Product Description
The 50hz Water Cooled Screw Chiller by HuaZhao is designed for large-scale commercial applications, offering efficient, reliable cooling with advanced engineering. This chiller integrates high-efficiency components, including a load evaporator and a sophisticated oil recovery system, making it a standout solution in the Screw Type Chiller Unit category.
High-Efficiency Screw Compressor: Features a semi-closed screw compressor with a 5:6 asymmetric high-efficiency screw rotor for graded or stepless energy regulation. The compressor adjusts automatically based on load changes, optimizing energy use.
Imported High-Quality Components: Ensures durability and minimizes maintenance requirements.
Dual Compressor System: Two compressors can operate independently or together, allowing for flexible cooling capacity based on demand.
User-Friendly Controls: Simple switch controls make operation and maintenance straightforward.
Non-Oxidized Brass Welding: Ensures quality in pipe connections for long-term reliability.
High-Standard Condenser and Evaporator Compliance: Conforms to GB150, GB151, TB/T4750-2003 standards for safe and reliable operation.
Advanced Load Evaporator for Optimal Performance
The 50hz Water Cooled Screw Chiller utilizes a high-efficiency load evaporator with a gravity-type refrigerant distribution system. This setup ensures reliable operation while enhancing evaporation efficiency. The optimized arrangement of the eliminator and evaporator tube contributes to this system's exceptional cooling performance.
Efficient Oil Recovery System
Equipped with a three-stage oil recovery system, this 50hz Water Cooled Screw Chiller recovers oil efficiently during compressor operation. The process prevents impurities from entering the system, maintaining cooling efficiency and ensuring smooth functionality. By consistently recovering and supplying oil, the system prevents oil shortages and extends the operational life of the chiller.
Noise Reduction and Enhanced User Comfort
The 50hz Water Cooled Screw Chiller minimizes turbulence at the intake port to reduce operational noise. This design feature enhances user comfort by preventing disruptive noise levels, making it suitable for environments requiring quieter operation.
Ice Thermal Storage System for Energy Efficiency
HuaZhao's Auto Switch Water Cooled Screw Chiller incorporates an ice thermal storage system. This system produces ice during the night and releases cool air during the day, improving energy efficiency and reducing operational costs. This feature enables a more balanced energy consumption pattern, which can lead to significant cost savings over time.
Modular Construction and Installation Flexibility
Installation is simplified with the modular construction of this 50hz Water Cooled Screw Chiller. Key features include:
Modular Design: This allows the unit to be dismantled and reassembled, making it adaptable to various installation spaces.
Single Point Electrical Connection: Reduces the complexity of installation and maintenance.
Compact Footprint: Saves valuable floor space, making it ideal for commercial facilities with limited space.
