Three Zone Thermal Shock Test Chamber / High Low Temperature Testing Equipment


1. Description:

Environmental Test Chamber Degree in an instant by a high temperature and extremely low temperature environment can tolerate continuous, that is, in the shortest time test chemical changes or physical damage due to its thermal expansion and contraction caused. Suitable objects include metal, plastic, rubber, electronics ... and other materials can be used as a basis for improvement of their products or reference


2.Thermal Shock Chambers of the Structure:
. the chamber configuration mode: 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 electrical control cabinet composed of (system). 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.

. the outer wall of the housing materials: high-quality carbon steel plate, look for color electrostatic spray disposal.

. high and low temperature impact test chamber insulation materials: high-quality ultra-fine glass fiber cotton.

. the inner wall of the housing material: Imported SUS304 stainless steel, corrosion-resistant, easy to clean.

. laboratory lighting installations: moisture-proof lights.

4.Shock Chamber Works As Follows:

. 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 throttling, re-entered the studio evaporator endothermic gasification and then compressed by the compressor suction


. 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.


. 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 test


The Air Control:
Forced circulation ventilation, balanced temperature method (BTC). This method not only refers to the case of the cooling system for continuous operation, the control system according to the temperature set point of the heater to control the output of the results by automatically calculating PID output, and ultimately achieve a dynamic equilibrium.




. 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


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


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


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


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


. Apply on water-cooled condenser only

Radiator Thermal Shock Test the refrigeration unit (condenser) should be regularly maintained and kept clean. Sticky dust the condenser and the compressor will generate false alarms tripped high pressure switch, the condenser should be regularly monthly maintenance, use a vacuum cleaner to use after a hard brush dust suction power or attachment of the condenser cooling mesh brushes or high pressure gas nozzle blown clean of dust.


Packaging & Shipping

Simulation Animatronic Customer Triceratops are covered with air bubble film before put them into the wooden case, which not only has good shock absorption, impact resistance, heat sealing and also has the advantages of nontoxic, odorless, moisture corrosion, good transparency etc.
