An LG Inverter Scroll Chiller is placed on a rooftop with a clear sky and soft sunlight in the background.
LG Air-cooled Screw Chiller is equipped with a Black Fin Heat Exchanger. The Black Fin consists of complex resin and is applied for strong protection in corrosive environments. It also offers the Blygold coating option for longer life span.

* Additional Blygold Coating Option is available for more enhanced corrosion resistance.
Unlike flooded evaporators, falling film types drip refrigerant from distributors over stacked tubes, providing direct contact with each tube for greater efficiency with less refrigerant.
The LG Air-cooled Screw Chiller offers continuous operation through an automatic emergency backup if an issue occurs in one compressor or cycle. This enhances system reliability and provides stable performance.
During high-speed rotation of the compressor, the supplied oil is recovered through a three-stage separation system. The three-stage oil recovery system minimizes the amount of oil during refrigerant circulation, improving cooling efficiency. Continuous oil supply and recovery prevents oil shortage.
* Back Up Operation function is available for over 2 compressor models.
The Air-cooled Screw Chiller utilizes installation area efficiently and features a reduced weight design.
The 15” large touched screen has improved visibility, operability. Also it supports various functions such as run history, information, scheduling, and report functions. 1)
