BT4 jẹ tito lẹtọ bi Ẹgbẹ iwọn otutu Kilasi B, nibiti iwọn otutu ti o pọju ti awọn ẹrọ T4 ko kọja 135°C. CT4 dimu a Kilasi C bugbamu-ẹri Rating, afiwera BT4, ati pe o dara fun awọn agbegbe pẹlu awọn gaasi ti o lewu gẹgẹbi hydrogen ati acetylene, mimu iwọn otutu oju ti o pọju ti 135°C.
Dopin ti Lilo
BT4 dara fun awọn gaasi ti o wọpọ pẹlu methane, ethane, epo epo, ati hydrogen sulfide.
CT4 yika titobi gbooro ti ko wọpọ bugbamu gaasi, gẹgẹbi hydrogen ati gaasi omi ni ipele CT1, acetylene ni ipele CT2, ati disulfide erogba ni ipele CT4.
