Ecochillers to Showcase the Lev-Air Oil-Free Centrifugal Chiller at AHR Expo 2026 in Las Vegas
From February 2–4, 2026, Ecochillers will participate in the AHR Expo 2026 in Las Vegas, the world’s largest HVACR marketplace. This year, the company will highlight one of the most advanced technologies in its portfolio: the Lev-Air Ecochillers Oil-Free Centrifugal Chiller, equipped with Copeland oil-free, magnet-free compressors designed for mission-critical cooling.
Built for efficiency, reliability, and long-term performance, the Lev-Air platform represents a major step forward for high-demand sectors such as data centers, industrial processes, hospitals, and large commercial buildings.
Introducing Lev-Air: Top 5 Advantages
1. Ultra-High Efficiency for Critical Loads
The Lev-Air system leverages Copeland oil-free, magnetic-free centrifugal compression and patented Aero-Lift bearing technology, delivering:
- Frictionless rotation with extremely low sound and vibration levels
- Rapid restart capability after a power interruption—essential for uptime-critical environments
- A two-stage impeller design that supports high-lift and low-lift conditions, enabling:
- Superior part-load efficiency
- Extended operating envelope for extreme ambient temperatures
- Higher allowable chilled-water temperatures (19 °F to 75 °F) for heat-recovery and elevated-temperature cooling strategies
Redundancy is built into the architecture: multiple compressors provide higher availability compared to single-compressor designs.
The Lev-Air is available in 1- and 2-circuit configurations, ranging from 80 to 600 tons of cooling capacity, operating with low-GWP refrigerants (R-1234ze, R-515B, R-513A) to support sustainability and regulatory compliance.
2. Magnet-Free Compression Technology
Unlike traditional oil-free chillers that rely on complex magnetic-bearing systems, Lev-Air uses a permanent-magnet motor without magnetic bearings, reducing risks and simplifying long-term operation.
Aero-Lift frictionless bearings improve:
- Mechanical efficiency
- Operating life
- Noise and vibration performance
This makes Lev-Air ideal for data centers and noise-sensitive technical environments.
3. Service Simplicity & Operational Reliability
The Lev-Air design prioritizes uptime and ease of maintenance:
- Fully oil-free architecture eliminates lubrication circuits and prevents efficiency loss due to oil fouling in heat exchangers
- Simplified mechanical layout reduces service time and long-term maintenance cost
- Decoupled VFD architecture allows fast diagnostics and intuitive technician access
- Advanced temperature-control logic ensures:
- Stable operation
- Broad turndown range
- Improved total cost of ownership (TCO)
These features make the Lev-Air a strong fit for continuous-operation facilities such as hospitals, industrial plants, cold-chain processes, and large commercial buildings.
