Hoʻokaʻawale ʻia ʻo BT4 ma ke ʻano he hui wela papa B, ʻaʻole ʻoi aku ka nui o ka wela o ka ʻili o nā mea i helu ʻia ma T4 ma mua o 135°C. Loaʻa iā CT4 kahi helu pahū papa C, e like me BT4, and is suitable for environments with hazardous gases such as hydrogen and acetylene, maintaining a maximum surface temperature of 135°C.
Scope of Use
BT4 is suitable for common gases including methane, ethane, ʻaila ʻaila, a hydrogen sulfide.
CT4 encompasses a broader range of less common pahū kinoea, such as hydrogen and water gas at the CT1 level, acetylene at the CT2 level, and carbon disulfide at the CT4 level.
