Band Heater and Insulating Jacket

Band Heater and Insulating Jacket

Clamp-on, mantle, and ceramic fiber heaters are available for the Series 4790 moveable vessels. Stands with heaters are offered for the fixed head vessels.

The heaters furnished for non-stirred vessels are the same as those furnished for the stirred versions of the same size vessels. A full description of the different types of heaters is found in our Heater Options section. Automatic temperature controllers are available for most all Parr non-stirred vessels.

Custom heaters are also available for these vessels when it is necessary to meet explosion proof requirements, to accommodate installed windows or fittings, or to convert to a welded jacket for steam or oil heating.
