ZRZT 15-55 (VSD)
Oil-free rotary tooth air compressors ZR & ZT
Features
The Atlas Copco ZR/ZT 15-55 VSD series consists of premium oil-free rotary tooth air compressors engineered to deliver high-quality, pure air with maximum energy savings.
Core Features
- 100% Oil-Free Air: Certified to ISO 8573-1 CLASS 0 standards, eliminating any risk of oil contamination in sensitive production environments like pharmaceuticals, food processing, and electronics manufacturing.
- Variable Speed Drive Technology: The integrated VSD frequency converter continuously adjusts the motor speed to match actual air demand, lowering energy consumption by up to 35% by eliminating unload losses and transition wastes.
- Rotary Tooth Technology: Uses a symmetrical, dynamically balanced two-stage compression design that maximizes free air delivery and delivers long-term performance without needing element venting.
- Advanced Monitoring: Features the Elektronikon controller with a high-resolution color display and intuitive navigation to regulate system pressure within a tight band and track machine health.
- Quiet Operation: Built with a sound-insulated canopy and a vertical cooler layout to lower noise from the fan, motor, and compression elements, allowing installation directly in the workspace.
- Space-Saving Footprint: Designed as a compact, all-in-one package containing the drive motor, cooling systems, and moisture management systems to save valuable plant floor space.
Available Configurations and Component Highlights
- ZR vs. ZT Models: The ZR versions are water-cooled models, while the ZT variants are fully air-cooled units that dissipate heat efficiently through cast teeth without requiring a cooling water system.
- Full Feature Concept: Offers optional built-in heat of compression or refrigerant dryers to supply dry air with guaranteed dew points while minimizing pressure drops and standalone footprint.
- Dual Independent Seals: Features two independent floating oil and air seals separated by a neutral buffer zone to strictly block oil from penetrating the compression chamber.
- High-Efficiency Air Filter: Uses a robust air inlet filtration system with up to 99.9% coarse separation to provide maximum reliability and lengthen service intervals.
Benefits
The Atlas Copco ZR/ZT 15-55 VSD series delivers significant operational advantages by combining certified oil-free purity with smart energy management.
Operational and Financial Benefits
- Massive Energy Savings: Variable Speed Drive technology slashes energy costs by up to 35% by precisely matching air production to your real-time demand.
- Zero Contamination Risk: Certified ISO 8573-1 Class 0 air ensures absolute purity, protecting your end products from oil spoilage and safeguarding your brand reputation.
- Lower Total Cost of Ownership: High-efficiency rotary tooth elements reduce mechanical wear, resulting in longer service intervals and fewer unplanned production stops.
- Reduced Installation Expenses: The compact, all-in-one “Full Feature” design includes integrated dryers and filters, removing the need for external equipment and complex piping layouts.
- Enhanced Sustainable Footprint: Lower power consumption directly reduces your facility’s carbon footprint, helping you meet strict corporate environmental goals.
- Flexible Point-of-Use Installation: Exceptional sound insulation and low vibration levels allow you to place the compressor directly on the workshop floor, saving expensive dedicated plant space.
Engineering and Maintenance Advantages
- Optimized Plant Uptime: The intelligent Elektronikon controller offers early warnings, remote monitoring, and automated safety shutdowns to prevent unexpected breakdowns.
- Eliminated Idle Losses: Standard fixed-speed compressors waste energy when running unloaded; this VSD system eliminates those idle periods entirely.
- Stable Network Pressure: The continuous speed adjustment maintains a highly stable system pressure, preventing pressure drops that can disrupt sensitive manufacturing tools.
- Plug-and-Play Maintenance: Symmetrical component layouts provide quick access to all service panels, drastically lowering routine maintenance turnaround times.
