KSAD cold drying machine

　　Selection Guide for Freezing Drying Machine

　　The correct selection of a freeze dryer must take into account five factors: the actual flow rate, pressure, temperature of compressed air, as well as the ambient temperature and required pressure dew point temperature. The processing capacity of the refrigerated dryer Qs=Qa × C1 × C2. where Qa is the actual flow rate of compressed air.

　　Principle of Cold Drying Machine

　　Cold drying machine is based on the principle of refrigeration dehumidification, which forces compressed air through an evaporator for heat exchange and cooling, allowing gaseous water and oil in the compressed air to undergo equal pressure cooling, condense into liquid water and oil, and carry dust. It is then discharged from the system through an automatic drain to obtain clean compressed air.

　　Characteristics of Cold Drying Machine

　　The refrigeration compressor adopts high-temperature fully enclosed and enclosed refrigeration compressors from companies such as PERFORMER, KERRY, COPELAND, MANEURO, and Haili in France. It operates stably, has low noise, reliable performance, and has a long energy-saving lifespan.

　　The heat exchanger and condenser are made of high-quality and high-efficiency threaded pipes, with high heat transfer coefficient, resulting in small size and compact structure. Simplified materials can be made of stainless steel or galvanized carbon steel to avoid secondary pollution of compressed air.

　　The refrigeration control components are all equipped with advanced Danish DANFOSS, American ALCO, and Polish refrigeration components, with excellent performance. They have the throttling and pressure reducing function of the power expansion valve, the energy regulation function of the hot gas bypass valve, the oil content protection function of the oil separator and the high and low pressure protection function of the refrigerant.

　　The gas-liquid separation adopts a gas-liquid separator that combines cyclone separation and stainless steel wire mesh mist capture, which has a thorough gas-liquid separation effect, avoids secondary evaporation of water, and plays an important role in ensuring the drying effect of the cold dryer. It is much better than a cyclone separator, and at the same time, it has lower operating costs than a filtered gas-liquid separator, with a higher performance to price ratio.

　　The design structure is reasonable, easy to maintain, and has a box shaped appearance, which is beautiful and generous.

　　No basic installation.

　　Example:

　　The inlet air pressure of the refrigerated dryer is 0.7MPa, the inlet air temperature of the refrigerated dryer is 40 ° C, and the ambient temperature is 40 ° C. The actual flow rate Qa of compressed air is 10Nm3/min, and the required pressure dew point+20 ° C. Therefore, the quantity Qs at the refrigerated dryer is Qa x C1 x C2. According to Table 1 and Table 2. C1=0.80. C2=1.22. and Qs=9.76. The KSAD-10SF specification should be selected as the most suitable.
