The multistage compressor
comes in two varieties, single-phase and multiphase compression systems.
It is not possible to install the multistage compressor
required in a portable and practical package.
We use this pressure ratio in combination with a multistage compressor
and turbine to allow us to use very low blade speeds in very-high-efficiency machines.
For proper operation of the multistage compressor, an uninterrupted flow of high-quality cooling water is essential for high-pressure applications.
Unlike multistage compressors, which operate at ratios as high as 35:1, booster take advantage of the precompressed plant air and as a result produce as much as 13 cfm for each brake horsepower.
This eliminates the need for the complex water-cooling systems that are required for multistage compressors.
the cost of cooling water for multistage compressors,
the cost of electric power for motor-driven boosters and multistage compressors, and
Compression technology specialist, Ingersoll Rand has a long history of supplying single and multistage compressors
to a wide range of industries in various configurations with power ranging from just 2kW to 25,000kW.
A fundamental feature of buoyant columns is that the large volume needed for hydrodynamic stability offers an unparalleled opportunity for compressed air energy storage at quite low pressures, based on conventional multistage compressors
, and cold air expander/generators of multistage configuration for energy recovery.
The multistage compressors
, for example, have been subjected to a rigorous rotordynamic test programme, taking advantage of the Gas Compressor Test Facility with its 20,000 horsepower (hp) driver, and the capability to test at discharge pressures of up to 3,000 pounds per square inch (psi).
The trend is toward fewer, more highly loaded stages in multistage compressors
