These new reactors are secured vertically for loading and then safely tilted horizontally for stirring. The reactor can even Stirring biomass such as straw or grasses is not easy to do in a vertical reactor. A line of reactors has been developed by Parr Instrument Company to function horizontally. These new reactors are secured vertically for loading and then safely tilted horizontally for stirring. The reactor can even be designed to tilt upside down for discharge. Horizontal reactors can be designed for capacities ranging from 0.1 liter to 10 liters. The larger systems can be controlled pneumatically to tilt the system upright to open the bottom drain valve. These horizontal rectors can obtain temperatures up to 350 °C and maximum pressures of 1900 psig....

Read More | Parr offers a number of different reactors in the 4570 and 4580 Series in a variety of sizes and with different mountings for operating pressures to 5000 psi (345 bar) and temperatures to 500 °C. All of these reactors have been designed with suitable valves, fittings and modifications to the vessel Parr offers a number of different reactors in the 4570 and 4580 Series in a variety of sizes and with different mountings for operating pressures to 5000 psi (345 bar) and temperatures to 500 °C. All of these reactors have been designed with suitable valves, fittings and modifications to the vessel itself to operate at the higher temperature and pressure ratings. Flat, flexible graphite (FG) gaskets are used for temperatures in the higher range to 500 °C. These can be replaced with PTFE gaskets for procedures in which the temperature will not exceed 350 °C. All cart and floor stand models use ceramic fiber heaters to achieve the higher operating temperatures....

This series expands the available volume of our standard offering by more than five times, while retaining the easy-to-use features our customers have come to expect from Parr. Ideally The 8500 Series of stirred reactors, with volumes of 50 L or 100 L, are the largest reactors offered by Parr. This series expands the available volume of our standard offering by more than five times, while retaining the easy-to-use features our customers have come to expect from Parr. Ideally suited for scale up or pilot work, the geometry, features, and operation are very similar to that of smaller Parr reactors, but with a volume intermediate between lab-scale and traditional production scale stirred reactors.
As shown below, the 4848 Reactor Controller with associated 3 zone slave box allows for electric band heater control, or a jacket can be welded on the cylinder exterior for temperature control via circulator.
The base units are available with a 725 psi (50 bar) pressure rating, though higher pressure ratings are available upon request. As with other Parr vessels, these reactors can be constructed of a variety of commercially available corrosion-resistant alloys.
