ダイヤ空調 Company Profile

Confident in existence, a perspective towards the beyond.

Noise pollution occurs due to noise from the intake and exhaust vents of machinery rooms and generator rooms. Our full-opening silencers (developed through collaboration between industry, academia, and government) suppress noise from these vents, and we have delivered over 3,200 units to the Ministry of Land, Infrastructure, Transport and Tourism, various power companies, and major corporations. The noise reduction method is based on the characteristics of sound (resonance, interference, expansion) and is registered in the Ministry of Land, Infrastructure, Transport and Tourism's NETIS (New Technology Information System).
