Water Cooled Screw Chiller 90-565 RT COP 5.5 50000-Hr Bearing Life
Fifty thousand hours between overhauls - the chiller that respects your maintenance schedule
Product Overview
For facility managers responsible for water-cooled chiller plants, compressor maintenance represents both the heart of the system and the source of significant maintenance anxiety. Compressor overhauls are typically the most expensive maintenance event in a chiller's lifecycle, costing 30-50% of the original chiller price and requiring specialist technicians, crane lifts, and weeks of lead time for replacement parts.
The Midea Water Cooled Screw Chiller platform - including the SHWE series (R134a, fixed-speed, 94.6-565.6 RT, COP 5.534, IPLV 8.085) and SCWG series (R513A, variable-speed + R134a, fixed-speed, 90-550+ RT) - was specifically designed to make compressor overhaul a rare, planned event rather than an emergency that disrupts maintenance budgets.
The key innovation is the SKF bearing system rated for 50,000+ operating hours. In typical commercial applications running 4,000-5,000 hours annually, this translates to 10-12 years of operation before the first planned compressor intervention. Over a 25-year asset life, facilities experience fewer than two compressor-related maintenance events compared to 3-4 events with conventional bearing systems.
Key Features
SKF 50,000-Hour Bearings
Plan maintenance by the decade with SKF bearing systems rated for 50,000+ operating hours under standard conditions. Each bearing includes traceability certificates for asset management audits and warranty administration.
  • 10-12 years of service before first planned intervention
  • Fewer than two compressor maintenance events over 25-year asset life
  • Semi-hermetic bolted construction enables on-site bearing replacement
  • Individual component replacement reduces overhaul costs by 40-60%
7-Inch Touchscreen Controller
Complete plant intelligence at a glance with real-time parameter monitoring and trend history graphs that reveal developing issues before they trigger alarms.
  • Real-time display of all operating parameters with trend history
  • Over 20 protective functions with severity-based alarm categorization
  • Plain-language response guidance for maintenance teams
  • Eliminates need for specialist diagnostic equipment
Stepless Capacity Modulation
Continuous slide-valve regulation adjusts output from 100% to 12.5% in infinite steps, eliminating temperature cycling that generates tenant comfort complaints.
  • Narrow temperature tolerance at every load point
  • Reduces complaint-related maintenance work orders by 30-50%
  • Part-load noise reduced to 65 dB(A)
  • Protects process-sensitive environments
Flooded Evaporator Design
Maintains consistent performance year after year with uniform heat transfer across tube surfaces and three-stage oil separation preventing performance degradation.
  • Maintains rated COP 5.534 throughout service life
  • No gradual efficiency degradation from oil fouling
  • Eliminates periodic chemical cleaning requirements
  • Predictable energy consumption from year one through year fifteen
Mixed Baseload + Peaking Strategy
Optimized for real operating profiles with fixed-speed units handling baseload at maximum COP and variable-speed units tracking load fluctuations with superior part-load efficiency.
  • Automatic real-time management of baseload/peaking split
  • Plant always operates near most efficient point
  • No manual sequencing or loading calculations required
  • Identical service architecture and spare-parts compatibility
On-Site Serviceability
Every serviceable component accessible in the mechanical room without compressor removal, transforming maintenance from multi-week crises to scheduled service events.
  • 40-60% cost savings compared to factory overhauls
  • Standard tools and commonly available seals handle most procedures
  • No compressor removal, workshop transport, or crane rental required
  • Significant lifecycle cost savings exceed incremental equipment cost
