Nitrogen purging oven, can be simply understood as nitrogen-filled oven. Widely used in electronics industry (silicone rubber, spraying, semiconductor, LCM、LCD、LED、MLCC、TFT、 precision ceramics, quartz oscillator), PCB、PE、 electrolytic capacitance, rubber and plastic keyboard, computer, etc.; motor, communication, hardware, chemical, sports equipment, printing, pharmaceutical, shoe industry, auto parts and other industries baking, drying, preheating and tempering, aging and other purposes. Characteristics of nitrogen-filled oven: 1, The oven can heat, therefore can dry, glue solidifies, dehumidifies and so on. 2. The oven can provide nitrogen (inert gas) to drive out the air in the oven, so that it can dry, solidify, dehumidify and so on in the dust-free and anaerobic (oxygen content below 100 ppm) environment, avoid the oxygen in the air to destroy the product, affect the product quality.

I. Nitrogen-filled oven (drying oven) 1. Generally, the requirements for an anaerobic environment are not strict 2.The plate and welding process of nitrogen-filled oven is simple and economical. 3.The nitrogen-filled oven is cheaper than the anaerobic oven. 4.The sealing of nitrogen-filled oven is not fully sealed, the process and cost limit its sealing, the door adopts single seal, the motor shaft has no seal and no full welding, etc. II. Anaerobic oven (anaerobic oven) 1.Anaerobic oven, can achieve ≤ oxygen content of 50 ppm, due to its sealing and nitrogen distribution, air duct design, exhaust location design, are through digital-analog simulation design. 2.The oxygen-free oven door is a double-sealing structure, which can achieve the function of fast oxygen reduction and rapid cooling. 3.Adaptable to industrial demand 4.The weight of the anaerobic oven is heavier and the price is higher than that of the nitrogen-filled oven. EJER nitrogen-filled oven is used to bake more medicinal materials, while anaerobic oven (anaerobic oven) is used in semiconductor industry and LED touch panel industry. Customers can decide which oven to choose according to the product process requirements.

Benchtop temperature cycle test chamber is mainly applied for electrical, electronic products, components, and materials in the process of storage, transportation and use in high and low temperature environment, as well as temperature gradient test, but also for electronic components stress screening test, and the core component of the equipment is compressor, it will directly affect the performance of the equipment, many customers will consult how to maintain the equipment? 1. the voltage in the workplace of the high and low temperature test chamber must be stable. If the voltage is unstable, the current may be too large or too small. If the equipment works in this environment for a long time, it will bring great damage to the compressor. It is recommended to use a voltage stabilizer to connect the equipment. 2. the working environment of the high and low temperature test chamber should be well ventilated and dust free. In order to ensure that the compressor surface of the equipment is clean, the equipment should be placed in a dust-free space without use for a long time. 3. the high and low temperature test chamber in the process of use, do not start the compressor too frequently, and the compressor start time interval of at least 15 minutes.

Introduction The industrial oven is composed of cold rolled steel and stainless steel, in addition, the body is strengthened, the exterior surface is power coating, the insulation part is filled with aluminum silicate fiber to form a reliable insulation layer. The industrial oven is widely used to dry/bake/cure all kinds of industrial materials and is a general drying equipment. Working principle The temperature is controlled by the connection between the digital display controller and the temperature sensor. The hot air circulation system is divided into horizontal type and vertical type. By accurate calculation, the air source is driven by the operation of the air supply motor to drive the air fan through the electric heater, send the hot air to the air duct and enter the oven studio, and the air suction duct after use is used as the air source for recycling and heating. This can effectively improve temperature uniformity. If the oven door is switched in use, the air supply circulation system can quickly restore the operating state temperature value. Oven structure The industrial oven is an inside and outside double layer structure, the shell is cold rolled steel, the inside and outside double layer shell is filled with fiber material. The fiber material used in industrial oven is mostly aluminum silicate, which can play the role of heat preservation and form a reliable insulation layer. Industrial ovens are equipped with hot air circulation system and temperature measurement and control system. When the industrial oven is working, the operator obtains the temperature value inside the industrial oven through the instrument and temperature sensor, and operates through the control system. Compared with the common heat dissipation heating mode, the hot air circulation heating mode of industrial oven has better gas fluidity and can speed up the drying speed of materials in industrial oven. The hot air circulation system of industrial oven is composed of air supply motor, air wheel and electric heater. The air supply motor drives the air wheel to send out the cold air, and the cold air passes through the heating equipment to carry the heat energy and enters the oven studio of the industrial oven through the air duct. The hot air circulation system of industrial oven is helpful to improve the uniformity of air temperature. In the process of transporting materials from the switch box door of industrial oven, the temperature value will be changed. The uniformity of hot air circulation system is beneficial to restore the temperature value of working state in fast speed.
