Techniquip Ltd – The importance of measuring Dew Point in Compressed Air

The importance of measuring Dew Point in Compressed Air

• Prevents Equipment Damage: Excess moisture causes internal corrosion in piping and tanks, which leads to rust particles that can clog valves and nozzles. It also washes away essential lubricants in pneumatic tools, causing premature wear and failure.
• Ensures Product Quality: In industries like food, pharmaceuticals, and electronics, moisture can lead to product contamination, bacterial growth, or manufacturing defects (e.g., bubbles in paint, brittle plastics, or ruined semiconductor yields).
• Operational Efficiency: Continuous measuremet allows for “dew point dependent switching” (DDS) in desiccant dryers, which can save up to 80% in energy costs by only regenerating desiccant when truly necessary.
• Prevents System Freezing: In cold environments, if the PDP is not at least 10°C below the lowest ambient temperature, water can freeze in the lines, causing blockages or ruptured pipes.
• Compliance with Standards: Many industries must adhere to ISO 8573-1 air quality classes, which define specific moisture limits that can only be verified through precise PDP measurement.
