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.
