Scroll TechnologyQuiet, Durable, Perfectly Balanced, Efficient,
Compact, and 100% Oil-free
The scroll compressor dates back to when Leux Creux first invented the concept in 1905. The idea laid dormant for much of the century due to the high tolerances required in sealing the compression chambers. The manufacturing techniques available at Creux's time could not accommodate these tolerances. It was not until the 1970's that the scroll concept was revisited.
The scroll compressor has no valves and fewer moving parts when compared to reciprocating compressors. Additionally, the rotary motion of the scroll compressor makes it possible to completely balance the compressor. These factors increase reliability and performance and are responsible for attracting copious research and development over the years.
Due to several advantages of the scroll compression process, they continue to replace traditional reciprocating, diaphragm, and vane compressors in a variety of applications.
- Fixed Scroll
- Orbiting Scroll
- Drive Pin
- Idler Shafts
The scroll pack contains one inlet ports a discharge port and two acting chambers on either side of the compressor. At any one point during operation, there can be as many as three compression processes occurring simultaneously. There are two chambers formed by close interaction between a fixed and orbiting scroll involute curve. The 1st chamber starts on the inside of the fixed scroll wrap and is half a wrap shorter in length than the 2nd chamber located on the outside of the fixed scroll wrap. Each chamber goes through the same processes.
- The scroll compressor can be completely oil-free.
- Rotary type motion allows the compressor to be perfectly balanced for low vibration and noise.
- There are no valves or other wearing parts.
- A scroll compressor can run at higher speeds of 6000 rpm or higher without compromising quiet, efficient operation.
- Scroll compressor can be manufactured at a competitive cost using Air Squared’s manufacturing techniques.
- A scroll compressor is a positive displacement compressor which results in higher efficiency and high pressure capability.
- There are only two primary moving parts resulting in high reliability and simplification of the manufacturing process.
- Rubbing velocity is low resulting in low noise and low wear.
