Biotemp is commonly chosen where environmental risk from leaks and fire performance matter. It is a natural ester fluid designed to be readily biodegradable and to reduce the impact of spills compared with conventional mineral oil. Natural esters also typically have higher fire point than mineral oil, which helps in locations with strict fire safety requirements such as near buildings, forests, waterways, or critical infrastructure. These fluids can support longer insulation life in some regimes due to better moisture tolerance, but they must still meet applicable specifications and maintenance practices.
