The "StirLNG-4" is an independently operating ultra-low temperature liquefaction device powered by an electric motor and a unique control unit. LNG is extracted from the bottom of its storage tank and, after additional cooling, is sprayed back into the storage tank to lower the overall gas pressure of the system while removing BOG. The composition of LNG or BOG does not affect the cooling capacity of this product. 【Features】 ■ Supports small-scale production of liquefied natural gas (LNG) from refined gas sources such as pipelines and biogas. ■ Re-liquefies BOG generated within ultra-low temperature devices (fuel stations, storage tanks, etc.) without loss. ■ Re-liquefies BOG from LNG tanks on vessels. *For more details, please refer to the PDF materials or feel free to contact us.

The "StirLNG-4" is a cryogenic liquefaction device specially modified for small-capacity LNG re-liquefaction for ships. It operates with an electric motor and is equipped with a unique control unit for independent operation. BOG can be extracted from the storage LNG tank, cooled in the heat exchanger of this device, re-liquefied, and returned to the storage LNG tank. 【Features】 ■ Supports small-scale production of liquefied natural gas (LNG) from refined gas sources such as pipelines and biogas. ■ Re-liquefies BOG generated within cryogenic devices (fuel stations, storage tanks, etc.) without loss. ■ Re-liquefies BOG from LNG tanks on ships. *For more details, please refer to the PDF document or feel free to contact us.

The "CryoFan Series" is a blower fan manufactured and optimized to efficiently transfer cold heat by circulating ultra-low temperature gas. The pump is of a spiral type, allowing for the circulation of gas (often helium or nitrogen) to connect the cooling device and the cryo cooler for the transfer of cold heat. With the connection for cold heat transfer, the cryo cooler can be installed at an appropriate distance from the cooling device. 【Features】 ■ Blower fan manufactured and optimized for efficient cold heat transfer ■ Spiral type pump ■ Easy integration with cryostats *For more details, please refer to the PDF materials or feel free to contact us.

In the petrochemical industry, a stable supply of raw materials is key to business continuity. In particular, when using LNG as a raw material, the generation of BOG (Boil-Off Gas) poses a significant challenge that reduces supply efficiency. The occurrence of BOG leads to losses of LNG and increases costs. StirLNG-4 enables the re-liquefaction of this BOG and returns it to the LNG tank, allowing for effective utilization of raw materials. This contributes to stable raw material supply and cost reduction. 【Usage Scenarios】 - LNG plants - LNG storage tanks - LNG transport ships 【Benefits of Implementation】 - Reduction of BOG losses - Effective utilization of LNG - Stabilization of raw material supply

In the low-temperature transportation industry for food, temperature management during transport is key to maintaining quality. Particularly for frozen and refrigerated foods, it is crucial to maintain a stable low-temperature environment to prevent quality degradation and food loss due to temperature fluctuations. Low-temperature transportation using LNG (liquefied natural gas) contributes to reducing fuel costs and environmental impact, but the generation of BOG (Boil-Off Gas) poses a challenge. StirLNG-4 re-liquefies BOG and maintains a constant pressure within the LNG tank, thereby preserving food quality and improving transportation efficiency. 【Usage Scenarios】 - Maritime transportation of frozen and refrigerated foods - LNG supply to low-temperature logistics warehouses - Food transportation using LNG-fueled vessels 【Benefits of Implementation】 - Reduces BOG losses and improves LNG utilization efficiency - Provides a stable low-temperature environment to maintain food quality - Contributes to reducing fuel costs and environmental impact

In the power industry, especially in distributed energy sources, a stable energy supply is essential. In power generation systems using LNG as fuel, the generation of BOG (boil-off gas) poses a challenge. BOG is the evaporated gas from stored LNG tanks and can lead to energy loss and safety issues. StirLNG-4 contributes to improving energy efficiency and ensuring safety by re-liquefying this BOG and returning it to the LNG tank. 【Usage Scenarios】 - Distributed power plants using LNG as fuel - Emergency power supply systems - Stabilization of power supply 【Effects of Implementation】 - Reduction of energy loss due to BOG - Improvement of safety in LNG storage tanks - Cost reduction through effective utilization of LNG

In the fishing industry, reducing fuel costs for fishing vessels is an important challenge. As the adoption of LNG-fueled ships progresses, the management of BOG (boil-off gas) generated in LNG tanks has become a crucial factor affecting fuel efficiency. If BOG is not properly managed, it leads to fuel waste and contributes to increased operating costs. StirLNG-4 enables the re-liquefaction of BOG generated in the LNG tanks of fishing vessels, allowing it to be reused as fuel. This helps reduce fuel waste and contributes to lowering operating costs. 【Usage Scenarios】 - Fishing vessels using LNG fuel - Re-liquefaction of BOG in fishing vessel LNG tanks - Stakeholders in the fishing industry aiming to reduce fuel costs 【Benefits of Implementation】 - Fuel cost reduction through BOG re-liquefaction - Efficient use of LNG fuel - Reduction of environmental impact

In the cruise ship industry, as the introduction of LNG-fueled vessels progresses, the generation and management of BOG (Boil-Off Gas) has become an important issue. BOG is generated by the natural evaporation from LNG tanks and can lead to fuel loss and safety concerns. StirLNG-4 helps reduce fuel waste and supports safe operations by re-liquefying this BOG and returning it to the LNG tank. 【Usage Scenarios】 - Cruise ships using LNG fuel - Vessels that want to suppress BOG generation from LNG tanks 【Benefits of Implementation】 - Reduction in fuel costs - Improved safety - Decreased environmental impact
