DABECO DB481: Smart Humidity Control for Energy-Efficient Sizing Machines

Temperature and humidity sensors

Sizing machine exhaust contains water vapor, smoke, and hot air. To increase water vapor/smoke content, reduce hot air emission, and cut energy consumption, the National Development and Reform Commission’s "Access Conditions for the Dyeing and Printing Industry" mandates online humidity monitoring for sizing machines and drying processes.
Current manual humidity adjustment (via exhaust fan valves) relies on experience, causing significant energy waste due to large errors. Intelligent monitoring is key to energy savings. Drying cost is closely linked to temperature and humidity: evaporation efficiency and energy consumption show nonlinear changes with exhaust humidity. Below 20% exhaust humidity, energy consumption surges while efficiency barely changes. Thus, 20% is the optimal exhaust humidity for dryers.
Sizing machines have less than 30% heat utilization, with major heat loss in exhaust. Tests show: at 5% exhaust humidity, air volume is 19x that of water vapor; at 20%, it’s only 4x. The heat from this 15x difference is completely wasted. Installing high-temperature humidity sensors like DABECO DB481 (Beifang Measurement and Control) can automatically control drying humidity, drastically reducing heating costs.
DABECO DB481 offers advantages including 200°C resistance, anti-pollution, and anti-condensation, providing stable data support for sizing energy-saving systems.
Founded in 1992, Beifang Measurement and Control (DABECO) has independent R&D, production, and sales teams, and is ISO9001 certified. Its products, equipped with Swiss chips and based on Swiss MEMS technology, cover temperature, humidity, and water quality monitoring, widely used in construction, HVAC, medical, and other industries. The humidity meter series (sensors, transmitters, controllers) – from chip-level to industrial high-temperature models like DB481 – feature stable signals, diverse packaging, and wide measurement ranges.
