Gas sampling system AWS-6020

compressed airdew-pointfor SF6

Product Details
The AWS-6020 sample system is designed for trace moisture measurement in gas and general compressed air sampling, enabling the sensor to operate under optimal sampling conditions while safeguarding the hygrometer from high pressures and contaminants, particularly in hydrocarbon environments. Enclosed within an IP66-rated weatherproof cabinet, the AWS-6020 integrates pressure regulation, filtration, flow control, a three-port sample selection valve, sensor holder, dewpoint sensor and dewpoint meter. With this system, both the dewpoint sensor and meter are protected against environmental exposure. Alpha Moisture Systems sample systems provide engineered solutions for extracting and analysing a representative sample of process air or gas, which is subsequently either vented to the atmosphere or returned to the process. This range has been developed through extensive experience in industrial moisture analysis. All systems are constructed from high-quality components to deliver long-term performance and reliability in demanding applications. While a standard configuration is available, this sample system is customisable to suit application requirements.

Applications

• Aerospace: Portable dewpoint meters are crucial in the production of aeronautical parts requiring vacuum furnace heat treatment with very dry argon, and for verifying the dryness of welding shield gas at the torch head according to NADCAP standards.
• HDPE Production: Utilised for spot-checking moisture in flammable gases like ethylene feedstock, portable dewpoint meters ensure safety and efficiency in the production of polyethylene to avoid decreased yields caused by excessive moisture.
• Injection Moulding: Portable dewpoint meters are used to verify the dryness of air circulating through plastic pellets, improving surface finish, colour, and opacity of products — increasing yields and reducing production costs.
• Medical Gases: Essential for ensuring the reliability and accuracy of moisture content in hospital air systems, portable dewpoint meters help conduct continuous monitoring and quarterly spot checks to prevent microbial growth and potential infection — meeting NHS HTM02 standards.
• Speciality Gases: Portable dewpoint meters facilitate accurate moisture measurements in calibration gases, minimising the valuable product expended during the test process and ensuring compliance with specifications.
• Pharmaceuticals: Portable dewpoint meters are crucial for spot checks on inert blanketing gases in medication and medical device production, preventing microbial growth and ensuring the dryness necessary for freeze-drying processes.
• Power Generation: For routine spot checks on hydrogen used in alternator cooling, portable dewpoint meters help maintain efficiency and safety by ensuring moisture is below critical levels to avoid condensation.

Frequently Asked Questions

• Standard configuration includes: an intrinsically safe sensor with sensor holder/sample cell, pressure regulator (heated is optional), filter unit, flow indicator and a pressure gauge (inlet), pressure gauge (outlet) and all pipework in high-grade stainless steel.
• Customisation is available for complex requirements and specific industrial or environmental conditions.
• Maintenance procedures vary depending on application conditions; advice is provided at the design stage.
• For outdoor and hot conditions, the dewpoint transmitter is housed in a stainless-steel enclosure with seals, and vortex coolers can be installed to control internal temperature.
