LIYI Stand Alone 3 Zone Temperature Cycling Chamber Electronic Products Test
Machine introduction:
Programmable 3- Zone Temperature Cycling Cool and Heat Thermal Shock Testing Chamber for Electronic Products makes the product under low and high temperature, and accelerates the failure caused by repeated temperature changes under normal operating conditions of items.During cold and hot shock tests, the transition between extreme temperatures was very rapid, exceeding 15℃ per minute.Alternatively, the temperature cycle uses a slower rate of high and low temperature change, exceeding 5℃ per minute.

Application objects, including metal, plastic, rubber, electronics and other materials can be used as a basis to improve their products or reference.
Remark: We can achieve 1000cycles defrosting once, it is very ideal, the shorter the defrosting interval, the worse the airtightness of the device!

Automatic adjustment of energy consumption output of the refrigeration system. |
| 7.Refrigeration Technology |
Nitrogen welding, two-stage rotary vane vacuum pump, ensure that the internal cooling system clean and reliable. water tray located at the bottom of the compressor to ensure condensate water drain through pipe freely at the rear of the chamber. |
Since the cold chamber need huge cooling capacity for shocking, the chamber’s cooling mode is often designed as air-cooled or water-cooled.
Air-cooled type need installation environment:
The room must be equipped with exhauster and air conditioner to make sure heat dissipation timely.
It’s applied to small power products and cool areas.
Water-cooled type need installation conditions:
The customer must prepare water pipe and water tower (located outside) accordingly.
The water must be pure, or it will block the pipes and result in some maintenance trouble with time going.
It’s often applied to large system with the features of better heat dissipation, longer service time, low noise but slightly higher price if count the fee of water tower and water pipes.
