PARR 4550 Serisi Reaktörler (1 ve 2 Galon)

4551 Floor Stand Reactor, 1 Gallon, with Bottom Drain Valve,
and 4843 Temperature Controller

4554 Reactor, Fixed Head, 2 Gallon Vessel

Series 4550 1 and 2 Gallon Reactors

These 4550 Reactors extend the size range of the 4530 Series to 1 and 2 gallon (3.75 and 7.5 liter) sizes, providing excellent facilities for pilot plant studies. They can be furnished with either a self-sealing O- ring closure for working temperatures up to 225 °C, or with a flat, PTFE gasket for higher temperatures to 350 °C. Both fixed head and moveable head designs are available. The moveable head, Model 4551 and 4552, reactors are designed so that they can be opened or closed conveniently without removing the cylinder and without auxiliary handling equipment. The split-ring cover clamp sections can be moved into place from the sides, and the cap screws can be tightened with the vessel in place in its heater. The fixed head versions, Model 4553 and 4554 (Pictured is the 4554 Reactor, Two Gallon Vessel, Opened to Show the Internal Fittings and Serpentine Cooling Coil), allow the head (and the connections made to it) to remain in place while the cylinder and heater are lowered with the aid of the included pneumatic lift system.

The 1 gallon size is usually recommended for high viscosity polymer studies, with a bottom drain valve added for convenient product recovery. As with the smaller floor stand models, these larger, self- contained systems can be equipped with a variety of attachments, such as: condensers, solids charging port, bottom drain, special motors, special heaters, jacketed vessels and automatic valves and regulators. Because of the higher wattage heaters for these reactors, all models in the 4550 Series require a 230 volt power supply.

Series 4550 Reactor 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 2 gallon, T316SS, removable head reactor with an O-ring seal, heavy duty magnetic drive stirrer, 230V Variable Speed 1/2 hp motor, 2000 psi gage, serpentine internal cooling coil, bottom drain valve, and programmable controller with pressure display module and a high temperature cutoff module would be listed as:
