Additionally, this unit features a U-tube structure, allowing for maintenance by removing the tube bundle (heat transfer core). 【Advantages of the Heat Exchange Business】 ■ Top-class share of shell-and-tube heat exchangers for domestic marine applications ■ Compliance with ship classification standards in various countries for marine applications ■ Factory certified under the Electric Utility Industry Law "Private Product Certification" ■ Over 2,000 units produced annually ■ Factory with ASME U certification ■ Extensive track record for power plants *For more details, please refer to the PDF materials or feel free to contact us.

The "Air Extractor" is a proven heat exchanger for power generation facilities such as waste incineration plants. It also supports unitization that incorporates connection piping, operating valves, and instrumentation piping, flexibly accommodating requests such as adjusting the handle's operating direction and arranging instruments on the control panel. Additionally, maintenance is easier compared to vacuum pump types. 【Advantages of the Heat Exchange Business】 ■ Top-class share of shell-and-tube heat exchangers for domestic marine applications ■ Compliance with ship classification requirements in various countries for marine applications ■ Factory certified for "Private Product Certification" under the Electric Utility Industry Law ■ Annual production record of over 2,000 units ■ Factory certified with ASME U certification ■ Extensive track record for power plants *For more details, please refer to the PDF document or feel free to contact us.

The "Grand Steam Condenser" is a proven heat exchanger for power generation facilities. An exhaust fan is installed at the top of the body to draw in steam that has leaked from the turbine land into the equipment. There is also a record of installing two fans on one side as a backup, and measures have been taken to mitigate fan vibrations on the frame. Designs can accommodate cooling pipes made of different materials to suit customer applications. 【Advantages of the Heat Exchange Business】 ■ Top-class share of shell-and-tube type heat exchangers for domestic marine use ■ Compliance with ship classification inspections in various countries for marine applications ■ Factory certified for "Private Product Certification" under the Electric Utility Industry Law ■ Over 2,000 units produced annually ■ Factory certified with ASME U certification ■ Extensive track record for power plants *For more details, please refer to the PDF materials or feel free to contact us.

The "Drain Cooler" is a heat exchanger that has a proven track record for ships, designed to condense and cool steam and drain water. It uses seawater or circulating water as the cooling medium and processes the drain water used in various heaters that utilize steam, as well as the surplus steam generated by exhaust gas economizers. The condensed and cooled water is reused as boiler feedwater. 【Advantages of the Heat Exchange Business】 ■ Top-class share of shell-and-tube heat exchangers for domestic marine applications ■ Compliance with ship classification standards in various countries for marine applications ■ Factory certified under the Electric Utility Industry Act "Private Product Certification" ■ Annual production record of over 2,000 units ■ Factory certified with ASME U certification ■ Extensive track record for power plants *For more details, please refer to the PDF document or feel free to contact us.

The "e-DRAIN" is a drain cooler that can adjust the drain outlet temperature. By introducing the drain into the cascade tank at the temperature set by the drain cooler, it is possible to maintain the supply water temperature at the set value without wasting energy. Maintaining the supply water temperature at the set value is also expected to be effective in preventing low-temperature corrosion. Additionally, since the drain is introduced into the cascade tank at the planned temperature, the boiler efficiency improves. 【Advantages of the Heat Exchange Business】 - Top-class share of shell-and-tube heat exchangers for domestic marine applications - Compliance with ship classification standards for marine applications in various countries - Factory certified under the Electric Utility Industry Law "Private Product Certification" - Annual production record of over 2,000 units - Factory with ASME U certification - Extensive track record for power plants *For more details, please refer to the PDF materials or feel free to contact us.
