Caldera 1 is a high-flash point heat transfer fluid designed for applications where the operating temperature must be below the flash point of the fluid. Caldera 1 utilizes pure base fluids and a proprietary blend of advanced additives. This unique formulation increases fluid performance and lifespan by preventing fluid degradation. Caldera 1 has excellent oxidative resistance, making it ideal for both open and closed systems, with and without inert gas blanketing.
