First, the blower drying box desktop and vertical distinction:
1, vertical blower drying box using rectangular floor-standing structure, is generally placed directly on the test room floor. Test instrumentation is generally in the upper side of the drying box, easy to operate. Vertical blast drying box using the United States original imported fan, vertical, vertical forced convection, so that the temperature inside the chamber is uniform, according to national standards (± 2%) because the duct structure is more special, the fan at the bottom of the box, natural air convection. Vertical blast drying box power and structure is larger, suitable for a variety of products or materials and electrical, instrumentation, instrumentation, components, electronics, electricians and automotive, aviation, communications, plastics, machinery, chemical, food, chemicals, hardware tools in constant temperature environmental conditions for drying and a variety of constant temperature adaptability test.
2, desktop air blower drying box horizontal box structure, the instrumentation in the box on the right, the box is small and easy to test mobile. In industrial and mining enterprises, colleges and universities, biopharmaceuticals, food processing, scientific research, medical units and various laboratories for non-flammable and explosive and non-volatile substances for drying, baking, melting wax and disinfection, sterilization. Benchtop blast drying oven using hot air circulation system consists of fans and special air ducts that can operate continuously at high temperatures, the temperature inside the chamber is uniform, widely used in the drying of glassware, experimental samples, food, chemical substances, thermal denaturation, thermal hardness, thermal softening, moisture exclusion, bioengineering, utensils, appliances, dry heat sterilization, drying and aging of electronic components.
Two, electric constant temperature blower drying box and high temperature blower drying box to distinguish:
1, high temperature blower drying box using imported more than one high-power fan, dual-airway heat circulation system, stainless steel high-temperature electric heaters through the wind cycle, rapid heating of the working chamber. The working chamber adopts mirror stainless steel and super heat preservation high quality cotton, can make the temperature of the box body up to 600 ℃ high temperature, widely used in high temperature drying of special materials, workpiece heating installation, material high temperature test, chemical raw materials reaction processing, ultra-high-temperature oven, higher working temperature, high-temperature drying of special materials, workpiece heating heat treatment, high-temperature test of materials, and so on.
2, electric constant temperature blast drying oven using air conditioning, forced internal circulation ventilation, balanced temperature regulation. Drying box using PT100 platinum resistance temperature sensor, digital temperature regulator (see below) for temperature control, sensitive temperature control, easy to operate, reliable performance, digital direct display of the working temperature, intuitive easy to read. The drying box is widely used for baking melting, drying or other heating of specimens, the maximum working temperature of 300 ℃, the temperature accuracy of up to ± 0.1 ℃. Electrothermal constant temperature blast drying box is suitable for determining the moisture in coal, drying items, drying heat treatment and other heating purposes.
