Air-cooled Screw Chiller

LG Air-cooled Screw Chiller provides a reliable and compact cooling solution with corrosion-resistant heat exchanger.

What is Air-cooled Screw Chiller

LG Air-cooled Screw Chiller shown in a virtual space with four key features summarized. LG Air-cooled Screw Chiller shown in a virtual space with four key features summarized.

Air-cooled Screw Chiller

It is coated with Black Fin technology, providing enhanced corrosion protection. Additionally, it offers convenience in installation and operation through reduced weight and efficient installation space.

Corrosion Resistance

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.

Falling Film Type

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.

Highly Reliable Technology

    Back Up Operation

    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.

  • Structural diagram illustrating the Oil Recovery System process.

    Oil Recovery System

    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.

Convenient Installation & Control
