Improved part load efficiency

It is possible to precisely control up to 0.1Hz by adjusting the number of rotations through frequency control according to the load. Precision control improves the part load efficiency by 51% compared to the two-stage model running at a fixed speed, saving energy and cost.

*25% part load, based on 500RT unit in ARHI condition.

Magnetic bearing

The non-contacting magnetic bearing technology has improved lubrication loss and enhanced energy efficiency. moreover, online UPS is installed to provide emergency power during sudden blackouts in order to maintain the rotation of rotary shaft and protect bearing to operate stably.

Air bearing

LG’s exclusive air bearing technology reduces friction loss and improves overall efficiency. because it is technologically advanced, air bearing technology is applied in various industries such as industrial and aircraft applications.

Simplified piping

Oil-free chiller has simplified the piping structure by eliminating oil-related parts. There is no need to replace oil or filters, so users can save time and money at the same time.

Low-noise

By simplifying the structure of compressor and eliminating the cause of the noise, it can be applied to areas requiring low vibration and low noise by reducing noise up to 73dB(A).

*The above level indicate the noise values under the optimum operating conditions and may vary depending on the operating and environmental conditions.
