Other

Ensure no liquid or solid water is present inside the working chamber.

BoxStructureFeatures

Structural method

The inner lining corners feature large chamfer design, and the work chamber is fully welded for enhanced sealing performance.

Composition of Materials

Outer Material: 1.5MM cold-rolled steel plate with electrostatic powder coating, color as shown in the picture.

Inner Wall Material: 1.2mm, Mirror Finish SUS304 Stainless Steel

Surface finish: III D, all internal interfaces are polished

Insulating Materials: Natural mineral wool, thickness not less than 80mm, excellent thermal insulation properties.

Sealing Materials: Fluorinated rubber, etc., VOC-free organic compounds

Pipe connections: Materials for the intake section in contact with the interior compartment must not be organic.

All materials inside the box do not adsorb or release formaldehyde and VOCs.

Recirculating fan unit

Choose all-metal blade axial flow fans with oil-free bearings; install 2 fan exhausts at the bottom back side (the wind plate is lower, with the diameter edge 1500MM from the bottom), exhaust through a porous plate at the top, the recirculating air is easy to disassemble and clean; the sharp section is rounded to prevent injury and is easy to clean.

Studio

The work cabin is integrally molded with seamless welding, the weld surfaces are polished for a smooth finish, ensuring no blind spots or gaps.

Hatch door

Hinge door, multi-point clamping, adjustable gap.

The design features a double-door opening, ensuring no air exchange between the inner chamber and the outer environment. There is a heating element between the door and the glass to prevent condensation from forming when the internal temperature of the box is higher than the external temperature.

Observation window

Inner door centered position, with 3-layer hollow glass, featuring a heating element and anti-condensation function.

Sample hole

On the left side of the equipment, there are 3 air sample collection points inside the cabin. The sampling ports are made of finely processed brass material, and the sampling pipes are connected to the inner stainless steel panel through stainless steel pipes, without touching the jacket layer in between, thereby not being affected by the air in the jacket layer. Charcoal or TENAX sampling tubes can be directly inserted into the test cabin for sampling. To avoid external air affecting the sampling port, a 6x9 rubber tube can be matched and connected, or a sampling tube with a diameter of 0.8mm can be directly inserted, and the sampling port can be sealed with a spiral seal.

Luminous lamp

Utilizing LED light strips, designed on the observation cabin exterior inner door, for easy observation of samples inside.

Air Conditioning

Supply of gas

Electromagnetic compression air pump, with an independent power plug design

Temperature Control

The temperature control method of the air sleeve, which is an air sleeve between the inner and outer casings, is equipped with cooling coils and heating pipes.

Humidity Control

Humidity control is achieved through a dry-wet mixing method, blending air dried by an oil-free air compressor with moist air to reach the set humidity level.

Intake Volume Control

Flow meter needle valve, intake through porous tube in the working chamber for even release

Air inlet purification

The air pump is followed by a series connection (activated carbon), and a molecular sieve filtration unit.

Other: The test chamber is designed for water wash-down, with easy-to-remove air duct baffles.

Hatch coaming and piping associated with intake and exhaust ducts, as well as water towers and internal materials, are all non-organic to prevent contamination.

2. Place the fans at the very back, two fans, positioned near the bottom.

3. The vent hole diameter of the airfoil is reduced to approximately 2-3mm.

4. The vent holes at the bottom are modified to a louver-like shape, making the internal compressor invisible from the outside, while the ventilation holes on the other three sides are very small.

5. Electrical loads are isolated from each other.

6. The case is well-filled with material, especially near the door, ensuring minimal noise when the door opens and closes.

2. Sampling hole3Individual units feature flanged connections at the inner and outer diameter junctions.
