Heat recovery

The "TR Series" recovers and effectively utilizes up to 92% of exhaust thermal energy

The hot water recovery unit captures and effectively utilizes thermal energy that would otherwise be lost through cooling towers and other means. By recovering up to 92% of exhausted thermal energy, it enhances overall factory energy efficiency, reduces electricity and gas costs, and lowers CO₂ emissions. The recovered thermal energy can be repurposed for various applications, including heating boiler feedwater, powering heaters, showers, and thermal water pools.


Product features
・Hot water recovery for water-cooled oil-free compressors
・Recovers up to 92% of exhausted thermal energy
・Recycles thermal energy as a heat source
・Recovers heat from the gas cooler, oil cooler, and compressor body by modifying cooling water lines
・Exceptionally quiet operation
・For a 250kw compressor, it is expected to reduce CO2 emissions by 330 tons annually and save by 17 million yen per year (*1)
