Box structural features
The main box is shaped by CNC machine, the modeling is pleasing and nice, and operated by no-reaction handle. It is easy to use.
The interior of the box uses the material of imported stainless steel plate of mirror surface (SUS304), the outside of the box uses plastic coating plate in order to increase the texture and the cleanliness of the appearance.
Large observation window with light make the box bright and the use of embedded heat-tempered glass make the customer have a clear observation at any time.
There is a DIA 50MM test hole at the left of the box, it can connect the test power line or signal line.
Controller
Temperature controller uses all imports touch button instrument, easy to be operated.
When the customer input the data and the test conditions, the controller will lock the functions to avoid human touch and temperature changes.
It has the function of automatic calculation; it can amend the temperature change conditions immediately to make the temperature control more precise and stability.
The customers can choose the printers according to their own demand.
Refrigeration and air path circulatory
The refrigerator uses the “TAI KANG” completely closed compressor made in France.
The refrigeration system uses one unit or dual low-temperature loop system design.
It uses multi-winged blower which can offer cycle and powerful wind, and this wind style can avoid any dead ends, can make the temperature in the region distribute homogeneously.
This Wind Road use wind out and in cycle design, the air pressure and the wind speed are in line with the testing standards, and when open the door, the temperature change to low fast and stable.
Heating system and cooling system can completely work independently. This can raise the efficiency and lower the cost of test, also increase the life expectancy and lower the failure rate.
