lectric 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 page 102. 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.
Temperature Controller
The Series 4838 Temperature Controller illustrated and
described in Chapter 4 of this catalog are recommended for use
with any of the non-stirred heaters. Special load handling circuitry
must be included with the 4676-4679 vessels to handle their high
power loads. Unless otherwise specified, these controllers are
designed for use with Type J (iron-constantan) thermocouples.
