Parr 4550 Series 2-Gallon Mobile Stand Reactor with Temperature Control

The Parr 4550 Series 2-Gallon Mobile Stand Reactor is a high-capacity, precision-engineered system designed to handle demanding laboratory and pilot plant applications. Built by Parr Instrument Company, a trusted name in pressure reactor technology, this model extends the capabilities of the smaller 4530 series by offering a larger vessel volume, advanced temperature control, and enhanced mobility. The 2-gallon (7.99-liter) stainless steel vessel is securely mounted on a heavy-duty mobile stand, making it an adaptable solution for researchers and engineers who require both performance and convenience in high-pressure, high-temperature chemical processes.

At HiTechTrader, we provide carefully selected laboratory and pilot plant reactors such as the Parr 4550 Series to meet the rigorous needs of modern research and development. Each reactor is chosen for its reliability, safety, and efficiency, giving scientists and engineers cost-effective tools that support innovation, productivity, and successful scale-up from laboratory to production environments.

Materials and Construction

1. Vessel and wetted parts made from Type 316 stainless steel for excellent corrosion resistance and mechanical strength.
2. Mounted on a mobile stand with lockable casters, enabling safe and effortless relocation in laboratory or pilot-scale facilities.
3. Features a split-ring closure system with 10 compression bolts for secure, leak-resistant sealing during high-pressure operations.

Volume and Vessel Dimensions

1. Vessel Volume: 2 gallons (7.99 liters) for moderate-to-large batch processing.
2. Internal Diameter: ~6.0 inches.
3. Internal Depth: ~17.2 inches.
4. Designed for efficient mixing and reaction performance across a wide range of applications.

Pressure and Temperature Ratings

1. Maximum Allowable Working Pressure (MAWP): 1900 psi (131 bar).
2. Operating Temperature Limits (based on gasket material): 
1. 225°C with FKM O-ring
2. 300°C with FFKM O-ring
3. 350°C with PTFE flat gasket
3. Capable of supporting catalytic reactions, polymerizations, and other high-demand processes.

Mobile Stand & Ergonomic Design

1. Stable frame with compact footprint (20" W × 31" D; ~75" H).
2. Locking casters provide stability during operation.
3. Vessel head can be opened/closed without removing the cylinder from the heater, saving time during sample loading, cleaning, and maintenance.

Stirring & Agitation

1. Magnetic drive stirrer motor: ½ horsepower, variable speed (0–1500 rpm).
2. Impellers: Two 6-blade agitators (3.85 diameter).
3. Magnetic drive eliminates shaft seals, reducing potential leak points and increasing long-term reliability.

Instrumentation & Controls

1. Pressure Gauge: 4.5-inch dial, rated for reactor range.
2. Temperature Monitoring: Thermowells with thermocouples/RTDs for accuracy.
3. Heating System: 2700-watt Calrod band heaters.
4. Integrated Parr PID controllers for precise ramp/soak programming and controlled cooling.
5. Optional add-ons: serpentine cooling coils, drain valves, and pneumatic lift systems.

Safety Features

1. Pressure relief valves and rupture discs protect against overpressure.
2. Electrical interlocks prevent overheating.
3. Robust split-ring closure ensures reliable mechanical sealing under extreme operating conditions.

Applications

The Parr 4550 Reactor is engineered for versatility in advanced chemical processes, including:

1. Pilot plant chemical synthesis and scale-up studies.
2. High-pressure catalytic hydrogenation or oxidation.
3. Polymer research involving viscous reaction media.
4. Pharmaceutical intermediate development requiring precise process control.
5. Bridging laboratory research with industrial-scale production.
