USP Approved Food Grade Glycol 99% - 5 Litres
Various industrial & commercial heat transfer systems operate at temperatures outside the normal freezing and boiling points of water.
In order to protect heat transfer systems from freezing, bursting or boiling, a propylene glycol water mixture is used in secondary loop systems. In the case of cooling systems the heat transfer fluid is used to reduce the freezing point below operational temperatures, whereas the heat transfer fluid is used to increase the boiling temperatures in alternative applications.
Propylene Glycol is one such heat transfer fluid commonly used as a secondary cooling & heating, anti-freeze, coolant for beverage cooling / glycol systems, food manufacturing / processing systems, VAC applications, laser cutting, milk & wine production equipment.
