Comparison of vacuum drying oven, blast drying oven and dry heat sterilization box

The vacuum oven, the blast drying oven, and the dry heat sterilization box have a high temperature effect. The cabinet has a sterilization box and an oven. Many people think that the two are the same product, so the three cabinets are mixed and used. In fact, these kinds of cabinets are different. Ovens are sometimes referred to as drying ovens. They are generally divided into vacuum drying ovens and blast drying ovens. The oven we often refer to is a blast drying oven, which has a high temperature because it is only a tool for drying products at high temperatures. Therefore, the temperature is very high, but the high temperature is easy to damage the asbestos net in the box, and it is easy to dye the bacteria. Although the high temperature can kill the bacteria, the safety is still insufficient, so the user who wants to use the oven sterilization is still careful. In order to avoid the asbestos net dyeing bacteria with temperature controller, the sterilization box strictly controls the temperature to avoid repeated bacterial growth in the box and achieve the effect of high temperature sterilization. The specific differences are as follows:

Principle of sterilization
Designed for drying heat-sensitive, easily decomposable and easily oxidizable materials, it can be filled with inert gas inside, and it can be quickly dried for some complex materials.
Through the resistance heating, the temperature inside the box is increased and the air is blown, so that the water is quickly evaporated, thereby achieving the purpose of drying.
High-temperature dry heat oxidizes microorganisms, denatures proteins, and causes concentration of dielectrics to cause poisoning. Among them, the destruction of the cell protoplasm is mainly caused by oxidation, and the microorganism is killed, so that all microorganisms can be killed within a certain heating time.
Application field
Biochemistry, chemical pharmacy, medical and health, agricultural research, environmental protection and other research applications, for powder drying, baking and disinfection and sterilization of various glass containers
Widely used in welding rod industry, dip coating industry, printing industry, optical industry, motor industry, pharmaceutical industry
Dry heat sterilization is mainly used in various fields such as laboratory, medical, pharmaceutical, food processing and so on.
Zui high temperature
200 ° C
300 ° C
250 ° C
Temperature setting reason
With vacuum function, it can achieve the purpose of drying at relatively low temperature
High temperature drying
There is a temperature control system, the high temperature asbestos net is easy to be dyed, so the temperature of the dry heat sterilization box should not be too high.
Sterilization function
Sterilizable but not safe
Sterilizable but not safe
Safe sterilization

Onsite Oxygen Cylinder Filling System

Oxygen Cylinder Filling System


With PSA principles, ETR oxygen cylinder filling system can produce 93%±3% purity oxygen gas from compressed air directly. ETR oxygen cylinder filling system is consisted of Atlas screw air compressor, refrigerated air dryer, compressed air filter, air buffer tank, ETR oxygen plant, oxygen buffer tank, oxygen booster, cylinder filling station and HMI control cabinet.


Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure. With an oxygen booster, the oxygen pressure can be to 150bar and fill in cylinders.
