Caldera 19 is a long-lasting food-grade heat transfer fluid and cleaner. It is designed to soften, dissolve, and suspend carbon and varnish deposits within low-temperature heat transfer systems that require a food-grade formulation. This unique formulation can help to restore system performance and efficiency by removing insulating fouling. It is fully-formulated to completely replace an existing fluid, and can be used at temperatures up to 450°F (232°C). Caldera 19 is an ideal solution for preventative maintenance or for cleaning systems that are experiencing minor varnish or carbon deposits.
