World Energy’s industrial absorption chillers recover waste heat—such as steam, hot water, or exhaust gas—generated from industrial processes or surplus district heating during summer. This recovered energy is used to supply cooling and heating, significantly reducing electricity consumption and lowering carbon emissions.
These systems are widely used across various industrial facilities such as petrochemical plants, paper mills, food processing factories, and steelworks—where large amounts of waste heat are typically produced. In addition, they are also applied in large commercial buildings receiving district heating, including airports, knowledge industry centers, hotels, and general hospitals.
World Energy has also developed and exported marine absorption chillers designed specifically for ships and offshore plants. These units operate using waste heat from ship engines—such as exhaust gas, steam, or hot water—instead of electricity, and they utilize water as a natural, eco-friendly refrigerant that emits no greenhouse gases. The chillers feature corrosion-resistant designs and use seawater as cooling water, making them suitable for a wide range of cooling needs such as cabin air conditioning and onboard refrigeration.
In addition to the marine chillers, World Energy offers brine absorption chillers that can supply sub-zero chilled water for low-temperature cooling needs. While conventional absorption chillers typically use distilled water as the refrigerant and lithium bromide solution as the absorbent—making them safe and environmentally friendly—the use of water limits the chilled water temperature to around 4 °C.
World Energy’s brine absorption chillers overcome this limitation by mixing lithium bromide into the refrigerant, enabling lower evaporation temperatures. These systems can supply brine at –4 °C and, with a two-stage configuration, as low as –7 °C. As a result, they are suitable not only for HVAC applications but also for cold storage, medical facilities, and low-temperature industrial processes requiring reliable sub-zero cooling.
