Company information
For sites that produce and process precision machinery, dust, dirt, and chemical substances, even if they are so fine that they are invisible to the eye, are formidable enemies. Recently, from the perspective of strengthening management through HACCP (Hazard Analysis Critical Control Point), efforts are being made in food and pharmaceutical factories to remove airborne particles and microorganisms, maintaining indoor cleanliness. Therefore, clean rooms that can remove substances at the micron level have become indispensable in these manufacturing processes. At Nitto Cold and Heat, we have consistently integrated cooling technology, air purification technology, and temperature and humidity control technology at a high level, designing, producing, selling, and providing services for clean room system equipment for over 30 years.
