תיאור
Choosing the high temperature option (HT) boosts the maximum temperature to 500 °C, but de-rates the MAWP to 2000 psi (138 bar). Standard Mini vessels can be converted to high temperature vessels (500 °C max temperature and 2000 psi MAWP) by chaing the head assembly (contains cone connections, high temperature valves, and grafoil gasket) replacing the heater with a ceramic fiber heater and replacing the split ring. Contact Parr for details.
Although internal and external space is limited on these small vessels, custom ports and fittings are available.
All vessels in this series can also be easily converted
from one size to another by simply substituting a longer or shorter cylinder with the corresponding internal fittings and heaters.
Clamp-on or mantle heaters are available for the
Series 4760-4777 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.
