Explosion-proof Walk-In High and Low Temperature Humidity Test Chamber 8.36m³ 

Spray-coated galvanized color steel plate--temperature stress resistant insulation material--SUS304 stainless steel plate composite assembly plate.

Among them:

Spray-coated galvanized color steel plate (external) thickness 0.8mm, color is standard warehouse gray.

SUS304 stainless steel plate (inner) thickness 1.0 mm.

The bottom plate uses 2.0mm embossed anti-skid plate.

The thickness of the temperature stress resistant insulation material layer: 100mm.

The load-bearing capacity of the test room floor: 600kg/m2 (uniform load)

Centrifugal fan: 4 pcs

Heater, evaporator (also dehumidifier), water supply and drainage port, dry bulb temperature sensor.

Wet heat type also includes: humidifier, dry burn preventer, and additional dryer. Guaranteed continuous working time of -10℃~-30℃≥14 days.

When the smoke alarm is on, the smoke exhaust is turned on, and the maximum air exchange rate is 850m³/h

(1) Smoke sensor:

There is one smoke sensor on each of the upper and lower layers of the temperature chamber. After an abnormal alarm, the power supply of the equipment is cut off and the fire extinguishing device is activated; it is required to be arranged outside the temperature chamber.

(2) After detecting an abnormal signal (the signal threshold and form are defined by Party A and implemented by Party B), spraying is realized in the chamber, without damaging samples and equipment, extinguishing the fire within 30 seconds, and no re-ignition within 30 minutes after power failure;

(3) Fire extinguishing device: Fire water is connected. Spraying fire extinguishing is realized in the chamber.

(4) The fire communication protocol is open. When a fire occurs, the equipment alarm simultaneously feeds back the switch signal to the charging and discharging equipment, and the charging and discharging equipment stops the test through logical judgment.

Manual fire extinguishing

A set of explosion-proof pressure relief vents is set on the top of the equipment, with a size of 300mm×500mm. When the internal pressure of the box is ≥0.104MPa, the pressure relief vent will open automatically.
