Process-Gas Screw Compressor
Process-Gas Screw Compressors are used in all applications where heavily contaminated components in gases and gas mixtures would curtail the life of other types of compressors. Their low speed of rotation permits direct injection of large quantities of liquid.
These oil-free compressors attain volume flows of up to 100,000 m³/h and an outlet pressure of 50 bar.
They are used in innumerable applications:
* Refineries
* Petrochemical plants
* Chemical production plants
* Oil and gas production
* Plants for iron and steel production
* Mining.

GEAR series
The new power packs for extensive compressed air requirementsPower class: 30 – 500 kW The gear-driven plants of the GEAR series enable ALMIG to offer a new generation of screw compressors for extensive air requirements. Delivery quantities of between 3.58 and 71.15 m³/min at max. operating pressures of 8, 10 and 13 bars.
With drive outputs of 30-500 kW the plants are available in an air-cooled (30-250 kW) and a water-cooled version (30-500 kW).
The easy-to-maintain and service drive concept with a robust drive motor with generous power reserves, easy-to-maintain and service gear and novel flexible gear drives with replaceable working elements protect the drive, work with minimum slip but with high operational reliabilityand virtually without loss (efficiency >98%). Highly efficient separation of the cooling agent facilitates a residual oil content of only 2–3 mg/m3.

Within the compressor body there are two screws with matting profile: a female and a male screw, female having concave inlets and the male with convex helical inlets. The screws rotate in opposite directions with the female screw receiving the driving power and transmitting this power to the male screw through a set of synchronization gears.
As the screws rotate, the air is drawn into the inlet port and fills up the space between the screws. This phase is the Admission. The key phase is the Compression. It starts when the end of a male thread blocks the end of a female thread. The volume available between the compressor body and these two threads then progressively decreased during rotation. When this volume merges into the delivery outlet of the compressor, the third phase takes place, hence the Exhaust.
Throughout this process, there is no contact between the screws. This means no wear, total reliability, and non-pulsating air delivery. These compressor/blowers can be used in either a Mobil or stationary application and can be driven by a PTO, electric motor, or hydraulic power system. A complete range of dedicated ancillary product is available to support this product line.

VARIABLE series
Power class: 16-315 kWThe speed-controlled, screw compressors in the ALMIG VARIABLE series have been specially developed according to the most recent findings in research and technology. They are for use in all situations where compressed air needs vary.
Market analyses show that on average capacity utilisation of compressors is around 50 - 70%. The maximum delivery quantity is only required at peak times.
This has prompted us to develop the ALMIG SCD technology which demonstrates its greatest strength in the partial load range, i.e. exactly where it is required.

Vyper Variable Speed Drive
The Frick Vyper Variable Speed Drive for screw compressors offers the refrigeration industry superb system performance, enhanced energy savings, and reduced maintenance costs.
The Vyper VSD provides fast, precise, and wide-ranging response to rapidly changing loads. The liquid-cooled, NEMA 4 rated cabinet provides protection from ammonia vapors while the Quantum™LX control panel provides a user-friendly interface for ease of operation. The drive is available in 150, 305, 435, 687 and 957HP models and can be mounted either directly on the compressor package or remotely.
The package mount method provides easy on site installation of new equipment while the remote mounting method offers an easy solution to retrofitting a constant speed drive with the Vyper VSD for energy cost savings and or enhanced performance.
Replacement with a conventional screw compressor with mechanical capacity control (slide valve) can not provide the rapid response to load fluctuations, but when the Frick screw compressor with variable Vi control is driven by the Vyper VSD, rapid response is no longer a concern.
The Vyper is capable of starting and coming up to full speed in 10 seconds. Capacity control with speed, as low as 20% (720RPM) means the slide valve should never move for capacity control. This results in virtually no wear to the slide valve. Also, since the slide valve stays loaded, economizers are always at full capacity and Vi control which fluctuates as the slide is unloaded stays Ideal through the speed range using the Vyper VSD.
