Series 4555 10-20 L Floor Stand Reactors

The Model 4555 and 4557 Reactors with their 5 gallon (18.75 L) capacity are the largest stirred reactors offered by Parr. The 4556 and 4558 Models are similar units with a 10 liter (2.6 gal) volume which falls between the larger 5 gallon design and the smaller 1 and 2 gallon models in the 4550 Series. Vessel styles are offered in a moveable head or fixed head design.

These reactors are available with an FKM O-ring gasket for operating temperatures to 225 °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. A hoist attached to a support column provides a convenient means for lifting the head and cylinder out of the stand and transferring these parts to an opening in the right hand table. Since these vessels are usually equipped with a bottom drain, the cylinder will probably remain in the heater most of the time, but it can be lifted out when necessary.

The support stand for the fixed head design allows the head to remain fixed to the stand while a pneumatic lift allows the lower cylinder to be raised and lowered. When lowered, the cylinder can be slid forward for cleaning and servicing. See the illustration below.

These reactors are generally used for pilot plant or for custom chemical production purposes, usually with a variety of attachments added to the basic units. Special heaters, larger motors, heavier stirrer drives and remote controls appropriate to the size of these reactors have been designed and are available. Other volume, pressure and temperature limits have also been built into these units within the outside dimensions of the 5 gallon system, including a special stirred system rated as high as 5000 psi and 500 °C.

Approximately 7.5 kW of electric power is required to operate these reactors. This is usually too large a load to be drawn from a single phase, 230 volt line. This requirement must therefore be considered carefully when ordering any of these reactors to be sure that the ordered unit is configured to operate on the available power.

Series 4555 - 4558 Ordering Guide

A composite identification number to be used when ordering a reactor can be developed by combining individual symbols from the separate sections.

Example
A 5 gallon, T316SS, with a heavy duty magnetic drive stirrer, 230 V variable speed 1/2 hp motor, 2000 psi gage, serpentine internal cooling coil, manual bottom drain valve, ceramic three-zone heater, electric hoist, 3:1 gear ratio, programmable controller with tachometer, pressure display module and a high temperature cutoff module would be listed as:
