• Variable Speed Drive
- A Variable Speed Drive (VSD) compressor automatically adjusts its motor speed to the air demand. Applications have a varying air demand. That is why Atlas Copco pioneered the Variable Speed Drive (VSD) technology for compressors to make sure that yoursystem gets the right amount of air.
• Save Energy with a VSD
- Adding one or more VSD machines to your compressed air installation will greatly improve the energy efficiency of the complete system, with energy savings easily up to 35%.
• Integrated ID & IMD Dryers
- Integrating our ID or iMD dryers ensures optimum efficiency for the combination of compressor and dryer. iMD
heat of compression rotary drum dryers will even give you a dew point suppression of 40°C without loss of compressed purge air nor extra energy input for a blower or heater. This dryer is regenerated with the heat of compression. If you need dry
air, this is definitely the most efficient dryer solution, infinitely better than any alternative.
• Designed for efficiency Oil-free tooth element
- Oil free tooth technology remains very competitive among the dry compression technologies for this power range in terms of
efficiency. They make ZT/ZR 15-55 the best choice in this power range of oil free compressors.
• IE3/IE4 Motors: Super Premium Efficiency
- On our fixed speed machines, introduction of IE3/IE4 class motors will save extra energy, every hour the machine runs. With machines typically running 4000 to 8000 hours per year, again a major contributor to efficiency and energy savings.
• Multiple Machine Control
- Any installation with 3 or more machines will benefit from a central controller. This can be our optional built in control algorithm EQ4i/ EQ6i, our advanced sequencer, Equalizer 4.0 or our advanced controller, Optimizer 4.0. Each have their benefits for their typical target installations. But one thing they all have in common: they will control your installation in
a more efficient way than the individual machines with individual settings can.
• Oil-free Tooth Element
- Our oil free tooth elements have a supreme track record of proven reliability and durability. Combined with competitive efficiencies, they make the ZT/ZR range the best choice in this power range of oil free compressors.
• Advance touch screen monitoring system
- The next-generation Elektronikon® operating system offers a great variety of control and monitoring features that allow you to
increase your compressor’s efficiency and reliability thanks to the many embedded advanced control algorithms.
• Mechanical Drive System
- Our recently introduced super premium efficiency IE4 class motor, combined with a gear box design that has proven its extreme reliability, this ZT/ZR range is equipped with a highly efficient and reliable mechanical drive system.
• Optimal control
- On our VSD variants, we are using our in-house designed highly efficient NEOS frequency converters. Neos frequency converters are built into a cubicle that ensures stable operation up to 50°C/122°F. We combine the NEOS frequency converter with electric motors that have been specifically designed for VSD use, also on low motor speeds with attention for motor and
compressor cooling. All Atlas Copco VSD compressors are tested and certified for Electro Magnetic Compliance. Compressor
operation does not influence external sources and vice versa. Our VSD compressors can range between 30-100% of the maximum capacity (turndown 70%). Between minimum and maximum motor speed, the motor can run on every speed (there are no resonance frequencies that need to be avoided), so that stable net pressure and energy savings are ensured.
• Cooling
- ZT VSD compressors are provided with an air-cooled oil cooler, an intercooler and an aftercooler. An electric motor driven fan
generates the cooling air. ZR compressors have a water-cooled oil cooler, an intercooler and an aftercooler. Newly introduced Tube and Shell type coolers ensure sturdy performance. The cooling system includes three parallel circuits:
• Plug & play package
- Our ZR/ZT are designed for easy installation and maintenance. No unnecessary interlinking of extra components, so no extra risks for downtime.
• Compact design
- Low footprint and easy installation.
• Soundproof design
- The ZR/ZT compressor comes with a sound insulated canopy. No separate compressor room is required. It allows for installation in most working environments.
• Ease of maintenance
- Components in the compressor are strategically placed for ease of access.
• 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.
• 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.
• 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.
• Ventilation
- Compressors generate heat. Adequate evacuation of this heat will ensure favorable working conditions for compressors and dryers alike.
• 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.
• 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.
• Options
- With the ZT/ZR, Atlas Copco provides an all-in-one standard package incorporating the latest technology in a built-to-last design. To further optimize your ZT/ZR’s performance or to simply tailor it to your specific production environment, optional features are available.
• 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.
