The Hermetic Water-Cooled Condensing Unit represents the pinnacle of sealed-system refrigeration technology,
designed for applications demanding zero refrigerant leakage and minimal
maintenance. By integrating hermetic compressors with advanced
water-cooled heat exchangers, it delivers uninterrupted cooling for
supermarkets, breweries, and pharmaceutical facilities.
Technical Superiority
Hermetic Seal Technology: Compressors are welded into a single housing, eliminating shaft seals and reducing refrigerant leak risk to <0.1% annually.
Dual-Stage Cooling: Optional economizer circuits enhance capacity by 15% at high ambient temperatures.
Self-Diagnostic PLC: Monitors 30+ parameters (e.g., oil pressure, discharge temperature) and triggers alerts via email/SMS.
Energy & Environmental Performance
Variable Speed Drives: Condenser fans adjust speed based on load, achieving IEER values up to 5.0.
Low GWP Refrigerants: R513A option reduces global warming impact by 55% vs. traditional R134a.
Applications
Food Retail: Precision cooling for medium-temperature storage (2℃ to 8℃) and frozen displays (-25℃).
Process Cooling: Ideal for breweries, dairy plants, and chemical synthesis requiring stable temperature control.
Design & Durability
C5-M Corrosion Resistance: Electrogalvanized steel panels with marine-grade epoxy coating resist salt spray for 2,000+ hours.
Seismic-Rated Frame: Meets IBC 2021 standards for installation in earthquake-prone regions.
Smart Integration
BMS Compatibility: Open Modbus TCP/IP protocol allows seamless integration with Johnson Controls, Siemens, or Honeywell BMS.
Cloud Monitoring: Optional IoT gateway enables remote performance tracking via web dashboard or mobile app.
Maintenance & Safety
Design & Engineering
Hermetic Compressor Core: Dual-screw or reciprocating compressors with permanent magnet motors, achieving 98.5% volumetric efficiency.
Multi-Pass Condenser: Stainless steel
tubes with helical fins increase heat exchange surface area by 40%,
enabling 15% smaller footprint vs. conventional designs.
Adaptive Oil Management: Oil separator with 99.98% efficiency and level-sensing probes prevent compressor damage during low-load operation.
Performance Features
Ultra-Wide Capacity Control: 25–100% stepless capacity modulation via VFD drives, ideal for fluctuating loads in breweries or data centers.
Subcooling Circuit: Liquid-line subcooling improves system efficiency by 8–12%, especially critical in high-ambient conditions.
Surge Protection: Proprietary algorithm prevents compressor surge during rapid load changes, extending motor life by 30%.
Control System
PLC Logic Controller: Pre-loaded with 50+ application-specific programs (e.g., brewery fermentation, vaccine storage).
Cybersecurity: Encrypted Modbus TCP/IP communication with role-based access control (RBAC) for BMS integration.
Pre-Installation Checklist
Verify concrete foundation meets 6,000kg/m² load capacity (including 20% safety margin).
Confirm cooling tower flow rate matches (1.8x nominal flow for systems >50HP).
Install dedicated power circuit with C-type breakers (6kA short-circuit rating).
Installation Procedures
Pipe Alignment: Use vibration-damped hangers
for vertical suction lines to prevent thermal fatigue. Maintain ≥300mm
clearance from electrical panels.
