Structure Features :


1. SUS304# stainless steel plate is adopted in the test case;There are test rails on both sides of the inner box;The insulation is made of at least 100mm rigid polyurethane foam.The front door of the inner box is connected with high-quality bakelite and fiberglass door frame as heat conduction partition, with excellent low temperature insulation performance;The airtight seal on the door is made of silica gel foam with a certain temperature resistance range.

2. Air supply circulation system: aluminum wind wheel with high and low temperature resistance and multiple blades is adopted uniformly. The upper louver is driven by the motor to supply air, and the lower side returns air.

● insulation material: hard polyurethane foam + glass wool


● Camber door:

1. single door, left open, handle on the right
2. product observation window, three-layer vacuum layers
3. embedded non-reaction plane handle

4. door hinge: SUS# 304

5. light lamp in the test box, 11W

6. silica gel foam strips , 2 pieces

7. electric heating automatic mist removal device 1 set

8. touch frozen scald device, 1set
