Structure of high and low temperature alternating damp heat test chamber

The equipment is mainly composed of box, heating system, refrigeration system, air circulation system and control system.

The design of the test box is perfect. It is processed and formed by NC machine tool and adopts non reaction handle. The operation of the test box is easy.

The door seal adopts refined silicone rubber, so there is no aging and hardening under high and low temperature.

The inner tank is made of imported SUS304 stainless steel plate, and the shell is made of A3 plate with plastic spraying treatment, which is more smooth and beautiful.

The insulation system uses ultra-fine glass fiber or hard polyurethane foam to fill the insulation area to ensure the internal temperature of the box.

The independent heating and cooling system makes the equipment more effective in heating and cooling. The cooling system is a fully automatic control and safety protection coordination system.

Multi wing strong air supply circulation is adopted to avoid any dead angle and make the temperature distribution in the test area uniform.

Air circulation air outlet and return design, wind pressure and wind speed meet the test standards, and can make the temperature return time faster at the moment of opening the door.

Original imported Korean "temi880" programmable temperature and humidity controller (5.7-inch 16 bit true color touch screen); Chinese menu operation mode, memory program group 120 groups, each program group contains 1200 program segments, all cycles, up to 999 cycles

Characteristics of high and low temperature alternating damp heat test chamber:

The test box is applicable to the adaptability test of instrument materials, electricians, electronic products, household appliances, auto and motorcycle parts, chemical coatings, aerospace products and other related product parts during storage, transportation and use in the environment of high and low temperature, humidity and heat. The test equipment is mainly applicable to the reliability test of industrial products with constant and alternating humidity and heat. It carries out environmental simulation test on the physical and other relevant characteristics of the products to judge whether the performance of the products can still meet the predetermined requirements, so as to facilitate product design, improvement, identification and delivery inspection.

The technical parameters of all standard models of high and low temperature alternating damp heat test chamber are as follows:
