Industries

Plant we know before we arrive

The systems, the standards and the constraints differ enough between these that a generic control system pitch is worth very little. Each page is written for one of them.

Control systems for semiconductor fabs

Fab utilities — PCW, process vacuum, extraction, scrubbers, DI and cleanroom air — where an unplanned stop is measured in wafers, not minutes.

Systems

  • Process cooling water (PCW) systems
  • Process vacuum systems
  • Central extraction systems
  • Fume scrubber systems
  • Exhaust systems
  • DI water systems
  • +4 more

Control systems for pharmaceutical plants

Utility and process control for regulated manufacturing — cleanroom, HVAC, purified water and extraction — with the documentation trail the regulator expects.

Systems

  • Cleanroom pressure cascade and differential pressure monitoring
  • HVAC and air handling units
  • Purified water, DI and RO systems
  • Chiller plant and process cooling water
  • Central extraction and fume scrubber systems
  • Exhaust systems
  • +2 more

Control systems for food and beverage plants

Process, utility and packaging-line control in wash-down environments, where changeover time and traceability decide the economics.

Systems

  • Process plant control and batch sequencing
  • CIP and sanitation sequences
  • Conveyor systems and packaging line integration
  • Chiller plant, cooling towers and refrigeration
  • HVAC and hygienic area air handling
  • RO and DI water systems
  • +3 more

Control systems for water and wastewater plants

RO, DI, effluent and treatment plant control — usually distributed across a site, often on ageing Citect or Modicon, and always required to keep running.

Systems

  • RO and DI water plant
  • Wastewater and effluent treatment (ETP and STP)
  • Dosing and chemical distribution systems
  • Pump stations and transfer control
  • Filtration and backwash sequences
  • Blower and aeration control
  • +3 more

Building automation and facility control

HVAC, chiller and utility control for industrial and commercial facilities, with energy monitoring that produces numbers somebody uses.

Systems

  • Chiller plant and sequencing
  • Cooling towers
  • Air handling units and ventilation
  • Cleanroom and controlled-environment air
  • Compressed air and process vacuum
  • Central extraction and exhaust
  • +3 more

Control systems for petrochemical and chemical plants

Utility, transfer and gas system control in hazardous-area plant, where the interlock design is the deliverable and the graphics are a detail.

Systems

  • Gas and chemical distribution systems
  • Tank farm and transfer control
  • Fume scrubber systems
  • Central extraction and exhaust
  • Process cooling water and chiller plant
  • Effluent and wastewater treatment
  • +2 more

Control systems for nutrition and ingredient plants

Powder handling, blending and drying control where recipe accuracy and batch records carry the same weight as throughput.

Systems

  • Powder handling and pneumatic conveying
  • Blending, dosing and weighing systems
  • Spray drying and evaporation plant
  • Batch and recipe control
  • CIP and sanitation sequences
  • HVAC and hygienic area air handling
  • +3 more
