Clean utilities are essentially plant support services/systems which have to fulfil regulatory requirements.

In the pharmaceutical, healthcare, food and beverage industries the most common clean utilities are water based. These can be separated into several pharmaceutical grades of purity including Purified water (PW), Highly Purified Water (HPW) and Water for Injection (WFI).

Other clean utilities include clean compressed air, clean gasses (like nitrogen and oxygen), clean steam, special organic solvent systems and vacuum systems.

There are many limitations and disadvantages of conventional utility systems. These include;

  • Mixing of different utilities (cross contamination)
  • Corrosion and Scaling of Equipment Jackets
  • May call for Special Equipment Design (Dual jacket /Limpet)
  • Effective Condensate recovery is difficult
  • Temperature control accuracy is difficult to achieve
  • Thermal shocks to equipment as well as product

Plant engineers are therefore encouraged to understand these limitations and issues so that they apply technically advantageous, best practice solutions and thus realise operational benefits. Such benefits include;

  • Improved product quality
  • Higher product yields
  • Reduced manpower cost
  • Safer operation
  • Simpler operation and maintenance
  • Improved regulatory compliance

Stanseals are a leading authority in the supply of skid mounted, best practice water utility systems, and supply hot water systems and purified plus systems configured to client plant requirements.

Modern plants across all industrial sectors are increasingly moving towards skid mounted, best practice utility systems.  

To meet the different temperature demands of single equipment processes, the following utilities are typically used;

  • Chilled brine -10°C to - 40°C (14 to - 40°F)
  • Chilled water 5°C to 15°C (41to 59°F)
  • Cooling water 25°C to 35°C (77 to 95°F)
  • Hot water 50°C to 95°C (122 to 203°F)
  • Low/High Pressure Steam 110°C to 170°C (198 to 338°F)
  • Thermal Fluid 180°C to 300°C (356 to 572°F)

Stanseals provide skid mounted system solutions for all of the above applications. Our standardised, modular solutions are also commonly customised to suit client specific requirements. Contact Stanseals with your requirement and see that they can do for you.
