Structure

Chamber structure

The test room adopts imported PVC polyethylene board (Taiwan Nanya), thickness 8mm, durable temperature at 85℃.
The sealing cover of the test chamber adopts imported acrylic plate with a thickness of 6mm
The reagent replenishment bottle adopts a hidden type with water level detection, which is easy to clean and not easy to break.
The pressure air barrel adopts SUS304# stainless steel high-pressure resistant barrel with the best heat preservation effect.
The test material rack adopts a flat indexing rack, which can adjust the angle at will to fall and receive fog on all sides, and
place more samples
The test chamber is sealed by water to ensure that the corrosive gas in the box does not leak
The control box and the test box are integrated, and the left and right structure is easy to operate
The water and electricity separation structure is adopted to effectively prevent water from entering the electrical control box
and damaging the accessories

Lid

The sealing cover of the test chamber is made of imported acrylic board with a thickness of 6mm, made into a 1000-angle sealing
cover at the top, which can effectively prevent condensation and water droplets on the surface of the sample from affecting the
test results

Control Panel

Imported touch screen temperature and humidity controller, pressure gauge, power switch.

Power distribution control cabinet

Water solenoid valve, spray solenoid valve, demister solenoid valve, switchboard, cooling fan, compressor, condenser, humidifier,
overtemperature protector, air saturation pressure tank, spray regulating valve

Heating system

Air heating method, titanium alloy heating tube, 316L corrosion-resistant electric heating plate, P.I.D control heating to achieve
temperature balance

Water replenishment system

1. Water storage tank and pressure bucket water replenishment: manual and automatic water replenishment control systems, which can
be connected to the tap water pipe to automatically control water replenishment or manual water replenishment, which is convenient
to use;
Note: If the tap water has too much impurities or has acidity and alkalinity, a filter should be installed at the water inlet
2.Potion replenishment: adopt hidden large water tank, manual replenishment method

Drainage system
