Technical Specifications and Equipment Description

•   Having the right air quality protects your production
-   Compressed air is used in a wide variety of manufacturing and commercial operations. Air is generated from the ambient atmosphere around the compressor and typically would contain contaminants in the form of dust and water which are two naturally occurring impurities while a third impurity which is oil typically gets added to compressed air due to the compression process. Oil though can be avoided/eliminated by using our 100% oil-free compressors.

•   ZR 90 VSD
-   Oil-free air compressor elements (Class 0)
-   Unique seal design guarantees certified oil-free air

-   Compressor elements with superior coating, optimized design and low loss bearings and seals ensure highest efficiency.
-   Efficient intake filtration for minimum losses and low pressure drop.
-   Coolers are designed for efficiency with low pressure drop and low air approach temperature, ensuring coolest possible running conditions.
-   Our fixed speed machines come with IE4 super premium efficiency motors, giving you extra energy savings, every hour the machine runs.
-   VSD machines are equipped with IE3 premium efficiency motors, in combination with our highly efficient in-house designed Neos frequency converter.
-   With machines typically running 4000 to 8000 hours per year, again a major contributor to energy savings.

•   Lower energy costs with Atlas Copco’s VSD technology
-   Over 80% of a compressor’s lifecycle cost is taken up by the energy it consumes. Moreover, the generation of compressed air can account for more than 40% of a plant’s total electricity bill. To cut your energy costs, tlas Copco pioneered Variable Speed Drive (VSD) technology in the compressed air industry. VSD leads to major energy savings, while protecting the environment for future generations. Thanks to continual investments in this technology, Atlas Copco offers the widest range of
integrated VSD compressors on the market.

•   Central controllers
-   Having a central controller reduces the average pressure band.It also reduces the operating pressure of your machines.
• By reducing the pressure by 1 bar (or 14.5 psi), your energy usage lowers by 7%.
-   By reducing the pressure by 1 bar (or 14.5 psi) decreases air leakages by 13%.
-   Multiple embedded functions in the Optimizer 4.0 in which pressure, capacity and speed can be regulated. Legend
A = Net pressure
B = Average pressure
C = Min. system pressure

•   Compressed air dryers
-   The correct choice of dryer technology corresponding to the compressed air quality requirements is detrimental 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.

•   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.

•   Quality Assurance
-   The Seller warrants that the ordered goods are manufactured from high-quality materials and standard processes, are brand new and unused, and fully comply with the quality, specifications, and performance stipulated in this Contract. The Seller further warrants that the goods ordered under this Contract, when properly installed, used, and maintained, shall be free from defects for a period of 18 months from the date of shipment from the port of export, or 12 months from the date of commissioning, whichever occurs first.
