The company started out by manufacturing expansion valves and 2-cylinder DC piston compressors. By 1959, Martin Bitzer had expanded his company to 206 employees and was exporting his products to 56 countries. In 1961, graduate engineer Ulrich Schaufler took over the Bitzer Kühlmaschinenbau GmbH company. He remained as its head until his death ...
A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure. [ 1 ] [ 2 ] Pressures of up to 5,000 psig are commonly produced by multistage reciprocating compressors.
A similar single stage axial compressors can only increase the pressure by a factor of 1.2 but axial compressors have an advantage over centrifugal compressors because of their ability to have multiple stages. In the multi-staged compressors, the pressure is multiplied from row to row which can increase the pressure by a factor 40.
The Worthington Corporation was a diversified American manufacturer that had its roots in Worthington and Baker, a steam pump manufacturer founded in 1845. In 1967 it merged with Studebaker and Wagner Electric to form Studebaker-Worthington.

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor. Many compressors can be staged, that is, the gas is compressed several times in steps or stages, to increase discharge pressure.
The simplest inlet to a centrifugal compressor is typically a simple pipe. Depending upon its use/application inlets can be very complex. They may include other components such as an inlet throttle valve, a shrouded port, an annular duct (see Figure 1.1), a bifurcated duct, stationary guide vanes/airfoils used to straight or swirl flow (see Figure 1.1), movable guide vanes (used to vary pre ...
NEUMAN & ESSER GROUP (NEA; Neumann & Esser in Aachen) was founded as a family establishment in Aachen, Germany in 1830. NEA is a manufacturer of reciprocating compressors and grinding systems for several industries, including oil and gas, chemical and petrochemical, food industry and renewable energy.
