This series represents a new generation of commercial scroll compressors that integrate advanced fluid dynamics design and intelligent control technologies. Featuring a fully hermetic structure, these compressors are compatible with various environmentally friendly refrigerants and maintain stable operation within an ambient temperature range of -25°C to +55°C. The specially optimized oil management system ensures extended bearing life, while patented sealing technology significantly reduces internal leakage losses.
Core Advantages
Equipped with Enhanced Vapor Injection (EVI) Technology
Key Advantage: This is the standout feature of the series. Via intermediate gas injection, it significantly increases heating capacity and Coefficient of Performance (COP) under extremely low ambient heating conditions. This effectively widens the compressor's operating range, allowing stable and efficient operation even at outdoor temperatures as low as -25°C or below.
Top-Tier Operating Efficiency
Optimized Scrolls: Utilizes high-precision scroll profiles to reduce internal leakage and improve compression efficiency.
High-Efficiency Motor: Matched with optimized Permanent Magnet Synchronous Motors (PMSM) that feature inherently high efficiency. Combined with precise cooling design, this ensures the motor consistently operates within its optimal efficiency range.
Exceptional Reliability
Back-Pressure Control Technology: Automatically adjusts the pressure behind the scrolls to maintain the axial sealing force at an optimal level, ensuring effective sealing while minimizing frictional losses.
Robust Bearing Design: Incorporates large, heavy-duty bearings to ensure stable main shaft operation under high pressure differentials and loads, extending service life.
Valveless Design: The inherent absence of suction and discharge valves in scroll compressors eliminates common system failure points, resulting in smoother operation and lower failure rates.
Low Noise and Vibration
Precise dynamic balancing and an optimized compression process contribute to exceptionally smooth operation. This minimizes vibration transmitted to the piping system and reduces overall noise levels, enhancing comfort in the installation environment.
Wide Operating Range
Thanks to EVI technology and robust mechanical design, this compressor series delivers stable operation, high efficiency, and reliability across a broad spectrum of conditions, from cooling to low-ambient heating.
