Product Overview:
It is mainly used in industries such as electronic and electrical components, automation parts, communication components, automotive parts, metals, and chemical materials. It tests the repeated tensile force of materials under high and low temperatures, as well as the chemical changes or physical damages caused by thermal expansion and contraction of the products, in order to confirm the product quality. Structural design: It is generally divided into three parts: the high-temperature zone, the low-temperature zone, and the test zone. The test samples are placed in the test zone. The inner box material is usually SUS304 stainless steel, which has the characteristics of corrosion resistance and strong cold and heat fatigue resistance; the outer box is made of steel plate painted or stainless steel. The box body uses high-density polyurethane foam insulation material or silicic acid aluminum insulation cotton, etc., to reduce heat loss.
Product Features:
Temperature performance: The temperature range is typically from -70℃ to +200℃, which can cover the testing requirements of the vast majority of products. The high-temperature zone can be rapidly heated up, the low-temperature zone can be rapidly cooled down, and the temperature change rate can be adjusted, usually ranging from 5℃/min to 40℃/min. The moving time of the thermal shock mechanism is generally within 10 seconds, the temperature recovery time is usually within 5 minutes, which can meet the relevant test specifications. Control system: Equipped with a large-sized color LCD touch-screen microcomputer control system, the operation is simple and easy to understand. It can set the number of cycles, defrosting times, and has an automatic (manual) defrosting function. It can also be scheduled to start, automatically pre-cool and preheat in advance. At the same time, it has RS-232 or RS-485 communication interfaces, which can be connected to a computer for remote control. • Refrigeration and heating systems: The refrigeration system often uses imported fully enclosed compressors from France such as Trane and Germany such as Bierzer, supporting cascade refrigeration, using R404A and other environmentally friendly refrigerants. The heating system generally uses nickel-chromium alloy electric heating wires or stainless steel finned heat dissipation tubes for heating, through centrifugal fans to achieve forced air circulation to achieve uniform heating. • Safety protection: There are various protection devices, such as zero-crossing current-limiting power controller, heating airlock protection switch, compressor overpressure protection switch, compressor overload and overcurrent protection switch, phase loss protection switch, etc., to ensure the safe operation of the equipment. The test object is completely stationary. It can be connected to the test hole with negative bus wiring.
The oxygen supply method can avoid the harm caused by the presence of the oxygen source during use. (Note: The oxygen supply increases the amount of oxygen absorbed by the lungs and reduces the amount of oxygen inhaled.) The working mode is centralized, and the control system adopts a color easy-to-understand display control panel. The operation is simple and easy to operate. The temperature control accuracy is high, and all are PID automatic calculation control.
It can automatically detect the position, and the opening or closing range is high or low. It has pre-heating assistance function. It can set the number of cycles and automatically defrost (can also have the function of automatic defrost without additional defrosting function). It can be selected to have two or three slots or ring inserts. The specifications are clear.
