Isobar® Heat Pipe
• Large amounts of energy can be rapidly transferred.
• Heatpipes are intrinsically Isothermal.
• Redistribution of localized energy inputs.
• Intuitive response to energy deficits and surpluses.
• Requires no direct power or physical connections.
• Sealed System.

Isomandrel in induction heated curing applications
• The induction heating coil are situated proximate to the mandrel permitting unimpeded mandrel rotation.
• Induction heating is relatively instantaneous and intense.
• Significant thermal energy per unit time can be provided.
• The Induction coil heats a small portion of the O.D. of the mandrel and not the composite winding.
