MagBoost Magnetic Levitation Centrifugal Chiller
230-3,000RT Oil-Free Platform with Aerospace-Grade Compression Technology for Commercial Centrifugal Applications
Overview
The MagBoost series introduces bearing-free compression technology to commercial and industrial cooling systems, completely eliminating mechanical contact in the rotating assembly. This innovative suspension architecture removes oil entirely from the refrigeration circuit, delivering significant benefits for maintenance scheduling and efficiency across full-load to part-load operating conditions.
Advanced two-stage compression incorporates aerodynamic principles developed through aerospace engineering, providing measurable efficiency improvements throughout the entire operating range. Permanent magnet synchronous motor technology complements the compression system across all capacity levels, while microchannel heat exchanger technology reduces required refrigerant inventory while enhancing heat transfer performance.
Precision position monitoring at 20kHz maintains rotor stability within micrometer tolerances. Emergency power capability ensures graceful shutdown during supply interruptions, with passive backup bearings providing mechanical security. The system supports cooling water supply temperatures as low as 12°C, with single-compressor operation extending down to 10% of rated output.
Performance testing demonstrates COP values reaching 6.774, with IPLV values up to 12.03. Comprehensive warranty coverage includes five years for the complete unit assembly and ten years for the magnetic bearing assembly. Design provisions accommodate future refrigerant transitions to R1234ze, R513A, or R515B as regulatory requirements evolve.
