Products Description
The use of inverter compressors combined together with refrigeration systems is subject to extensive research by leading global manufacturers. When the inverter compressor starts, it runs at high frequency for rapid cooling. Once the room temperature reaches the setting, it switches to low frequency and low speed to maintain the environment with minimal energy consumption and low temperature fluctuations, significantly extending the compressor's lifespan.
Main Features
- Faster cooling speed with small temperature fluctuation range
- Efficient energy saving, significantly reducing system energy costs
- Increased compressor reliability due to fewer startups
- Low noise operation thanks to extremely high system flexibility
- Extremely low vibration phenomena
