Model “ML” Turbomaster Multistage Centrifugal Compressor with Magnetic Bearings Nantes, France May 2000

Terminology â Turbomaster • YORK Multistage Centrifugal Compressor • Series “M” & “ML” â Series “M” • Compressor with Fluid Film Bearings â Series “ML” • Compressor with Magnetic Bearing Package

“M” Strengths â Cost Competitive â Experience â Design Flexibility â Single Mechanical Shaft-seal

“M” Weaknesses â Product Range â API Exceptions • Internal Lube-oil System • Threaded Driveshaft • Non-API Coupling • Single-stage Shaft-seal

In the Beginning. . . â Market Growth â Biggest Opportunity - API Industry

Major API Exceptions â Internal Lube Oil System â Threaded Driveshaft â Non-Conventional Coupling

“ML” - Design Objectives â Compliance with API in key areas • Eliminate major exceptions â Build on Experience â Cost Competitive (API) â Oil-Free Gas Compression â Environmentally Friendly • Zero Fugitive Emissions

Technical Design Challenges â Retain Product Offer Range â Standardization â API Compliance • Bearings (External or Oil-Free) • Driveshaft / Coupling • Shaft Seal

Design Approach â “M” Derivative â Introduce Magnetic Bearings • Partner with World Leader (S 2 M) • Standardized by Model (26, 38, 55)

Merge Two Mature Technologies YORK “M” Compressor S 2 M Actidyne Magnetic Bearings

S 2 M’s Experience â World Leader in Magnetic Bearing Technology â Turbo-molecular Pumps 50, 000+ â High-speed Spindles • Motors • Machine Tools 200+ â Heavy Industrial Duty 218+

Selling Points â API 617 Compliance, per Appendix J • All major exceptions eliminated â Smaller Footprint â No Compressor Lube-Oil System • Pumps, Filters, Coolers, Piping • No Oil Usage â Substantially reduced Maintenance â 75% reduction in Parasitic Losses

Selling Points â Oil-Free Gas Compression â Zero Fugitive Emissions â Single Dry-gas Seal • Half the Flare Leakage of the Competition • Competitors use 2 Seals

Selling Points â State-of-the-Art Diagnostics • Real-time Rotor Position Monitoring • Real-time Rotor Forces Monitoring (5 -Axis) â Programmable Bearing Response • Stiffness & Damping (Phase & Gain) â Automatic Balancing System (ABS) • Reduced Seizmic Vibrations

Return on Investment (ROI) â 4 -6 Years • Parasitic Losses • Oil-Usage • Support Systems • Reduced Maintenance

Applications â Take the “ML” where the “M” can’t go! â Strict API Specifications â Oil-Free Gas Compression

ML - Ready to Go!!
