Optimal System for Your Goals

  • Industrial Humidification Systems

    An industrial HVAC humidification system that optimizes on-site humidity, designed by our specialists based on an site assessment. Our atomization technology, which uses compressed air, generates Dry Fog, an ultra-fine mist that does not wet surfaces on contact. The system precisely controls humidity across large spaces as well as in localized zones, helping prevent static electricity-related problems.

  • High-Pressure Humidification Systems

    An industrial HVAC humidification system that atomizes water with a high-pressure pump, without using compressed air. The system generates “Semi-Dry Fog” with a mean droplet diameter of 10 to 30 μm. With its high humidification capacity, the system maintains stable humidity levels even in large spaces. Compared to conventional humidification methods, it offers higher energy efficiency and helps reduce environmental impact.

  • Hybrid Humidification System

    This hybrid humidification system combines hydraulic and pneumatic water atomization. The high-pressure pump method (AirULM) maintains stable humidity levels throughout the entire space, while the compressed air method (AirAKI) provides localized humidification in specific areas. It quickly achieves optimal humidity levels, making it ideal for high-ventilation sites such as gravure printing plants.

  • In-AHU Humidification System

    An industrial HVAC humidification system for environments where direct humidification is not feasible, such as cleanrooms. Installed inside an air-handling unit (AHU) or ductwork, it provides indirect humidification without releasing fog into the room. Flexible design and layout options enable a site-specific configuration. With a saturation efficiency of 90% or higher, the system delivers a uniform, stable humidity environment.

  • In sheet-fed printing, dry conditions lower the paper’s moisture content, causing feed failures and register misalignment that can lead to line stoppages and paper waste. Dry Fog humidification maintains humidity without wetting paper, enabling stable operation and maximizing production efficiency.

    Learn More

  • Gravure printing requires continuous ventilation due to the use of organic solvents, creating a dry environment. Insufficient humidity accelerates ink evaporation and static electricity, increasing fire risk and reducing print quality.

    Learn More

  • In label printing, many substrates such as films and pressure-sensitive papers are prone to static buildup; when humidity is insufficient, static electricity can occur at the peeling and rewinding sections, causing curling and poor adhesion. Stable humidity control helps prevent static buildup and dust adhesion, supporting consistent print quality.

    Learn More

  • In screen printing, as dryness increases, stencil clogging, ink misting, and substrate shrinkage or warping can make transfer defects more likely to occur. Dry Fog humidification stabilizes humidity to maintain transferability and color reproduction, helping reduce waste and improve efficiency.

    Learn More

  • Because digital printing prioritizes short runs, high mix, and speed, insufficient humidity can cause feed issues and fusing defects, resulting in print misregistration and color inconsistency. Dry Fog humidification stabilizes humidity to ensure stable operation and high-quality printing.

    Learn More

  • When paper dries, its moisture content drops, causing dimensional variation and reduced strength. Dry Fog humidification maintains humidity without wetting the paper to stabilize moisture content, helping prevent score cracking and bonding defects during converting, as well as quality degradation during storage.

  • In the spinning process, dry conditions can cause weight loss and defects due to yarn breaks. Dry Fog humidification provides precise humidity control to stabilize yarn moisture content, supporting consistent quality and stable production.

    Learn More

  • In the weaving process, dry conditions lower yarn moisture content, reducing its strength and elasticity. As a result, yarn breaks increase, leading to machine stoppages. Dry Fog humidification stabilizes humidity to reduce yarn breaks, improving weaving efficiency and quality.

    Learn More

  • When nonwoven fabrics dry, fiber entanglement weakens, causing dimensional variation and reduced sheet strength. Insufficient humidity exacerbates static electricity and elevates the risk of dust-adhesion defects. Proper humidification stabilizes fiber moisture content, supporting consistent product quality and production efficiency.

  • Humidification is essential in automotive manufacturing. In painting processes, dry air can lead to dust adhesion and paint defects, directly impacting quality. Proper humidity control stabilizes process environments and delivers a higher-quality finish. It also delivers benefits in other processes, including welding and assembly.

  • In food packaging, dry air can cause films to build up static, leading to conveying failures and packaging defects. Dry Fog humidification maintains uniform humidity, suppresses static electricity and airborne dust, stabilizes sealing and weighing operations, and helps maintain a hygienic packaging environment.

  • A high-humidity environment is essential for mushroom growth, but water droplet adhesion can cause spotting and reduce mushroom market value. Dry Fog humidification maintains humidity without wetting the growing media or the crop, helping prevent appearance defects and mold. It stabilizes yield and quality while supporting efficient cultivation.

  • In wine aging, insufficient humidity can cause barrels to shrink, increasing cracking and evaporation that may lead to oxidation and flavor degradation. Dry Fog humidification uniformly humidifies the air in the cellar to stabilize its humidity level, suppressing evaporation losses and minimizing topping-up work to create stable aging environments and protect quality and flavor.

  • UNIQUE NOZZLE TECHNOLOGY The Story Behind Our Innovation

    Dry Fog Humidification
    Pioneered Through Proprietary Nozzle Development

    Learn More

    What we set out to create was “Dry Fog,” a mist that does not wet surfaces, even on contact.
    After extensive trial and error, AKIJet®, an ultra-fine atomizing nozzle that produces droplets with a mean diameter of 10 μm or less, was born.
    The name reflects the founder’s deep connection to Aki in Hiroshima, Japan, his hometown.
    This technology remains at the core of industrial humidification to this day and continues to be chosen worldwide.
