🔧2、 Structure and Design Features
Box material and insulation
shell1.5mm high-quality cold-rolled steel plate, surface treated with electrostatic spraying for rust prevention.
inner linerSUS304 mirror stainless steel plate, corrosion-resistant and easy to clean.
insulation layer: 100mm thick high-density polyurethane rigid foam or glass fiber cotton, saving energy by more than 30%.
Key component optimization
observation window280 × 350mm multi-layer insulated tempered glass with built-in electric heating and anti frost design, ensuring full visibility throughout the test.
Air duct systemLow temperature resistant long shaft motor+multi wing centrifugal wind turbine, forced three-dimensional turbulent circulation, ensuring temperature uniformity.
test holeThe left side comes standard with Ø 50mm lead holes, high and low temperature resistant sealing design, and supports power on testing.
Safety and Convenience
Mobile Design4 PU movable casters are configured at the bottom, supporting fixation and flexible displacement.
pressure balanceTop pressure relief device, automatically adjusts the pressure difference inside and outside the box to prevent deformation of the door seal.
