Product Details:
Industrial oil-free screw air compressor, 3.5–13 bar.
An outstanding oil-free screw air compressor.
ZR and ZT oil-free air compressors are engineered with innovative, in-house technologies, embodying years of R&D expertise.
ZR/ZT Screw Compressor Instructions
Our oil-free screw compressors are designed to deliver low life-cycle costs and provide high-quality air that meets industry standards.
ZR and ZT compressors are used in industries that require high‑standard compressed air quality, such as food and beverage, pharmaceuticals, automotive, medical, textile, power generation, chemical, battery, and many other sectors.
The difference between ZR and ZT
Choosing our ZR or ZT compressors ensures that your processes and products are protected by clean air, free from contamination originating from the compressor.
What’s the difference? The ZR is water-cooled, while the ZT is air-cooled. With a pressure range of 3.5 to 13 bar, it features screw‑type technology that delivers superior air quality and delivers significant energy savings.
The ZT 75 VSD+ Premium air-cooled oil-free screw compressor is equipped with an integrated iMD dryer.
Integrated Solution
A compact, all-in-one, high-quality air solution.
ZR and ZT oil-free screw air compressors are available as Full Feature units, which include:
• Integrated dryer that saves installation space
• Variable-speed drives (VSDs) that can reduce energy costs.
Technical Advantages – Screw Compressors
Outstanding oil-free air
Class 0 series compressors, compliant with ISO 8573‑1, help you reliably mitigate the risks of contamination, unsafe products, or losses due to operational disruptions.
Energy savings of up to 35%
Efficient design. Save even more energy with our variable-speed drives (VSD), energy recovery features, and zero‑energy MD dryers.
Quick & Easy Setup
A plug-and-play complete unit that integrates a dryer, a variable-speed drive (VSD), and an energy recovery system. It ensures easy installation, low cost, and rapid startup.
Higher reliability
Six decades of innovation and experience, backed by an extensive customer base. Long-lasting performance is ensured through Atlas Copco‑designed premium components: stainless steel coolers, AGMA A5/DIN 5 gears, and a new inverter‑driven system. Each machine undergoes rigorous testing to guarantee dependable quality.
Global Positioning – Localization Services
Our after-sales product portfolio can flexibly meet your needs, ensuring that your compressed air equipment delivers exceptionally high availability and reliability at the lowest possible operating costs.
Meets the higher quality standards of the food and beverage industry.
Our oil-free production facilities have been certified to ISO 22000. This food safety management system applies to all of our Z‑type Class 0 oil-free screw air compressors, as well as their associated dryers and filters.
Designed specifically for energy efficiency
The components of our ZR/ZT oil-free screw air compressor series are all meticulously designed in-house. This minimizes losses and pressure drops to exceptionally low levels, contributing to the development of highly efficient complete compressors.
Our oil-free compressors are also Class 0‑certified, delivering exceptionally high air purity at a very low total cost of ownership. Our screw‑type technology ensures reliable, high‑efficiency performance.
Variable-Speed Drive Energy-Saving Statistics
Energy costs account for more than 80% of a compressor’s life-cycle costs.
The cost of producing compressed air accounts for more than 40% of a plant’s total electricity expenses. To help you reduce your energy costs, we have implemented variable-speed drive (VSD) technology in the compressed-air industry.
Atlas Copco’s VSD technology automatically adjusts motor speed to precisely match air demand, delivering energy savings of up to 35%.
Energy recovery
Transform your compressor into an energy source. Our water-cooled screw compressors can be equipped with energy recovery systems, helping you achieve your low-carbon economic goals.
Up to 94% of the electrical energy is converted into compression heat. Without energy recovery, this thermal energy would be lost to the atmosphere. Our energy recovery system utilizes this compression heat to produce water suitable for sanitary purposes, space heating, or industrial processes.
Smart technology helps you save energy.
Our compressor monitoring system employs advanced control algorithms to achieve energy savings. Our delayed secondary shutdown feature leverages air demand data to halt compressor operation whenever feasible. A dual-pressure band can reduce system pressure during off-peak periods such as weekends and evening shifts.
Our Elektronikon® controller is the compressor’s brain, collecting data to deliver outstanding energy efficiency.
Monitor your system
Understanding the status of your compressed air system is crucial. With Elektronikon®, you can easily connect the controller to mobile devices, such as tablets and smartphones.
Our SMARTLINK smart connectivity system enables mobile monitoring over a secure network. This monitoring solution not only helps you save costs but also prevents equipment failures and production losses.
