3. Equipment Structure

Serial Number Project Name Technical Specifications
3.1 Box Structure Integrated (left/right/front/rear) frame structure, welded with national standard channel steel. The equipment is sturdy and durable, featuring minimal operational vibration, low noise, and ensuring overall reliability and safety performance.
3.2 Inner Box Material Made of 1.0mm thick SUS #304 stainless steel; fully welded as a whole to ensure the sealing performance of the inner box. The bottom is reinforced for a load-bearing capacity of ≥300KG average load.
3.3 Outer Box Material Made of 1.2MM thick cold-rolled steel plate with double-sided spraying treatment, in blue-white color. (Customizable according to customer requirements, with color boards or color numbers provided)
3.4 Thermal Insulation Material The thermal insulation layer is 100MM thick, made of fire-resistant high-strength rigid polyurethane foam thermal insulation material, with a thermal insulation coefficient of <0.0212 kcal/m∙hr.
3.5 Box Door Structure Single-door design. A double-layer silicone rubber sealing strip is used between the door and the box, which is resistant to high and low temperatures and anti-aging to ensure sealing performance. The door frame and door edge are equipped with anti-condensation and anti-frost electric heating devices to prevent condensate on the box surface.
3.6 Test Observation Window Equipped with 1 vacuum multi-layer explosion-proof glass viewing window, designed with anti-fog and anti-frost functions: the periphery of the viewing window uses film-coated heating for anti-frosting to prevent water vapor condensation. A safe high-brightness energy-saving lighting lamp is installed above the observation window (manually controlled by a direct switch).
3.7 Air Path Components Adopts a circulating fan and motor, aluminum extended shaft, and a high/low temperature-resistant aluminum multi-wing circulating fan structure to achieve forced convection vertical diffusion circulation. Adjustable air outlet for the air inlet.
3.8 Sample Shelf Made of stainless steel, equipped with 2 sets of brackets, which can be freely adjusted up and down (customizable according to customer requirements).
3.9 Test Hole One test hole with a diameter of 50mm is reserved on the left side of the box, and one set of silicone plug + sealing cover is additionally provided.
3.10 Three-Color Light Installed three-color light: green for operation, yellow for stop, and red for fault.
3.11 Drainage Trough Drainage troughs are provided around the box to facilitate the discharge of condensate and prevent internal water accumulation.
3.12 Balance Hole A pressure balance hole is installed inside the box to balance the pressure inside and outside the box.
3.13 Universal Wheels Universal wheels are installed at the bottom of the equipment to facilitate relocation, movement, and positioning.
