- Key Products/Technologies
- AIREX Industrial Heating, Cooling, and Dehumidification Solutions: Development and production capabilities for industrial portable air conditioners (HSC-Series, HSC-3270R, HSC-1270R, HSC-6100N) optimized for high-temperature work environments. Features include flexible discharge ducts for partial and concentrated cooling, with optional extension up to 12m. Digital controllers offer timer, temperature/airflow adjustment, remote control, and self-diagnosis functions. Water-cooled air conditioners (HWC series) provide powerful cooling without exhaust heat, consuming 20-30% less power than air-cooled models and operating stably in 50℃ high-temperature conditions. A diverse lineup of far-infrared heaters (AH-Series, AH-1339, AH-730M) and industrial dehumidifiers (ADH-1000,800, ADH-600P) is also available.AIREX Industrial Heating, Cooling, and Dehumidification Solutions: Development and production capabilities for industrial portable air conditioners (HSC-Series, HSC-3270R, HSC-1270R, HSC-6100N) optimized for high-temperature work environments.
