Shenhai Explosion-Proof
The CT6 model surpasses the AT3 in both gas and temperature classifications, thereby offering a significantly higher explosion-proof rating. CT6 represents the highest standard in explosion-proof classifications.
| Gas classification/temperature group | T1 | T2 | T3 | T4 | T5 | T6 |
|---|---|---|---|---|---|---|
| IIA | Formaldehyde, toluene, methyl ester, acetylene, propane, acetone, acrylic acid, benzene, styrene, carbon monoxide, ethyl acetate, acetic acid, chlorobenzene, methyl acetate, chlorine | Methanol, ethanol, ethylbenzene, propanol, propylene, butanol, butyl acetate, amyl acetate, cyclopentane | Pentane, pentanol, hexane, ethanol, heptane, octane, cyclohexanol, turpentine, naphtha, petroleum (including gasoline), fuel oil, pentanol tetrachloride | Acetaldehyde, trimethylamine | Ethyl nitrite | |
| IIB | Propylene ester, dimethyl ether | Butadiene, epoxy propane, ethylene | Dimethyl ether, acrolein, hydrogen carbide | |||
| IIC | Hydrogen, water gas | Acetylene | Carbon disulfide | Ethyl nitrate |
Group A includes gases like propane, while Group C covers hydrogen and acetylene.
For temperature classifications, T3 allows for temperatures up to 200°C, encompassing fuels such as gasoline, kerosene, and diesel. In contrast, T6 limits temperatures to 85°C, applicable to substances like ethyl nitrite.
