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

Designed for demanding heating, cooling and process installations. A carefully selected package of corrosion inhibitors and performance additives provides protection against corrosion, helps limit the formation of deposits and supports maintaining cleanliness inside the system. High-quality raw materials help protect the fluid and system components against degradation, supporting long-term and reliable operation.<\/p>\n

Dilution<\/strong>
\nGLITHERM ET CONCENTRATE is not a ready-to-use product. It must be diluted before use. The manufacturer recommends using demineralized water to prepare working solutions.
\nTo achieve the required level of freeze protection, prepare the mixture according to the table below:<\/p>\n\n\n\n\n\n\n\n\n\n
Recommended minimum temperature
