The Screw Water-Cooled Condensing Unit is a
high-efficiency cooling solution tailored for industrial and commercial
applications. Powered by a twin-screw rotary compressor, it delivers
stable performance with minimal energy consumption. Key features
include:
Advanced Cooling Technology
Utilizes R134a/R513A refrigerants (GWP <600) to meet global
environmental regulations while maintaining superior thermal
conductivity.
Variable-frequency drive (VFD) adjusts cooling output in real-time,
reducing energy waste by up to 30% compared to traditional units.
Robust Construction
Double-layer stainless steel housing with anti-corrosion coating
ensures durability in harsh environments (e.g., marine or chemical
plants).
Modular design allows seamless integration with existing HVAC systems or standalone operation.
Smart Control & Connectivity
PLC-based touchscreen interface with fault self-diagnosis and alarm history logging.
IoT-enabled for remote access via mobile/PC, enabling predictive maintenance and real-time performance tracking.
Wide Application Range
Ideal for large-scale projects: food processing plants, data centers, breweries, and commercial cold storage.
Operates efficiently in temperatures from -10°C to 45°C, adapting to desert, tropical, or cold-storage climates.
Safety & Compliance
Complies with AHRI, CE, and UL standards, ensuring global market eligibility.
Built-in safety protections: high/low-pressure switches, anti-freeze sensors, and overload relays.
Cost-Saving Design
Low noise output (≤75 dB(A)) reduces site-specific noise mitigation costs.
Long service intervals (8,000+ hours between maintenance) minimize downtime.
Why Choose This Unit?
Energy Efficiency: IPLV rating exceeds 5.0, cutting operational costs by 25% over 5 years.
Scalability: Customizable capacities (50kW–1,500kW) to match evolving business needs.
Global Support: 24/7 technical assistance and 2-year warranty (parts replacement included).
The Screw Water-Cooled Condensing Unit integrates twin-screw compressor technology with intelligent controls
and eco-friendly design to deliver industrial-grade cooling performance.
