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 StarlettePlus-E (SPS) Series Series dryers are the most environmentally friendly refrigeration dryers available. Designed to work with low Global Warming Potential (GWP) refrigerant, R513A, SPS 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.

• Parker StarlettePlus-E refrigeration dryers are developed around a state-of-theart aluminium heat exchanger (E-Pack)

• The E-Pack heat exchanger has a large air/air heat exchanger to pre-cool the incoming compressed air and reduce energy consumption

• The highly effi cient E-Pack design results in a refrigerant circuit with lower absorbed power and uses a smaller volume of refrigerant than other comparable dryers

• The E-Pack design utilizes low pressure drop, cross fl ow heat exchangers to reduce operational costs

• The E-pack heat exchanger includes a high efficiency stainless steel demister separator for liquid removal

• Environmentally friendly, low Global Warming Potential (GWP) refrigerant gas, R513A, on all units.

• All models are equipped as standard with a digital controller that provides an indication of compressed air temperature, volt free alarm contact, service reminder and integral timed drain control

• Optional Energy Saving (ES) models (SPS075 – SPS0250) saves energy by matching power consumption to compressed air demand. The ES models adjust to partial load conditions by allowing the refrigerant compressor to cycle off.
