AERZEN Positive Displacement Blowers

For Conveyance and Compression of Process Gases

Series GR/GQ, volume flows from 100 m3/h to 100.000 m3/h

AERZEN Process Gas Blowers

Robust technology for every process. AERZEN process gas blowers have proven themselves in thousands of installed units all over the world. What are the decisive factors? Extremely long service life. Sharp focus on efficiency criteria. And also this: the unusually broad portfolio of solutions, including modifications, accessories, and special developments to ensure they meet every possible process requirement.

• Rightsized for the process. Design based on customer requirements as the basis for optimal energy efficiency. AERZEN’s process gas blowers are radically flow-optimized. Carefully selected transmission variants are just as important to increasing efficiency as innovative component developments. But the decisive factor in reducing energy consumption is this: every compressor and blower unit from AERZEN is tailored to the individual requirements of our customers and their processes. Rightsized and thus especially efficient.

Focus on Special Requirements

• AERZEN is a pioneer in compressor technology. In many areas, we are the market leader. With unique technological advantages. With superior quality and high efficiency. Our product portfolio for the process gas and coolant industries includes a broad spectrum of specialized blowers and compressors, high-end machines with a wide variety of designs, sizes, and special features. Configured so they meet all relevant international regulations, building codes, and specifications in a wide variety of industrial branches and certification bodies. Including ASME, API, TEMA, ANSI, Ex and DIN, the European Pressure Equipment Directive (PED), as well as safety regulations for electrical installations such as DIN, EN, NEMA, IEC, and ATEX.

Working Method and Range of Application

• Positive Displacement principle, i.e., automatic adaptation to possibly changing operating conditions.
• Volume flows from 100 to 50000 m3/h
• Pressure difference up to 800 mbar
• Insensitive to impurities in the gas, such as particles of dust, tar, and dirt, or parts of liquid
• Suitable for continuous liquid injection for gas cooling or cleaning of the conveying chamber
• Usable for nearly all technical gases and gas mixtures in all industrial ranges
• Ideal use for gases with negative intake temperature
• Optimal use at high intake temperatures up to 110 °C
• Oil-free handling (100% separation of oil chamber and rotor chamber)

Type GR Oil-Free Rotor Chamber

The Seal Variants

A variety of seal systems are used to ensure that the gas side and lube oil area remain separate. These systems are examined in detail below. Depending on the individual characteristics of the gas to be compressed, the process gas machines can be equipped with the following seal systems.

Design Features

In terms of the basic concept, the GR series represents an extension of the standard GM blower, and its most important characteristic is that the rotor chamber is designed to be completely separate from the oil chambers. This ensures that neither the lube oil in the rotor chamber nor the conveyed medium can penetrate into the oil chambers.

Timing Gears

All GR blowers are equipped with helical-toothed, hardened, and ground gears. They are fastened to the shafts by means of a taper interference fit.

Seal on the Rotor Chamber

Restrictive carbon ring labyrinths, dry. The sealing of the conveying chamber depends first and foremost on the conveyed medium and the required leak rate. For dry media free of dust and tar, restrictive carbon ring labyrinth seals with exhaust and seal gas admission flow are used because they offer exceptionally low abrasion and allow higher speeds.

Double-Acting Mechanical Seals

These seals require a locking fluid to facilitate locking and heat removal. Water and oil are the preferred locking media.
