ISO Certificated Professional High And Low Temperature Thermal Shock Environmental Test Chamber

ISO Certificated Professional High And Low Temperature Thermal Shock Environmental Test Chamber

1. Description:

ISO certificated Professional High and Low Temperature Thermal Shock Environmental Test Device with high precision perfect external design, external with double sides cold rolled plate electrostatic powder coated material, internal with SUS#304 high temperature resistant stainless steel. Insulation material adopt fire resistant high strength PU polyurethane foaming thermal insulating material. More than 20% energy saving is achieved thanks to the introducing of Japan & German advanced refrigerator control technology. Control system and control circuit components all with famous brand .

Shock Chamber Works As Follows:

1, low temperature storage tanks: tank temperature is determined by the state of the duct heater, evaporator and the working status of the fan. After the expansion valve throttling the refrigerant flowing into the evaporator in the working chamber, the working chamber of heat absorption and gasification, to reduce the temperature of working chamber; gasified refrigerant is sucked and compressed to a high temperature, high pressure gas into the condenser compressor It is condensed into liquid, and then the screening program, and finally through the expansion valve is throttled after re-entering the working chamber and the evaporator absorbs heat and gasify and then compressed by the compressor suction. This back and forth loop work, so the studio temperature dropped to set temperature requirements

2, high-temperature storage tanks: a central controller temperature sensing signal from the detection instant, and the set temperature signal is compared, the comparison signal obtained by the instrument PID logic circuit output signal to control the solid state relay is turned off or adjusting the heating time ratio output power level, so as to achieve the purpose of automatic temperature control.

3, temperature shock test chamber: the meter automatically controlled high temperature valves, low or high temperatures between the storage chamber switched respectively to form a closed air circulation system and low temperature box or boxes, quickly reached the target temperature tests.

2. Specifications of Thermal Shock Environmental Test Device:

Chamber Structure Way:

Chamber compositions using integrated configuration mode, both located in the upper chamber by a high-temperature chamber, located in the lower part of the low temperature test box, located at the rear of the cabinet and the refrigeration unit on the left rear panel of the electrical control cabinet (system) that composition. This way the box covers an area of small, compact structure, beautiful appearance, chiller cabinets placed in a separate unit, the refrigeration unit to reduce vibration during operation, the impact of noise on the chamber, while facilitating devices and maintenance of the unit, electrical control panel on the left panel of the chamber in order to run the operation.

Notes

1. If the high-temp exposure range lower limit + 60°C is required or the low temp exposure range lower limit -60°C, please select the “ambient-temperature exposure” option

2. If the temp fluctuation need to below ±1.8°C please select the “Low temp fluctuation package”

3. Temperature heat-up/pull down time are applicable only during independent chamber operation

4. If the automatically operated sliding door required, please select the “Automatically door package”

5. Air-cooled condenser / Water-cooled condenser both available

6. Apply on water-cooled condenser only

Operation and settings simplified by the use of a touch-screen LCD display (instructions displayed on-screen). At-aglance confirmation of test patterns, test area temperatures, temperature cycles, and trend graph displays.

Buy thermal shock chambers should pay attention to five areas:

the impact of temperature, load test, reset time, defrost time, sensor placement
