4550 Floor Stand Reactors PREFACE Scope These instructions describe the installation, operation and maintenance of Parr Series 4550 Floor Stand Reactors offered in two sizes, 1 and 2 Gallon (3.75 and 7.5 liter). They cover the basic steps to be followed when installing these reactors and describe the function of all standard components. They are intended to be used in conjunction with several related instruction sheets listed on the previous page.

If present on the product, the user must consult the appropriate part of the accompanying product literature for more information. This CAUTION symbol indicates that the surface may be hot. Protective Earth (PE) terminal.
4550 Floor Stand Reactors User’s Responsibility All Parr Reactors and pressure vessels are designed and manufactured with great care to assure safe operation when used within their prescribed temperature and pressure limits. But . . . the basic responsibility for safety when using this equipment rests entirely with the user; who must: 1. Select a reactor or pressure vessel which has the capability, pressure rating, corrosion resistance and design features that are suitable for its intended use.
4550 Floor Stand Reactors Fixed Head or Removable Head Design Parr Series 4550 Series Reactors are furnished with two structural options in addition to the size, pressure range, stirrer motor, controller and similar options. These are: Fixed Head or Removable Head Vessel Design Flat PTFE Gasket or Self Sealing O-ring Closure In the fixed head design, the head of the vessel may remain fixed in the reactor support stand.
4550 Floor Stand Reactors INSTALLATION Pressure and Temperature Limits The working pressure and temperature at which any reactor or pressure vessel can be used will depend upon the design of the vessel and the materials used in its construction. Since all materials lose strength at elevated temperatures, any pressure rating must be stated in terms of the temperature at which it applies. The standard material of construction for Parr Instrument Company is Type 316 Stainless Steel.
4550 Floor Stand Reactors Assemble the Reactor These reactors require at least 10 sq. ft. of workspace in a well-ventilated area with convenient access to an electric outlet, running water, air and a drain. This unit needs to be placed at least 10 inches away from walls or flammable materials. 1. Set the stand in the workspace. 2A. Removable Vessels. First pivot the overarm assembly to the back of the support stand.
4550 Floor Stand Reactors 3. Set the Reactor Controller near the reactor, leaving a space of at least six inches between the controller and the base of the reactor so that the controller will not be unduly affected by radiant heat. Connect the reactor to the controller using information contained in its Instruction Manual 548M or follow the steps below. Labeled connections are provided on the rear panel of the controller.
4550 Floor Stand Reactors IDENTIFY THE VALVES Gas Inlet Valve The gas inlet valve is easily identified when the bomb is open by noting that it is connected to a dip tube that extends to a point near the bottom of the bomb cylinder. This is an angle valve with an attached fitting which provides a socket for attaching the A495HC pressure hose furnished with the reactor. Gas Release Valve The gas release valve is connected to an opening that will not have any fitting installed on the underside of the head.
4550 Floor Stand Reactors OTHER VESSEL HEAD FITTINGS Safety Rupture Disc There is a safety rupture disc attached to the head that is intended to rupture and release the pressure before it reaches a dangerous level. A metal tag wired to the safety head identifies the burst pressure at room temperature for that particular disc. A similar tag is furnished with each replacement disc. This tag must remain with the apparatus at all times so that both present and future operators will be aware of the disc rating.
4550 Floor Stand Reactors ACCESSORIES Internal Cooling Coils Cooling coils can be installed in any of these reactors. Reactors purchased without a coil can have this feature added. Standard cooling coils are made in serpentine configurations. A serpentine coil offers a smaller but effective cooling area and it does not interfere with the use of a liner.
4550 Floor Stand Reactors Pneumatic Lift for Fixed Head Vessels For those models equipped with a pneumatic lift package, the following instructions apply: Technical Support Contact our customer service department with questions concerning the Pneumatic Lift Package. This pressure reactor assembly uses an A2760HC Pneumatic Lift Package to raise and lower the Cylinder. If needed, It can also be used to raise and lower the Heater assembly.

4550 Floor Stand Reactors HOW TO USE THE VESSEL Fixed Head Vessels First, lower the heater and push it aside before attempting to remove the split ring and cylinder. Raise the cylinder support holder to the bottom of the cylinder. Open the gas release valve to discharge any internal pressure. To open the Vessel Remove the split rings. For vessels with a confined, flat PTFE gasket, loosen the six bolts. For vessels with an O-ring closure, loosen the latches on each side of the split rings.
4550 Floor Stand Reactors be replaced with an A490HC hose which has a PTFE lining and a braided stainless steel outer covering. Both of these hoses have the same fittings. The A506HC all metal hose is also available in stainless steel and other corrosion resistant materials. Pressurizing the Vessel Check all valves carefully before admitting gas into the system. The liquid sampling valve must remain closed throughout the charging procedure.
4550 Floor Stand Reactors MAINTENANCE General Maintenance Notes 1. Periodically inspect all electrical wiring and pressure connections for excessive corrosion. Suspect parts should be replaced by components only supplied by Parr Instrument Company. 2. Always use appropriate wrenches on all fittings and valves. Never use pliers or pipe wrenches. 3. Head and cylinder service fixtures are available for convenience and protection of components during maintenance of your reactor. 4.
4550 Floor Stand Reactors Periodic Pressure Tests Each cylinder used in a Parr stirred reactor is tested under hydrostatic pressure to the higher of 1.43 times the rated working pressure at room temperature or 1.30 times the rated working pressure corrected for temperature before it is released from the factory. Micrometer caliper measurements are taken during this test to check the deflection of the walls under pressure.
