Construction sizes, construction type and performance range

Compressor Systems

NEUMAN & ESSER offers the best compressor solution for all customer requirements. The NEA compressor portfolio incorporates various construction forms: the horizontal boxer design, the vertical reciprocating compressor and the V version of the reciprocating compressor. The diaphragm compressors from HOFER complement the program. More than 8 different crankcase sizes in accordance with Standard API 618 as well as many other crankcase sizes according to the NEA Standard are available to the customers.

The gas-tight design of some construction sizes denotes a further special feature, guaranteeing emission and leak-free compression. The key data of the NEA compressors include discharge pressures of up to 1,000 bar, an effective suction volume flow of up to 150,000 m3/h and driving power from 5 kW to 30 MW, the most extensive capacity range in the reciprocating compressor market. Additions to the performance range are achieved using compressor combinations, that is to say combining different compressor construction types.

Oil-free, non-lubricated compressors

In particular, the food chemistry sector and the chemical industry demand highly pure, oil-free gases. NEA developed the so-called dry runners many decades ago for this challenging task. Here, neither oil nor lubricants come in to contact with the gas, which keeps the gas absolutely oil-free. This saves the customer downstream cleaning procedures of the gas, which are both complex and expensive.

Lubricated compressors

In applications with high discharge pressure, considerable compression temperatures occur. For special demands on service life, oil-lubricated compressors are the right choice. NEUMAN & ESSER applies oil-lubricated compressors in these fields to optimize sealing behavior and thus to significantly increase service life.

Emission-free crankcases

NEUMAN & ESSER is environmentally aware. NEA has therefore developed an emission-free crankcase for leak-free compression. By this means, no harmful, polluting gas is emitted to the atmosphere. Likewise, high-grade and expensive gases cannot escape, which saves the customer immense costs.

Gas tight crankcases

In Europe, the USA, and among globally active groups in the petrochemical and oil & gas industries, the demand for "zero emissions" from machines and plants is becoming increasingly entrenched in the interests of sustainability and environmental protection for operators. Accordingly, greenhouse gases such as CO2 and CH4 or toxic gases must no longer be released into the atmosphere. NEUMAN & ESSER offers gas-tight crankcases that meet these requirements. Read more
