Metal tank Series 4675 General Purpose Vessels, 2.6-5 Gal

pressurevertical

The Series 4675 General Purpose Vessels are the largest vessels offered by Parr Instrument Company. Vessel styles are offered in a moveable head or fixed head design. These vessels are available with an FKM O-ring seal for operating temperatures to 225 °C, and FFKM O-ring for temperatures to 300 °C, or with a flat, PTFE gasket for operating temperatures up to 350 °C maximum. In the moveable head design, the vessel is held in a support system which minimizes the physical effort required to handle these heavy components. The hoist is attached to a support column which provides a convenient means for lifting the head and cylinder out of the stand. Vessels equipped with a bottom drain valve will probably remain in the heater most of the time, but can be lifted out when necessary. The fixed head support stand features hinged split-rings that swing to either side allowing the head to remain fixed to the stand while a pneumatic lift allows the cylinder to be raised and lowered. When lowered, the cylinder can be slid forward for cleaning and servicing. These vessels are generally used for pilot plant or for custom chemical production purposes, usually with a variety of attachments added to the basic units.
