The Diamond Ventilation Silencer is a groundbreaking silencer that "eliminates sound using the characteristics of sound," which is unlike any conventional silencer. Noise pollution occurs due to noise from the intake and exhaust openings in machine rooms and generator rooms. Our full-opening silencer (developed through collaboration between industry, academia, and government) suppresses noise from these openings and has been delivered to over 3,200 units to the Ministry of Land, Infrastructure, Transport and Tourism, various power companies, and major corporations. It employs a method of sound attenuation based on sound characteristics (resonance, interference, expansion) and is registered in the Ministry of Land, Infrastructure, Transport and Tourism's NETIS (New Technology Information System). 【Features】 ○ High sound attenuation capability, including low-frequency ranges ○ Low pressure loss (approximately 50Pa) ○ Reduces fan output, leading to lower running costs ○ No maintenance required ○ Compact shape for easy installation ○ Can be installed in existing ventilation systems ● For other functions and details, please contact us.

Radiant heat from slate and metal roofs raises indoor temperatures, significantly compromising comfort and work environments. The Diamond Insulation Method, developed by our company using the IL Joiner, involves applying insulation material (glass wool) to the ceiling and walls from the inside, greatly contributing to the reduction of radiant heat and the improvement of work environments. 【Features】 ○ Prevention of heat radiation from slates, etc. ○ Prevention of heat release from indoors ○ Reduction of indoor noise ○ Improvement of indoor aesthetics ○ Applicable to both existing and new constructions ● For other functions and details, please contact us.
