LG expands availability of R32 chiller
21st July 2025
SOUTH KOREA: LG Electronics is expanding the global availability of its latest R32 air-cooled inverter scroll heat pump chiller.
Launched last year in North America, Europe and South Korea, the new model delivers both chilled and hot water, making it suitable for mid-sized commercial buildings requiring reliable thermal management throughout the year.
Powered by LG’s All-Inverter compressor, which operates across a wide frequency range (30Hz to 120Hz), it is said to offer 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 IPLV of up to 5.9.1.
Select models also feature heat exchangers optimised for a broad water outlet temperature range, from -10ºC to 60ºC.
With twin All-Inverter compressors and vapour injection technology, the system is said to maintain 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 52ºC, 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.
For added durability in coastal or humid regions, the heat exchanger is treated with LG’s corrosion-resistant black fin coating.
The chiller supports adaptable control options based on project size.
Small installations can use an intuitive 5in HMI touch panel for on-site control, with remote installation supported up to 500m.
Mid-sized projects benefit from LG’s ACP and AC Smart controllers, which support up to 10 units with features such as scheduling, input/output linkage and error tracking.
Larger applications are supported by the LG Building Energy Control (BECON) CPM platform, which can coordinate up to 30 chillers and manage auxiliary devices like pumps, valves and sensors to improve overall system efficiency.
The chiller also operates at a low noise level of 68dB, with a Silent Operation mode available for quieter performance during off-peak hours.
