Product Description

Product Advantages

I. Outstanding Energy Efficiency Performance

High-Efficiency Scroll Technology: Optimized scroll profiles and precision machining achieve over 92% volumetric efficiency, with superior COP across all operating conditions compared to similar products.
Intelligent Unloading Design: Some models feature capacity regulation, enabling stepless adjustment from 10% to 100% and improving part-load efficiency by more than 15%.
Low Starting Current: Starting current is only 2-2.5 times the full-load current, reducing grid impact and lowering system configuration costs.

II. Exceptional Reliability

Dual-Flexible Scroll Design: Patented flexible technology allows for minimal radial and axial float of the scrolls, enhancing resistance to liquid slugging and contaminants.
Reinforced Structural Design:

High-strength cast iron housing with a pressure resistance of up to 4.2 MPa.
Precision-machined crankshaft and bearing system ensure long-term operational stability.
Built-in oil separator with 99.5% efficiency ensures lubrication system reliability.

Multi-Protection System:

INT69 intelligent motor protector for real-time temperature and current monitoring.
High and low-pressure protection switch interfaces.
Optional oil pressure differential protection device.

III. Excellent Operational Quality

Ultra-Low Noise: Operating noise below 65 dB(A), 8-10 dB lower than equivalent piston compressors.
Superior Vibration Control: Dynamic balancing design and damping system keep vibration amplitude <20 μm.
Wide Operating Range:

Evaporation temperature range: -40°C ~ +10°C
Condensation temperature range: +20°C ~ +60°C
Ambient temperature range: -30°C ~ +50°C

IV. Environmental Compatibility

Multi-Refrigerant Compatibility: Fully supports R404A, R448A, R449A, R407C, and other refrigerants.
Easy Eco-Friendly Upgrade: Allows for direct "Drop-in" replacement without system modification.
Low-GWP Options: Supports environmentally friendly refrigerants with GWP < 1500, complying with global environmental regulations.
Lubricant Compatibility: Suitable for various synthetic lubricants including POE, PVE, and PAG.

V. Easy Installation and Maintenance

Compact Design: Standardized installation dimensions save 20-30% of equipment room space.
Reduced Energy Costs: Annual operating energy consumption is 15-25% lower than equivalent piston compressors.
