product structure

Inner box material: SUS #304 mirror stainless steel plate

Outer box material: SUS #304 stainless steel plate or cold-rolled steel plate with paint

Insulation material: rigid Polyurethane foam + glass wool

Cooling System:

Refrigeration system and compressor: In order to ensure the cooling rate and minimum temperature requirements of the test chamber, the test chamber adopts a binary cascade air-cooled refrigeration system composed of a set of imported compressors.

The compressor adopts the fully hermetic "Taikang" compressor imported from France or the semi-hermetic "Bitzer" compressor imported from Germany.
