Industry Pain Points Moisture Corroding Key Equipment: Moisture in compressed air causes rusting of pneumatic components, shortening the average service life of solenoid valves from 5 years to 1.5 years and increasing annual maintenance costs by 35%. Oil-Water Mixture Contaminating Products: In the food/pharmaceutical industries, compressed air containing oil and water (0.5-5ppm) leads to packaging…

Industry Pain Points Difficulty in Deep Removal of Trace Oxygen: Crude nitrogen from air separation contains 1-1000ppm oxygen. Traditional catalytic deoxygenation processes result in residual oxygen ≥0.1ppm, failing to meet the requirement for electronic-grade nitrogen (≤0.01ppm). Hydrocarbon Contamination: CH₄/C₂H₆ (0.5-5ppm) produced by lubricating oil cracking poisons deoxygenation catalysts, shortening their service life from 5 years…

Industry Pain Points Ultra-Low Dew Point Requirement: Lithium-ion battery production demands compressed air with a dew point of ≤-40℃ (some processes require -70℃), which traditional refrigerated dryers (+3℃) cannot meet at all. Zero Oil Pollution Challenge: Electrode coaters are sensitive to oil content (requiring ≤0.001ppm). Conventional adsorbents are easily poisoned by oil mist and fail…

Industry Pain Points High Salt Spray Corrosion: The air in coastal shipyards contains 5-15mg/m³ of salt. Heat exchangers of traditional drying equipment suffer corrosion and perforation within 3 months, increasing maintenance costs by 300%. Large Flow Fluctuations: The air consumption for hull sandblasting fluctuates instantaneously by ±50%. Conventional drying systems have delayed responses, leading to…

Industry Pain Points High Corrosion Risk: Chemical compressed air contains acidic gases (e.g., H₂S, SO₂) and organic solvent vapors, causing corrosion and perforation of traditional drying equipment, with an average service life of less than 3 years. Severe Oil-Water Pollution: The exhaust of screw compressors contains 5-50ppm oil and saturated moisture (dew point +40℃), which…
