Aerzen  Process Gas Blowers

Aerzen  GR Process Gas Blowers

(GR Series - 58.86 to 29,430 CFM)

BLOWER POWER FOR SPECIAL APPLICATIONS.

The 1 or 2 stage process blowers GR can be used for almost all technical gases and gas mixtures, , which may also be aggressive. In all branches of industry. They are also ideal for gases with negative intake temperatures down to -30 °C.

DESIGN:

The conveying chamber sealed by

•Pressure relieved soft packings with purge gas connections,
•Pressure relieved carbon ring - labyrinth seals with purge gas connections,
•Double-acting mechanical seals, oil-purged
•Double-acting mechanical seals, water-purged
•Drive shaft by radial seal ring.

DIRECTION OF FLOW:

•Vertical, from top to bottom.

Aerzen  GQ Process Gas Blowers

(GQ Series - 8,829 to 58,860 CFM)

GQ process gas blowers are ideal for use in steel plants for the compression of process, cooling, and seal gas. These blowers are often used as 2-stage units and are up to the most extreme challenges.

FIELDS OF APPLICATION:

•Especially used in direct reduction plants for conveying of process- and cooling gas.
•Operating pressure range up to max. pe=2,5 bar where the medium has the corresponding inlet pressure.
•Max. pressure difference 1100 mbar.
•Especially used in direct reduction plants for conveying of process- and cooling gas.
•Operating pressure range up to max. pe=6 bar where the medium has the corresponding inlet pressure.
•Max. pressure difference 1500 mbar.

DESIGN:

•Housing compression-proof for PN 2,5. Cylinder with noise reducing chamber on the discharge side, housing with connections for water injection - and water flushing, as well as for lubrication - and purge oil supply systems.
•Housing compression-proof for PN 6 (only GQ 20f20 and GQ 21.21). 
•Cylinder with noise reducing chamber on the discharge side, housing with connections for water injection - and water flushing, as well as for lubrication - and purge oil supply systems.

SHAFT SEALINGS:

•Conveying chamber by single-acting oil-purged mechanical seals in combination with labyrinth seals.
•Drive shaft is sealed by 3 radial seal rings.

DIRECTION OF FLOW:

•Horizontal, selective to the left or to the right

DRIVE:

•Either via flexibly coupled spur gear or direct coupling with drive motor.
•Via flexibly coupled spur gear.

Aerzen Delta Blower

(14 – 67 hp • 1750-5000psi)

The Delta Blower Generation 5 is the synthesis of the successful characteristics developed in previous generations combined with new technical innovations that already meet the market requirements of the future. Aerzener Maschinenfabrik was the first blower manufacturer to design compact units in 1960 and has developed this machine type continuously ever since. Delta Blower Generation 5 is therefore already the 5th generation of AERZEN blower units and represents the successful combination of tradition and innovation.

ADVANTAGES  OF AERZEN DELTA BLOWER GENERATION

•Low noice levels due to considerable sound reductions
•Operation-friendly & low maintenance design
•Mechanical fan
•No absorption material
•Space-saving side-by-side setup
•Energy-efficient design
•Aerzen base support certified as spark arrester for ATEX-applications
•Oil-free per Class 0 (certified according to ISO 8573-1)
•Blower stage with patented procedure for pulsation reduction
•Standard application for energy saving motors of class IE3
•Automatic belt retention due to hinged motor mounting plate
