LG Unveils Highefficiency Watercooled Screw Chiller with Smart Tech

Data centers, industrial facilities, and commercial complexes facing extreme heat conditions require cooling solutions that ensure uninterrupted operation while maintaining comfortable working environments. LG's water-cooled screw chiller series addresses these challenges through high-performance technology, operational reliability, and intelligent control systems.

The LG water-cooled screw chiller represents a high-efficiency refrigeration solution designed for demanding cooling applications. Its compact architecture incorporates advanced screw compressors and multiple reliability features to maintain stable performance across diverse operating conditions.

• Falling Film Evaporator: Unlike conventional flooded evaporators, LG's design distributes refrigerant evenly across tube surfaces, enhancing heat transfer while reducing refrigerant charge requirements.
• Three-Stage Oil Separation: This system minimizes lubricant circulation within the refrigerant circuit, improving heat exchange efficiency while preventing compressor oil starvation.

The chiller's redundant design automatically activates backup compressors or circuits during component failures, preventing operational disruptions in critical environments.

A 15-inch touchscreen interface provides comprehensive system monitoring, including operational history, scheduling functions, and diagnostic reporting through an intuitive control panel.

• Heat Pump Capability: Optional heating functionality enables year-round operation for both cooling and heating requirements.
• Ice Storage Compatibility: Models equipped for thermal energy storage leverage off-peak electricity rates to produce ice for daytime cooling demand.

Cooling capacity ranges: 90–350 USRT (50Hz), 60–410 USRT (60Hz)

Cooling capacity ranges: 50–230 USRT (50Hz), 70–290 USRT (60Hz)

Capacity ranges: 340–1,350 USRT (50Hz), 310–1,630 USRT (60Hz)

High-efficiency screw compressors feature optimized designs for improved performance and reduced noise emissions. Select models incorporate variable frequency drives for load-matching efficiency.

Enhanced surface treatment on heat transfer tubes increases effective area while optimized flow paths minimize pressure losses across the heat exchange system.

Adaptive algorithms continuously adjust operational parameters, while remote monitoring capabilities enable off-site system management and diagnostics.

Multiple protective measures safeguard against overloading, abnormal pressures, phase failures, and other operational anomalies, complemented by automated fault detection protocols.

These chillers serve various commercial and industrial settings including office buildings, retail complexes, healthcare facilities, manufacturing plants, data center cooling systems, and district cooling networks.
