Hanbell RC2-580B-Z RC2-580B-W Air Cooled AC Screw Compressor for Restaurant
Product Description
Multinational Patents of High-Efficiency Screw Rotors
The RC2-580B utilizes a patented 5:6 high-efficiency screw rotor profile developed to optimize compression efficiency across modern refrigerants. Manufactured using high-precision CNC machining centers, rotor milling, and grinding machines, the rotor geometry undergoes rigorous ISO 9001 quality controls and ZEISS 3D coordinate inspection to deliver maximal displacement, excellent volumetric efficiency, and quiet, low-vibration performance.
High Efficiency Motor & Integrated Suction Cooling
Equipped with a 3-phase, 2-pole squirrel-cage induction motor built from premium grade low-loss core steel. The motor features specialized internal cooling slots and guide vanes that direct cold suction refrigerant gas straight through the motor housing, ensuring optimal motor heat dissipation and peak running efficiency even under severe HVAC system workloads.
Precise Capacity Control Mechanism
Designed for dynamic load regulation, the compressor's hydraulic slide valve is positioned directly within the compression chamber. Actuated via differential pressure using pressurized oil injected from the sump and regulated by external solenoid valves, it supports either 4-stage stepped control (35%-50%-75%-100%) or continuous stepless capacity control (35%-100%) to match varying thermal requirements.
Application Areas
Large Commercial Central HVAC: Engineered specifically as a reliable ac screw compressor for water-cooled and air-cooled liquid chillers in commercial office complexes, airports, and shopping malls.
Industrial Process Cooling: Provides steady, precise thermal control for high-capacity industrial liquid chillers operating under shifting manufacturing loads.
Cold Storage Logistics: Suitable for large-scale agricultural precooling facilities and medium-to-low temperature logistics centers.

Frequently Asked Questions
Q1: How does the RC2-580B protect against motor overheating during continuous high-load summer operation?
A: Motor cooling relies on cold suction refrigerant gas guided through internal slots and guide vanes across the motor casing. Additionally, embedded PTC thermistors continuously monitor coil and discharge gas temperatures, triggering protective modules if limits are exceeded.
Q2: Can this compressor handle extreme part-load conditions without causing excessive chiller cycling?
A: Yes, the hydraulic slide valve allows for continuous stepless regulation down to 35% capacity, smoothly adjusting compressor output to match low-demand hours without frequent on/off cycling.
Q3: What options are available if my system requires supplemental oil cooling under high pressure ratios?
A: The compressor body includes dedicated external oil cooler connection ports alongside liquid injection ports to easily integrate auxiliary cooling loops for high-compression operation.
Q4: What is the delivery lead time for commercial B2B orders?
A: In-stock sample units dispatch within 3 business days, while volume commercial manufacturing contracts are typically completed in 10 to 15 working days.
Q5: Can Ruifujie supply OEM branded compressors and customized technical nameplates?
A: Yes, Ruifujie provides comprehensive OEM/ODM solutions, including custom multi-language metal nameplates, tailored motor voltage wiring, and private labeling.
