Compressed air is generated on-site. Consequently, the quality of the compressed air and cost of producing it are the responsibility of the end user. To achieve maximum performance, the best compressed air quality is required.

The challenge with compressed air systems is that they inherently suffer from performance and reliability issues. Almost all the problems associated with the compressed air system and subsequent product related quality issues can be directly attributed to compressed air contamination.

Compressed air contaminants, derived from the atmospheric air, the air compressor, air storage tanks and the distribution piping, can be categorized into three main groups: particulates, water and oil. Effectively removing or reducing these contaminants down to acceptable levels requires a combination of compressed air filtration and dehumidification equipment.

Parker’s PPD Series of Portable Desiccant Compressed Air Dryers are comprehensive compressed air treatment systems each equipped with multiple stages of a filtration and a twin tower adsorption dryer for compressed air dehumidification. Packaged on portable, heavy-duty skid these highly engineered systems ensure high quality compressed air in accordance with ISO8573-1, the international standard for compressed air quality.

Advantages of PPD Series:

• Heavy duty, draggable skid with lifting lugs and fork holes result in ease of transportation

• Comprehensive system design with two coalescing pre-filters, desiccant dryer and dry particulate after filter ensures clean, dry air in accordance with ISO8573-1

• Optional integrated air-cooled aftercooler with water separator package cools compressed air down to within 15°F of ambient temperature and removes bulk liquids

• Industry leading Allen Bradley® Programmable Logic Controller (PLC) installed in a NEMA 4X enclosure

• Optional Advanced Allen Bradley® PLC includes dewpoint sensor, digital dewpoint display and communication via Modbus RS485 and ethernet

• Selectable cycle modes deliver a continuous dewpoint of -40°F with Standard Cycle or dewpoints as low as -100°F with Short Cycle

• Optional high pressure designs for operation up to 350 psig
