Isothermal Processing Vessels

Thermacore’s Isothermal Processing Vessel (IPV) eliminates hot or cold zones on reactor walls, increases product yields and eliminates undesirable by-products. The IPV is an extension of the Isothermal Furnace Liner (IFL) which has been supplied to semiconductor crystal growers and calibration laboratories since 1971. The IFL is an annular liquid metal heat pipe that provides a uniform temperature working environment. Measured spatial temperature variation in an IFL is less than 10 mK and may, in many cases, exceed the sensitivity of available measurement techniques. The IPV combines the IFL heat pipe technology with more advanced vessel design. Small vessels can provide the same temperature uniformity as IFLs, while large vessels maintain temperature within 0.5ºC. The IPV is a custom designed vessel which is fabricated to specific size, configuration, containment and temperature requirements. Size and configuration can vary between small diameter long tube flow reactors and large diameter batch or stirred tank reactors. The isothermalizing operation of the heat pipe is completely passive, requires no user servicing, and operates indefinitely.
