PATTERSON Industries Canada "The Process Equipment People," designs, engineers and manufactures Process Systems to individual customer's process parameters and equipment specifications.

The scope of PATTERSON's activity in these Process Systems can range from the system design and supply of equipment through to the full turnkey involvement including the equipment installation, start-up and full commissioning of the plant.

PATTERSON Process Systems range from modular pilot-size skid mounted research and development units through pre-production to full scale manufacturing sized installations. For a University, a 5 litre PATTERSON Polymer Reactor System was supplied while for major coatings (paint) manufacturer, a 5000 USG PATTERSON Resin System was installed.

PATTERSON Process System projects typically involve the processing of liquids, solids or liquids and solids and generally requiring some of the following functions:

  • Liquids and/or Solids Materials Charging System involving Metering Pumps, Solids Handling Equipment and Weighing Equipment.
  • Premix - Mixing of small quantities of Liquids and/or Solids
  • Reaction Equipment - Process Vessel with Agitator
  • Solvent/Liquid Recovery System of Vapors
  • Vacuum Systems
  • Heating and Cooling Systems
  • Dilution/Blending Equipment
  • Filtration
  • Packaging
  • Instrumentation and Controls

Within the various Process Systems, the scope and type of equipment involved in the individual functions will vary with the requirements of the method of processing necessary to achieve the end product.


PATTERSON Resin Systems have applications in many industries where multiple functions such as mixing and reacting occur. PATTERSON's prime area of activity has been the coating industry for the supply of systems used to produce various types of resins that are used in the manufacture of paints, inks, varnishes, adhesives and other paper coatings.

PATTERSON's knowledge and experience in the design, engineering and manufacturing of Grease Manufacturing Equipment has presented the opportunity to offer both pilot size and full scale production facilities.

PATTERSON also design, engineer and manufacture systems for the Chemical Treatment of various raw materials to change their physical characteristics and recovery of chemicals for industrial processes.

PATTERSON Resin Systems

PATTERSON Industries Canada is recognized as a leading North American manufacturer of custom designed and engineered Resin Systems and Resin Systems Components. PATTERSON supplies equipment for resins, specifically for the coatings industry and typically paints - the types being Alkyd (oil based) and Latex (water based).

Resin Systems generally involve an agitated resin kettle which was in earlier days heated by a direct fired gas furnace and later indirectly heated using steam or thermal fluid to cook the resins; with an electrically driven means of mechanical agitation to mix the resin. Once this resin was cooked, it was then either gravity fed or pumped over to a thinning tank where the pigments, colorants and oils or waters were added to produce the final paint.

Through the avenues of research and development, the range and types of synthetic resins have been greatly increased to include not only alkyd and latex but also others such as acrylic, urethane, epoxy, polyester, phenolic and many others. Production equipment requirements to produce such resins, while meeting plant health and safety standards and also complying with environmental conditions, have resulted in systems now involving sub-systems and components outlined above.

PATTERSON's growth in the Resin Industry runs parallel with the development of Resins for the coatings industry and its expanded range of usage with increasing applications.

From initially supplying the Resin Kettles and Thinning Tank type installations, PATTERSON now design and supply total Resin Systems for major resin producers. Our designs incorporate unique design features and utilize the latest in technological developments that ensure that the systems supplied will meet the production requirements as we approach the 21st century.

Design Features:

PATTERSON Process Systems are designed for maximum equipment efficiency, low operating costs and minimum maintenance that will result in years of dependable service.

Most of the Process System components are designed, engineered and manufactured by PATTERSON.

PATTERSON's years of experience have shown that this approach results in a better coordinated design.

PATTERSON's professional experience together with pride in workmanship ensures the highest standard of equipment for cost effective operation and years of trouble free service.

When you turn your system design over to PATTERSON, you do so with the comforting knowledge that there is one responsibility from start to finish.

Units can be individually designed to customer's material specifications and process parameters upon request.
