● 10% increase in air volume, reduction in motor capacity By downsizing and re-evaluating the air flow path, we have ensured that air flows smoothly. As a result, we have successfully increased the air volume by 10% compared to conventional models while also reducing the fan motor output. Both the processing and regeneration fans are equipped with inverters as standard, making it easy to adjust the air volume. ● Equipped with high-performance dehumidification rotor D-MAX Our company, which was the first in the world to commercialize a honeycomb adsorption-type dehumidification rotor SSCR using silica gel, has further improved its performance with the D-MAX. It can be used even at 100% relative humidity and is washable. Since all materials are inorganic, it is non-combustible and has sufficient strength. ● Achieved a 50% reduction in weight By using aluminum for the frame and panels, we have successfully achieved a significant weight reduction, cutting the total weight in half compared to conventional models. ● Easy operation and maintenance With a simple, compact design, there are fewer drive and sliding parts, allowing for easy operation and excellent maintenance.

Solving odor transfer issues with ion adsorption. A groundbreaking definitive version for energy saving and CO2 reduction, as well as improving IAQ (Indoor Air Quality). 【Features】 ○ Generally, rotary total heat exchangers use silica gel as the adsorbent, but during the rainy season, water vapor preferentially enters the areas where odor components have accumulated, replacing the odors with water vapor and causing them to be expelled from the rotor, leading to odor generation. The ion adsorption type maintains high performance while solving this odor issue. ○ By using antibacterial and antifungal agents in conjunction, true improvement of IAQ (Indoor Air Quality) has been achieved. ● For other functions and details, please contact us.

● High Performance and High Efficiency We use hydrophobic zeolites and activated carbon with excellent absorption performance as adsorbents, providing sufficient performance for a wide range of VOC types and different operating conditions. ● Treatment of High Boiling Point Solvents When using hydrophobic zeolites, it is possible to regenerate at high temperatures by utilizing their non-flammable and high heat-resistant properties. Therefore, we can also treat high boiling point VOCs that could not be processed due to regeneration temperature limitations with activated carbon. ● Inertness For highly thermopolymerizable VOCs such as styrene and cyclohexanone, we can efficiently process them using hydrophobic zeolites. ● Cleaning and Activation The core concentration rotor is treated with high-temperature calcination, making it a composite of entirely inorganic materials. If clogging occurs, it can be cleaned with water. Additionally, in the case of zeolite rotors, high-temperature activation through thermal treatment (optional) is also possible depending on the situation.
