Until 2023, there were two types of rotary screw compressors: fixed speed compressors and models equipped with variable speed drive (VSD) technology. This year Atlas Copco has introduced the dual speed compressor.

Fixed speed compressors are fairly basic machines that only run at full speed once they are turned on. The advantage for companies that do not want or cannot invest in a VSD compressor is that its purchase price is relatively low. However, unless you need maximum air power all the time (which is almost never the case), a lot of energy is wasted. As a result, your operating costs will be higher.

VSD compressors are the opposite. Their initial investment cost is higher, but they are much more efficient because the motor speed adapts to the demand for compressed air. And, since energy costs make up the majority of a compressor's total cost of ownership, they are more economical to run. From the beginning they can save their users a lot of money.

However, there is now a third type: the dual-speed compressor. This is an ideal solution for those who want more than a fixed speed model can offer, but are not yet ready to purchase a VSD compressor. This new category of compressors is superior to fixed speed models and offers some of the advantages of a VSD compressor.

What is a dual speed compressor?

As the name suggests, dual compressors have two speeds. Like fixed speed models, one of those speeds is the "maximum speed" when users need maximum compressed air power. But it also has a minimum speed for when the compressor goes into unloading mode when the air demand is lower.

It is the second speed that makes the difference, as it generates energy savings in different ways.

Transient losses and discharge losses:

One of the disadvantages of fixed speed compressors is that they experience significant transient losses. This is the loss of energy that occurs as the compressor transitions from one operating phase to another.

These transient losses are a problem from the moment the compressor starts up. The reason is that the fixed speed drive cannot start with a pressurized system. This means that when the compressor starts, it takes some time to build up the necessary pressure. During that time, it consumes energy without yet producing usable air.

When air demand decreases, a fixed speed compressor goes into unloading mode. In this case, the engine runs at maximum speed without producing air. The energy losses that occur at this point are called discharge losses.

When switching to unloading mode, the compressor must also bleed air from the air/oil separator. Otherwise, the fixed speed compressor would not be able to start again later. You may know these types of transient losses as purge losses.

These transient and discharge losses accumulate quickly. Together, they can represent 40% of the energy consumption of a fixed speed compressor. This is the case even with the most efficient fixed speed models. This is because significant transient losses are inherent to fixed speed technology. These compressors simply cannot start with a system under pressure and can only operate at 100% engine speed.

A dual speed compressor reduces transient losses:

A dual speed compressor solves these problems for the most part. It can start under pressure, which means it needs less energy to start producing air. Additionally, you experience much lower venting losses because you do not need to bleed air as drastically as a fixed speed compressor. Finally, the dual compressor's lower unloading motor speed reduces energy consumption.

Adding all of this together, a dual-speed compressor can offer up to 20% energy savings compared to a fixed-speed compressor.

Flexible pressure adjustment:

Another key advantage of a dual speed compressor is that you can select any pressure without affecting the air flow rate or free air delivered. In other words, it works optimally at any pressure setting. Additionally, this allows users to get a smaller dual compressor compared to the fixed speed alternative. In this way, operating and investment costs can also be reduced.

All of these advantages make a dual speed compressor.

2023-02: NEW PREMIUM NGP⁺ N₂ GENERATORS with PSAs technology

The complete, fully automated on-site generator delivers 95% to 99.999% nitrogen purity with best-in-class cost of ownership.




New compressors with a unique intelligent temperature control system, the GA VSDs is the first compressor to offer full control of oil injection, eliminating the risk of condensation and maximizing compression efficiency. An advanced algorithm in the Elektronikon controller combines multiple operating parameters to calculate the optimum oil temperature, which Neos Next implements by regulating the VSD fan and STC valve.

With other compressors, exceeding the maximum flow capacity means a loss of pressure and operation of the equipment, as well as a possible stoppage of production. The GA VSDs features BoostFlow mode, which allows you to temporarily exceed the compressor limit without negative consequences for operation or reliability. The additional boost provides 5% more flow for a total period of 100 hours.

2017-01: Atlas Copco Group divides itself

Atlas Copco AB Board has proposed dividing the Atlas Copco group by transforming the Mining and Rock Excavation business area and the Construction Tools division into an independent entity. This new company will focus on mining and civil engineering clients.

This company dedicated to the mining and civil engineering will have 12,000 employees incorporating all the divisions of the area of Mining and Excavation of Rocks as well as the division of Construction Tools and its after-sales services.
The aim is to ensure that both Atlas Copco and the new company have the best growth opportunities in their respective market segments.
The new entity will have its own Board and a CEO. This will allow to have a more agile company and respond faster to the needs of the market. There will be no changes in the already consolidated operating structure that currently exists and what will allow this reorganization is to invest in areas of growth such as automation, digitization and quality in service.
The new company will trade on the Nasdaq Stock Exchange in Stockholm from mid-2018 following approval at the Annual General Meeting of Atlas Copco in April 2018.

2013-11: ATLAS COPCO PARTICIPATE IN THE " Great Green Wall"

Atlas Copco has decided to participate in a special project, the "Great Green Wall" (http://vimeo.com/user5213989/greatgreenwall) WeForest project organization (www.weforest.org).

This ambitious project aims to gain ground on the nature and repopulate a forest that will tour Africa from east to west. This not only gain ground in the desert, a sustainable local economy in addition to assist the development of farmers, ranchers and their families will be promoted.

And how is going to do...?

For every kilowatt that sells a VSD compressor, will donate a tree to the project. So with the sale of a GA 90 VSD will donate a total of 90 trees. But that's not all, if further accompanied by an Energy Recovery, will increase this amount to 10 trees more!!.

But there's more, because in the case of the new VSD + ...... bend QUANTITY, DONATING TWO TREES FOR EACH SOLD kilowatt!. So with the sale of a GA 11 VSD + donated a total of 22 trees.

All compressors are supplied to the end of the campaign take a sticker on the front that identifies the project in which it participates.

All customers who purchase a VSD compressor Atlas Copco during the campaign will deliver a diploma, which ensure that it has contributed to the planting of a certain number of trees within the project in Burkina Faso.
