The LG Ice Thermal Storage (ITS) Screw Chiller is an intelligent cooling solution designed to manage energy loads with surgical precision. Distributed by ETC Bangladesh, this system acts as a "thermal battery" for your building. Instead of running a large chiller at maximum capacity during the heat of the day when electricity tariffs and ambient temperatures are at their highest, the ITS system produces and stores ice during the cool, off-peak night hours.

Strategic Peak-Shaving & Cost Reduction

The ITS Screw Chiller is the definitive tool for "Load Shifting" in the Bangladesh industrial and commercial sectors.

Low-Cost Night Power: By operating during off-peak hours, the system takes advantage of lower nighttime electricity rates, drastically reducing the monthly energy bill for large-scale facilities.
Stable Power Management: It helps facilities cope with power grid load problems during the summer by reducing the peak daytime demand, which can also lead to lower "demand charges" from utility providers.
Infrastructure Downsizing: Because the stored ice handles a portion of the peak load, the primary chiller and the associated electrical transformers and backup generators can be sized smaller, reducing initial capital investment.

High-Efficiency Falling Film Evaporator

LG has optimized the heat exchange process by applying a Gravity-Type Falling Film Evaporator.

Superior Heat Transfer: Liquid refrigerant is distributed via gravity in a uniform film over the evaporator tubes. This ensures higher evaporation efficiency compared to standard flooded systems.
Reduced Refrigerant Charge: The falling film design requires significantly less refrigerant to achieve the same cooling effect, making it a more environmentally responsible choice.

Three-Stage Oil Recovery System

Reliability during high-speed operation is ensured by LG’s proprietary Three-Stage Oil Recovery System.

Purity & Efficiency: The system uses a multi-stage separation process to ensure that lubricant is captured and returned to the compressor before it can enter the heat exchangers. This prevents "oil fouling," which can degrade thermal efficiency over time.
Continuous Lubrication: By maintaining a constant supply and recovery of oil, the chiller prevents oil shortage and mechanical wear, even during the demanding low-temperature cycles required for ice production.

Operational Intelligence & "Black Box" Diagnosis

Quiet & Compact Design: The unit features a redesigned intake port that minimizes turbulence and noise. Its compact structure is optimized for space-constrained mechanical rooms, offering more RT (Refrigeration Tons) per square foot.
Black Box Feature: The integrated "Black Box" records and analyzes operational data. In the event of a system fault, the ETC Bangladesh team can access this record for an instant diagnosis, significantly reducing troubleshooting time.
Smart Central Control: Fully compatible with LG’s ACP and AC Smart platforms, allowing for remote monitoring of ice levels, thermal tank temperatures, and overall plant efficiency through a web-based dashboard or smartphone.
