Water Cooled Screw Chiller 90-565 RT COP 5.5 IPLV 8.0

SKF 50000hr Life Engineered to Outlast Its Own Financial Model - The 50000 Hour Chiller

Product Overview

Water-cooled chiller economics follow a fundamentally different logic from air-cooled systems. While the condenser water loop adds infrastructure cost upfront, the resulting improvement in heat-rejection efficiency dramatically lowers per-kilowatt operating expense throughout the asset lifecycle. The Midea Water Cooled Screw Chiller platform maximizes this economic advantage over decades of continuous operation through two complementary series covering 90 to 565+ RT.

The SHWE series operates on R134a at fixed speed, delivering COP 5.534 and IPLV 8.085 - figures that place it at the top of water-cooled screw efficiency rankings. It targets applications with stable, predictable baseload including hospitals running 24/7, government buildings with consistent occupancy, and industrial processes requiring continuous cooling at steady-state conditions.

The SCWG series adds R513A variable-frequency and R134a fixed-speed configurations covering 90-550+ RT, serving facilities where load fluctuates significantly and inverter-driven part-load efficiency provides the highest return on investment.

Key Features

Semi-Hermetic Twin-Rotor Screw Compressor

Asymmetric 5-to-6 rotor profile machined to micrometre precision for optimal compression efficiency
Semi-hermetic bolted construction enables field service without full compressor removal
Individual rotor, bearing, and shaft-seal replacement reduces overhaul cost by 40-60% versus hermetic designs
No suction or discharge valves eliminates common reciprocating compressor failure points
Continuous scroll compression produces minimal vibration transmitted to building structure
Closed motor design cooled by suction refrigerant - no motor cooling air required in plant room

SKF Bearing System Rated for 50,000+ Operating Hours

SKF-brand bearings with rated life exceeding 50,000 operating hours under standard conditions
Eliminates 2-3 compressor overhauls over a 25-year project lifetime
Avoided maintenance cost of $80,000-150,000 per chiller over full asset life
Bearing traceability certificates provided with every unit for asset-management documentation
Validated through accelerated life testing and field data from thousands of installed units globally
Difference-pressure oil supply system eliminates need for external oil pump

Stepless Capacity Regulation from 100% to 12.5%

Continuous slide-valve modulation from 100% to 12.5% in infinite steps - no fixed staging
Leaving water temperature maintained within tight tolerance at every load point
Eliminates cyclic losses from discrete-step capacity control strategies
Part-load noise reduced to 65 dB(A) - installable adjacent to occupied spaces
Full-load noise typically 75-80 dB(A) at 1 metre, within commercial plant-room norms
Smooth capacity transitions protect downstream processes from temperature fluctuation

Flooded Evaporator with Advanced Liquid Distribution

Flooded evaporator submerges tube bundle in liquid refrigerant for uniform heat transfer
Every tube surface participates actively - no underutilized areas as in DX designs
Integrated liquid distribution plate ensures even refrigerant circulation across the bundle
Optimized subcooler in condenser circuit captures additional thermal capacity
More compact heat exchanger footprint for same rated capacity versus DX alternatives
Three-stage oil separation with dual oil-return system and Venturi ejector

R513A Variable-Speed and R134a Fixed-Speed Platform Flexibility

SHWE series: R134a fixed-speed, COP 5.534, IPLV 8.085 for stable baseload applications
SCWG series: R513A variable-speed + R134a fixed-speed for fluctuating-load facilities
Variable-speed option delivers 20-30% part-load efficiency improvement over fixed-speed models
R513A GWP of 573 provides F-Gas phase-down compliance for EU and forward-looking markets
Both series share identical service architecture, spare-parts compatibility, and control interfaces
Platform flexibility allows mixed installations with fixed-speed baseload and variable-speed peaking

Intelligent Monitoring and Protection System

7-inch touchscreen controller displays all operating parameters in real time
Over 20 protective functions including freeze, phase-sequence, pressure, and thermal protection
RS-485 Modbus-RTU communication enables direct BMS integration
Optional Smart Cloud remote monitoring supports multi-site portfolio management
Intelligent load control predicts real-time demand changes based on historical operating data
Smart fault response system categorizes alarms by severity and guides maintenance response
