Materials and Structure


Made of cold-rolled steel plate, with rounded corners and integrated graphic design, it has a beautiful appearance.

Box rust-proof

Anti-rust pre-treatment is carried out before spraying, and then electrostatic spraying has excellent anti-rust function.

Inner bladder

SUS304/2B stainless steel plate, the inner tank adopts arc design for easy maintenance.

Insulation Materials

Ultra-fine glass insulation cotton or polyurethane foam.

Motor heat dissipation

The box is particularly deep and combined with axial fan ventilation to greatly improve motor heat dissipation.


Customized stainless steel fin-type electric heating tube, which dissipates heat evenly and has a long service life.

Observation window

Hollow conductive film electric defrost observation window for convenient observation.


The high-quality silicone sealing strip is customized from the mold, and a special defrosting device is installed on the door frame to always keep the sealing strip flexible.


The multi-wing centrifugal impeller is used for powerful air supply circulation to avoid any dead spots and evenly distribute the temperature and humidity in the test area.


Brand new external isolation box humidifier, customized high-quality long-life heating tube, anti-dry burning, easy maintenance.

Water filling port

The front side of the box has an evacuation-type water inlet and has a liquid level display function, which greatly facilitates the equipment to add water.

Waterway system

Automatic water supply for equipment is realized through high-quality water pumps and liquid level controllers. The waterway system uses large-diameter silicone pipes or
PPR pipes for water supply and drainage to prevent waterway blockage.

Cooling System


The original imported French "Taikang" fully enclosed refrigeration compressor is equipped with a compressor condensate water receiving plate.

Refrigeration method
