Experienced Manufacturing Engineers

Trial & Production Facilities


Dube Engineering’s manufacturing engineers maintain process skills needed to compete in the chemical industry. Using classical engineering skill sets or Lean / SixSigma, we offer talents that can improve your efficiency and throughput. Call on one of our certified engineering consultants at our Lancaster, PA industrial design manufacturing company to learn more about what we can do for you.

Our extensive background includes continuous processing and batch processing with a variety of chemicals at various conditions. If you are using an obscure chemical or having problems finding companies with experience in that chemical, look for similar chemicals within the same family or characteristics for help.

Our Most Familiar Reactions

The items below are a partial list of reactions and equipment Dube Engineering has experience with:

  • Reactors (Chemical reactions, exothermic, endothermic, condensing, hydrogenation, etc.)
  • Mixers
  • Blending
  • Mechanical material transfer (screws, belts, bucket conveyors)
  • Pneumatic material transfer (dense and dilute phase)
  • Grinding (cryogenic and ambient)
  • Extrusion (compounding, single and twin screw)
  • Pumps (positive displacement, centrifugal, piston, gear, lobe, etc)
  • Heat exchangers (TEMA, shell and tube, plate and frame)
  • Dryers (Fluid bed dryer, spray dryer, calciner, rotary drums)
  • Bagging equipment (small 30lb bags through 2000lb super sacks)
  • Crystallizers
  • Screeners
  • Ion Exchanges

The certified manufacturing engineers at Dube Engineering have hands on experience with many chemicals.


Enigineers with Expertise in Uncommon Elements

Below is a list of the abnormal chemicals our team has worked with:

  • Pyrophoric – sodium, lithium, nickel, boron, silane
  • Flammable – hydrogen, vinyl chloride monomer (VCM), dimethyl ether
  • Acids – sulfuric, nitric, hydrochloric, adipic
  • Bases- ammonia, sodium hydroxide
  • Plastics- Polyvinyl chloride, nylons
  • Sugars – corn syrup, mannitol, sorbitol, maltose


If you’re having a hard time finding resources (materials, equipment, personnel, etc.) within your area, look across resources for similarities. If you’re running an exothermic reaction at high temperatures, look at metal smelting for equipment and materials that can take the temperatures. There’s probably someone in a different field doing what you want, you just need to find it and apply it to your circumstance. Let Dube Engineering point you in the right direction.
