Isothermal Furnace Liners

For uniform isothermal environments — with temperature control that surpasses any conventional thermal control technique — laboratories and engineers turn to Aavid Thermacore isothermal furnace liners (IFL).

Isothermal furnace liner heat pipeIsothermal furnace liners from Aavid Thermacore save time and energy while maximizing productivity, by achieving isothermal wall temperature and the superior temperature uniformity required in diverse applications such as semiconductor crystal growth, thermocouple and temperature calibration, vapor deposition, black body radiators, concentrated solar receivers and more. With no moving parts, the IFL is simple to install, provides design flexibility and is extremely reliable and cost-effective. Unlike probes, the IFL does not depend on heat transfer paths connecting to surrounding walls or the outside environment.

isothermal furnace liner heat pipeIn most applications, Aavid Thermacore IFLs provide a single uniform temperature zone using a single heater and controller. For multiple, individually-controlled zones or step changes in temperature profile, two or more IFLs may be used in series. Temperature adjustment is a simple one-step process and frequent profile measurements are not necessary.

IFLs are well suited to for process tubes and laboratory furnaces in chemical processing and research applications.

Standard IFLs for operation to 1,600°C are available in a range of sizes to fit conventional furnace bores for horizontal or vertical application. Custom IFLs can be fabricated for sub-ambient and cryogenic operation. The size and geometry of the IFL can be customized to any application.
