin coating.
An integrated energy-saving algorithm helps reduce power consumption by up to 10% while an auto-recovery feature restores previous settings after a power outage to help minimize downtime. Features such as compressor backup and sequential defrost contribute to continuous operation during maintenance. The chiller also operates at a low noise level of 68dB, with a Silent Operation mode available for quieter performance during off-peak hours.
