GLITHERM PRO CONCENTRATE<\/strong> is a highly concentrated heat transfer and antifreeze fluid designed to protect installations against freezing. The product is based on high-quality monopropylene glycol (MPG) and is intended for the preparation of working solutions with parameters tailored to the requirements of a specific installation.<\/p>\n

GLITHERM PRO Concentrate is designed for use in heating, cooling and process installations where a working fluid based on monopropylene glycol is required. A carefully selected package of corrosion inhibitors and performance-enhancing additives provides effective corrosion protection, helps reduce the formation of deposits and supports the cleanliness of the system. High-quality raw materials protect both the fluid and installation components against degradation, ensuring long-lasting, reliable and efficient operation.
\nDilution<\/p>\n

GLITHERM PRO CONCENTRATE is not a ready-to-use product. It must be diluted with water before application. The manufacturer recommends using demineralized water to prepare working solutions.<\/p>\n

To achieve the required level of freeze protection, prepare the mixture according to the following table:<\/p>\n\n\n\n\n\n\n\n\n\n
