Oil-free Centrifugal Chiller
The LG Oil-free Centrifugal Chiller operates on an oil-free system, enabling simplified piping for easy maintenance and efficient performance.
What is LG Oil-free Centrifugal Chiller
Oil-free Centrifugal Chiller
The LG Oil-free Centrifugal Chiller incorporates an oil-free system, two-stage compressor, magnetic bearing, and various LG technologies to deliver a reliable and efficient cooling solution.
Enhanced Part-Load Efficiency
Frequency control allows precise speed adjustment down to 0.1Hz, improving part-load efficiency by 51% over fixed-speed models and reducing energy and operating efficiency.1), 2)
1) Tested at 25% part load, based on Oil-free Centrifugal 500RT unit in AHRI condition.
2) It may vary depending on actual usage conditions.
