Fluid Heat Transfer System circulates thermal fluid through process equipment to maintain an even, consistent temperature profile. They consist of tanks, pipes, pumps and heating or cooling sources. Heating sources for fluid heat transfer systems use electricity, natural gas, propane, fuel oil and solar power. These fluid heat transfer systems use national pipe thread connectors. Fluid heat transfer system circulates water, steam, hydrocarbon oils and glycols. They are designed for use in double-walled, closed loop systems and require frequent monitoring to determine whether adjustments or replacements are needed. Fluid heat transfer systems are housed in enclosures that are rated for specific environments. The feature of fluid heat transfer systems includes insulated pipes & casters and small wheels fastened to supporting legs to facilitate movement.
