LG Water-cooled Screw Chiller placed in a light gray virtual space.
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 Water-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 1 Compressor model 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)
1) Depending on the model, the New Chiller Controller may not be applicable.
LG Water-cooled Screw Chiller provides various utilizing options such as heat pump, ice thermal storage. These options help provide efficient heating and cooling.
