SMARDT Oil-Free Inverter Centrifugal Chiller
Description
Magnetic suspension bearing, inverter direct-drive, efficient two-stage centrifugal compressor, lower cost throughout the full lifecycle.
Features
- High Efficiency & Energy Saving Oil-free magnetic bearing compressor, zero friction, zero lubricant, zero attenuation. Unit IPLV as high as 12, 40% more efficient than conventional screw/centrifugal chillers.
-Stability and Reliability
Fast unit restart in 20s to guarantee processing requirements for air-side devices and reduce configuration for energy storage tank.
No complicate oil system; up to 30-year stable and reliable operations
-High Availability
Stable running even with 2% load, no need for configurations for small cooling capacity.
Less chillers can save equipment room space, make the cold water system simple and easy to construct, and less initial investment is required.
-Convenient Installation and Easy to Use
SMARDT supports both modular and split types to meet various demands on site.
Unit parts can be maintained in 2 hours. Single compressor maintenance without unit stop is supported
Technical Specification
- Advanced Oil-Free Magnetic Bearing Compressor
Zero friction, zero lubricant, zero attenuation.
48000RPM permanent-magnet synchronous inverter motor, with efficiency up to 98%.
High-speed direct drive design, no step-up gearbox is required, thus avoiding energy loss caused by gear transmission.
High-speed direct drive two-stage impeller with smaller size to achieve more compact structure.
- “PONY EXPRESS” Design
Large VTT compressor and small TT compressor are used together to prevent efficiency trough period.
The unit can maintain efficient and stable operation with 2%-100% load.
- Advanced Oil-Free Magnetic Bearing Compressor
Zero friction, zero lubricant, zero attenuation.
48000RPM permanent-magnet synchronous inverter motor, with efficiency up to 98%.
High-speed direct drive design, no step-up gearbox is required, thus avoiding energy loss caused by gear transmission.
High-speed direct drive two-stage impeller with smaller size to achieve more compact structure.
- "SMART LIFT" Function
This can ensure efficient and stable operation of the unit under low ambient temperature and high chilled water temperature, with no need for the complicated cooling water bypass design.
Unit efficiency is further improved by taking advantage of the low cooling water temperature. COP at partial load can reach 32.1.
