Oil-free air rotary screw compressor
ZR/ZT 75-160VSD+
Setting the standard in energy efficiency, safety and reliability
The shortest route to superior productivity is to minimize
operational cost while maintaining an uninterrupted supply of the
right quality of air. The Atlas Copco Z compressor series is
focused on efgectively saving energy, ensuring product safety –
only oil-free machines exclude contamination risks for 100%– and
guaranteeing the utmost reliability around the clock. And not just
today, but day afuer day, year afuer year, with minimal maintenance
cost, few service interventions and long overhaul intervals.

Flowchart
Process flow, oil flow and cooling flow - step by step
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
Afuer 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 high-pressure 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 high-pressure 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 afuercooler where it's cooled down and the
moisture get's separated and drained.
4. Integrated dryer
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. Afuerwards 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 efgiciency filter to
provide clean, cooled oil to the gears for lubrication. Afuerwards
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
efgiciency 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 afuercooler 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.
