Hot and cold impact test cases of frost
Cold and hot shock test chamber can complete the alternating high and low temperature test of the natural environment change experiment, is indispensable to many industry test lab equipment, in the long-term process of application of some customers will encounter machine surface frosting condition, the hot and cold impact test box why surface frosting? Destruction: 1, refrigeration air-conditioning evaporator refrigeration air-conditioning evaporator after destruction, boast skillful starting and oxygen from the hot and cold impact test chamber refrigeration, even in the water vapor in the air to the refrigerating unit (along with all the Start the gas pressure in the air conditioning evaporator, atmospheric pressure will be wet strong cold air in the oxygen atoms to machine) Can also cause equipment icing condition. 2 poor air circulation, air conditioning evaporator: hot and cold impact test chamber air conditioning evaporator if poor air circulation, air conditioning refrigerating capacity with fixed can also make air conditioning evaporator frosting or ice, causing bottom pressure is too low, it is very easy to cause frosting condition refrigeration unit shell. 3, refrigerant too much: hot and cold impact test box in normal work condition, refrigeration unit back to the refrigerant vapor absorption instead of liquid, if too much refrigerant and frozen oil filling in refrigerating units into air conditioner expansion valve adjusting flow rate is too large or too much, not entirely in the refrigerants in air conditioning evaporator evaporation, causing wet vapor or liquid refrigerant in the refrigeration unit absorb back, causing the machine appear to freeze. 4, long-term sit idle: refrigeration unit, riser if not boast skillful placed in sealing, not just transferred to drying treatment frostbite on apply, so often boast skillful sit idle frostbite add starting, the moisture in the air will be from outside to inside the machine stand pipe, thus frosting condition. The above explanation is the hot and cold impact test box frosted reason, hope can help you, if you want to learn more about information about hot and cold impact test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!

The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
