Vessel Heaters

New Style Heater for Non-Stirred Pressure Vessels

New Style Heater for Non-Stirred Pressure Vessels

Electric heaters and automatic temperature controllers are available for most all Parr non-stirred vessels. Some small vessels are generally heated in an oven, bath, furnace or similar general purpose heater. 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 on our Heater Options section. The catalog number of the standard heater designed for each of the non-stirred vessels is listed in the specifications for each vessel.

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.
