The specially formulated heat transfer fluids developed by BPI have been proven to be the best heating mediums available. They heat quickly and evenly, maintain the high temperatures needed for your tints, and are non-toxic. They help preserve the interior of your base tank and protect your heating element as their evaporation factor is almost nil. It is unwise to make any substitutions, which may corrode, evaporate quickly, or release toxic vapors.
