90-565 RT COP 5.5 IPLV 8.0 IoT Monitoring Fifty Thousand Hours of Predictable Performance The Chiller That Turns Maintenance Into Data
Product Overview
Sustainable building operations depend on predictable, verifiable equipment performance over decades. The Midea Water Cooled Screw Chiller platform delivers high efficiency combined with long-term performance predictability and data transparency that transforms facility management into intelligent asset stewardship.
The semi-hermetic twin-rotor screw compressor with SKF bearings rated for 50,000+ operating hours provides mechanical reliability that eliminates 2-3 planned compressor overhauls over a 25-year asset life. Combined with stepless capacity regulation, low noise operation, and intelligent monitoring, the platform delivers operational transparency required by modern energy management systems and ESG disclosure frameworks.
Key Features
Predictable Maintenance Intervals
SKF bearings with rated life exceeding 50,000 operating hours
Fewer than one planned compressor intervention over 25-year project lifetime
Bearing traceability certificates for asset-management documentation
Semi-hermetic bolted construction enables field service without full compressor removal
Individual component replacement reduces overhaul cost by 40-60%
Intelligent Monitoring System
7-inch touchscreen controller with real-time operating parameters and trend analysis
Over 20 protective functions continuously monitor system health
Intelligent load control predicts demand changes based on historical data
RS-485 Modbus-RTU interface for real-time BMS integration
Optional Smart Cloud remote monitoring for multi-site fleet management
Stepless Capacity Regulation
Continuous slide-valve modulation from 100% to 12.5% in infinite steps
Maintains leaving water temperature within tight tolerance at every load point
Supports WELL Building Standard thermal-comfort requirements
Part-load noise reduced to 65 dB(A) for installation adjacent to occupied spaces
Flooded Evaporator Efficiency
Flooded evaporator design ensures uniform heat transfer across tube surfaces
Rated COP maintained consistently throughout asset life
Three-stage oil separation with dual oil-return system
Optimized subcooler in condenser circuit captures additional thermal capacity
Platform Flexibility
SHWE fixed-speed series handles predictable baseload at COP 5.534
SCWG variable-speed series tracks load fluctuations with 20-30% part-load efficiency improvement
