Automatic anti-crystallization safety operationReliability

Intelligent system prevents the crystallization of absorbent through a safety-control logic algorithm.

LG’s LiBr-water solution function enables uninterrupted system monitoring, resulting in the following benefits:

  • The LiBr-water solution’s concentration level is maintained at an optimum level, thereby preventing crystallization.
  • The chiller uses sensors to detect the status of absorbent and controls temperature distribution by adjusting combustion levels.



Each heat exchanger piping connection has been simplified and strengthened in order to maintain an optimal vacuum state, thereby minimizing potential leakage points.




The microprocessor also has a self-diagnosis function, capable of alerting system managers to any potential issue; preventing inefficient operation and averting inconvenient breakdown.




High Part Load EfficiencyWith HVAC solutions operating at less than full capacity the majority of the time, efficiency in part-load is essential. LG’s absorption chiller achieves energy savings and increased part-load efficiency via an advanced absorbent pump featuring state-of-the-art inverter control. The optimized system also decreases capacity in accordance with the volume of absorbent in circulation.
