Product Feature

Flow Chart

1.Filtration & compression
The air is drawn into the compressor through the inlet filter where the air is cleaned. It then continues to the first compression stage where the air is compressed to an intermediate pressure.
2.Cooling & second compression
After the first compression, the air is cooled down in the intercooler. Once the air is cooled down, it passes through a moisture separation system before entering the highpressure stage. In the high-pressure stage, the pressure is brought to its final pressure.
3.Exchanging heat & cooling
The hot wet compressed air at the outlet of the highpressure stage goes through the pulsation damper with integrated check valve to the heat exchanger. Here it transfers the heat to the integrated dryer used further in the process.
The air continues to the aftercooler where it's cooled down and the moisture get's separated and drained.
4.Integrated dryer-for FF
The cooled wet compressed air is now mixed with 40% of the cooled regeneration air and enters the dryer. The dry compressed air with guaranteed dew point is now ready for use in your application.
5.Heat exchanger
40% of the dry air goes into the heat exchanger, where it picks up the heat from the incoming hot wet compressed air. This dry and hot regeneration air enters the regeneration section of the drum, which passes through the regeneration cooler where it is cooled down and moisture is separated and drained. Afterwards it is mixed with the incoming cooled wet compressed air.
6.Oil
The yellow lines represent the oil flow of the compressor. Oil is pumped from the reservoir through a high efficiency filter to provide clean, cooled oil to the gears for lubrication. Afterwards the oil flows back into the reservoir. There also is a bypass valve that allows the oil to flow to the oil cooler, so the optimal temperature is guaranteed, increasing efficiency and durability of our components.
7.Water
The dark blue lines represent the water flow. Cooling water is brought into the cycle and splits towards the both modules and the dryer.
First of all, the cooling water is directed to the integrated dryer to cool the
Secondly, the water is goes to both the inter- and aftercooler to reduce the temperature of the compressed air.
Lastly, the water splits to the oil coolers to reduce the temperature of the oil. It then passes through the jackets of the motor and elements to guarantee an optimal temperature. The water continues back to the cooler and is directed further to the water outlet.

For VSD

Heat recovery system-recover up to ≈ 75%-Optional

Recovering compressed heat means you can reduce or eliminate boilers and other equipment that provide heat or steam for production.
This allows you to save costs on installation, maintenance, energy, and carbon emissions. Based on your compressed air system, an energy-saving potential calculator can be used to determine possible energy efficiency gains-showing how much heat you can recover and how much you can save on energy costs.

Such as you can utilize the recovered heat to warm water for worker showers, saving the cost of electricity, coal, or other resources traditionally used to heat water.

* Auxiliary or main heating of warehouses, workshops…
* Industrial process heating.
* Water heating for laundries, industrial cleaning and sanitary facilities.
* Canteens and large kitchens.
* Food industry.
* Chemical and pharmaceutical industries.
* Drying processes.

Smart air solution-optional

Only a complete compressed air system is an energy efficient and reliable solution that delivers the correct compressed air quality. That is why call the solutions smart AIR solutions.

1.Central Controller

A key component in a smart AIR solution is a central controller. They will control a multiple compressor installation in a more efficient way than the individual machines can with their local

settings. But they also provide you with connectivity solutions, whether it is to disclose the controls to any device in your LAN, add advanced local visualization features, connect to your SCADA

system or to our unique connectivity solution SMARTLINK, which will give you unique insights and provide you with suggestions and solutions for improved uptime or energy efficiency. A central controller is like a conductor of an orchestra: it will take the best of the individual components of your installation and makes sure everything stays in tune, while providing extra transparency that

would otherwise take major efforts to be gained.

2.Energy efficient and reliable compressors

All smart AIR solutions start with picking the correct components in the correct combination. Choosing energy efficient compressors, paying special attention to the mix of compressors will be a major contributor to a smart AIR solution. Our sound proof design contributes to a better working environment around the compressors. Our compressors have been designed with maintenance in mind, reducing the downtime of machines and improving availability of compressed air.

3.Variable Speed Drive (VSD) compressors

Compressed air demand of most applications varies widely. Adding one or multiple VSD compressors to the installation will greatly help to improve energy efficiency of the total installation,

stability of compressed air pressure and reliability, thanks to more stable regime of each machine.

4.Ventilation

Compressors generate heat. Adequate evacuation of this heat will ensure favorable working conditions for compressors and dryers alike.

5.Air receiver

Even with a Variable Speed Drive compressor, having an appropriately sized buffer tank for compressed air will help smoothening the variation in demand and allow compressors to work in more stable operating conditions, thus helping both energy efficiency and reliability

6.Compressed air dryers

The correct choice of dryer technology corresponding to the compressed air quality requirements is crucial to a reliable and energy efficient compressed air installation. The choice for integrated dryers - our full feature concept - will have additional benefits, reducing installation cost, time and complexity, having dryers controlled together with the compressors, reducing connecting pipes, hence the chance of leakages and extra pressure drops. And look at the major space saving full feature machines can bring. Smart AIR solutions have impact on every aspect of your compressed air installation.

7.Compressed air filters

Also the correct filter grade in correspondence with air quality requirements will be an important contributor in a smart AIR solution. This goes hand in hand with correct maintenance of the filters, as incorrectly maintained filters will jeopardize both the reliability of your installation as the energy efficiency

8.Air Distribution Net

Most factories grow organically over time. With every extension, there is an increasing risk introduced in the air distribution net: undersized and heavily corroded pipes, restrictions, massive

leakages. Whenever a compressed air system is audited, it is common to find massive opportunities there. Atlas Copco's unique AIRNET pipe system will deal with all of these: our sizing tools and

assistance from our engineering team will help to size the distribution net correctly. And with a choice of aluminum, plastic and stainless steel components, there's no need to fear for corrosion over time. And there is no need to worry about leakages, as all couplings have proven leak tight over time. AIRNET comes with a guarantee of 10 years, that is how much we believe in our solution.
