The Relatherm S-FG (5 GL) – Silicone Heat Transfer Fluid is a food-grade (silicone-based) heat transfer fluid designed for use in temperature-controlled heating and cooling circuits in botanical extraction and distillation equipment. Relatherm S-FG provides excellent thermal stability across a wide operating temperature range, making it suitable for both chilling and high-temperature heating circuits in Huber, Julabo, and other circulator brands used with VTA and UIC distillation systems. The 5-gallon container provides a full system charge for most lab-scale distillation setups.
