Why Choose Variable Speed Drive Refrigerant Air Dryer?
There is a fact: In many industrial production, the demand for compressed air is variable. But conventional air compressors have only one speed. Itu dia, they run at full load. Sometimes these demands are less. Thus it will consume and waste a lot of energy.
Similarly, most refrigerant type air dryer systems are inefficient to use. Selain itu, they consume a lot of electricity. So it does not meet the requirements of energy saving. It also greatly increases the cost of use. And the dryer is in the same amount of refrigeration state after opening. The cooling capacity can not be changed. Itu dia, it’s not adjustable. Oleh itu, it greatly consumes electricity.
But the VSD air dryer adopts advanced technology. It can automatically change the speed of the refrigerant compressor. Adapt to the refrigeration capacity demand under different load working conditions. So it can realize energy efficiency improvement.
Advantages of VSD Refrigerant Air Dryer
- Pertama sekali, the compressor realizes soft-start. So improve compressor lifetime. Pada masa yang sama, reduce the impact on the power grid of the factory.
- Kedua, prevent ice blockage of the evaporator at low load. Or prevent liquid compression from causing compressor damage.
- Ketiga, the evaporation temperature realizes PID automatic adjustment. Set the temperature according to actual needs. So VSD air dryer can maximize energy saving.
- Keempat, keep the dew point stable. It supplies high-quality air at a stable, low dew point.
- Akhirnya, the whole refrigerator air dryer system is advanced. Reliable performance and complete functions. Beautiful shape. Selain itu, the operation is simple. And the installation is convenient.
Soalan Lazim
We do not recommend inverter control if more than 200m³/min. Because it is greater than 200m³/min, our refrigerated air dryer system adopts a screw compressor. It has built-in energy regulation. Sebagai tambahan, we also don’t recommend a VSD air dryer when it’s less than 20m³/min. The energy-saving space is relatively small because its compressor power is not large. Selain itu, the VSD control system is relatively expensive.
If DC VSD refrigerated air dryer, it can save energy by 30%. And if AC type, it can save energy by 10~25%.
