Electrical Heating Reactor/Chemical Reactor

Core Technology & Working Principle

A reactor and a disperser are usually two machines because they want opposite things. Dispersion needs tip speed and turbulence; a reaction needs a known thermal history and no air. The PDK puts both in one sealed vessel. The toothed Cowles disc throws material radially outward, the flow deflects off the machined wall and returns down the center as a toroidal vortex, so solids are wetted and agglomerates broken at the tooth edge. Heat comes from electric elements submerged in a thermal oil jacket — oil rather than direct electric coils, because oil spreads the heat evenly over the jacket surface instead of putting hot spots against one patch of wall. When the reaction turns exothermic, the pipe coil inside the vessel takes chilled water and pulls the batch back down without waiting for the jacket to cool. Holding vacuum throughout is what stops oxygen darkening a resin or whipping foam into a coating at temperature.

Precision Engineered Details

Four assemblies decide whether a dispersing reactor holds temperature where the operator set it, and whether the heat actually reaches the product instead of the room.

Internal Cooling Pipe Coil

Seen here through the open manway, the coil spirals against the inner wall so an exothermic batch is quenched in the product itself rather than waiting on heat to travel back out through the jacket.

Electric Heating Flange Elements

Elements bolt into flanged bosses around the vessel, each with its own junction box and cable gland, so heater servicing is a flange job rather than an operation on the vessel head.

Load-Cell Weighing Module

The vessel load is carried on calibrated load cells, so each component can be dosed by weight into the batch instead of by volume, and the console keeps the weight record.

PLC Recipe Console

One touch screen runs dosing setpoints, material and liquid temperature, mixing speed and motor current, so a recipe is a stored program rather than a sequence of manual moves.

PDK Technical Parameters

The table below lists the standard PDK line-up. Dispersing power steps up with capacity, and the two largest models cap shaft speed lower because a wide disc reaches the same tip speed at fewer revolutions.

*Parameters represent standard production models. Custom motor voltages (220V/380V/440V, 50Hz/60Hz), variable frequency drives (VFD), multi-tier impellers, load-cell weighing modules and explosion-proof configurations are engineered on request and quoted against the process requirement. Reference projects in your industry are available on request.

Target Application Spectrum

A dispersing reactor is specified where the formulation has to be both heated and sheared in the same vessel, and where air or moisture in the finished product shows up as a defect:

Industrial Coatings

Printing Inks

Polymer Sealants & Adhesives

Waterproof Membranes
