PoleStar Smart-E (PSE) Series Cycling Compressed Air Refrigeration Dryers - 60Hz & UL Listed for North America

Compressed air systems inherently suffer from performance and reliability issues, most of which can be directly attributed to water in one form or another. In fact, water accounts for up to 99.9% of the total liquid contamination found in a compressed air system. Therefore, air treatment is essential for manufacturing facilities reliant on compressed air for automation.

For general purpose or non-critical use of compressed air, refrigeration dryers are an ideal choice. Refrigeration dryers utilize a closed loop cooling system to lower the temperature of the compressed air to just above freezing, causing condensation of water vapor.

Most of the condensed liquid is then removed by an integral water separator and drained away. Prior to leaving the dryer, the compressed air is re-heated by the incoming compressed air to prevent condensation on the outside of the downstream distribution piping.

Refrigeration dryers should always be installed with general purpose and high efficiency coalescing filters and are an effective way to reduce water vapor, liquid water and water aerosols for general purpose compressed air applications.

Parker’s PoleStar Smart-E (PSE) dryers are the most environmentally friendly refrigeration dryers available. Designed to work with low Global Warming Potential (GWP) refrigerant, R513A, PSE complies with the requirements of the United States Environmental Protection Agency SNAP Rules 20 & 21 and European F-Gas Regulation (EU 517/2014). This makes Parker PSE the best choice to protect your investment, the climate and the environment.

• State-of-the art aluminum SmartPack heat exchanger (HX) includes a large air-to-air HX to pre-cool incoming compressed air and reduce energy consumption

• Efficient SmartPack HX, electronic hot-gas valve and innovative micro-channel condensers result in lower adsorbed power and about 40% less refrigerant verses additional solutions

• Low pressure drop design of the Smart-Pack HX and low absorbed power of the refrigerant circuit make PSE dryers a highly competitive solution with lower operating costs vs comparable dryers.

• Comprehensive electronic controllers, including touch screen panels on PSE700 and larger, provide indication of compressed air temperature, service reminder, data log, alarm history, integral capacitive drain control and much more.

• LED unit status indicator on model PSE1400 and larger.

• High and low pressure gauges for refrigerant circuit on models PSE700 and larger.

• Remote communication protocol, industry 4.0 ready, on all units; web server from model PSE700 and IoT ready from model PSE1400.

• Energy savings technology that enables all PSE dryers to save energy by cycling the refrigerant compressor off at partial load while maintaining a constant outlet dewpoint.

• Variable speed fans on PSE1400 and larger deliver additional cost savings at partial load and increased condensation stability.

• Compliant scroll refrigeration compressors offer longer life, lower noise and energy savings of up to 20% compared to piston alternatives.

• Inlet and outlet air connections installed on both sides of PSE2000 and larger allow for installation flexibility and simplify banking multiple units together.

• Low Global Warming Potential (GWP) refrigerant, R513A, used on all PSE units – protecting the environment.
