Sterilization & Sterile Barrier Manufacturing worked example

Bioburden Test Load with bioburden incubator connected load of 30 kW: a worked example

Push bioburden incubator connected load up to 30 kW and the picture changes. This example computes every intermediate figure at that operating point. Use it when bioburden test load in sterilization and sterile barrier manufacturing is up for an upgrade and you want a defensible savings story.

The inputs for this scenario

  • Bioburden incubator connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Incubation and test cycle runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Units processed during the cycle: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total bioburden test load energy cost = bioburden test load connected load × bioburden test load runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for bioburden test load energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total bioburden test load energy cost.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per kwh.
  • At this operating point the engine returns 3.6 $ / hr for hourly bioburden test load energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where bioburden incubator connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • It multiplies connected load by runtime to get energy used, applies your electricity rate to get total and hourly cost, and divides total cost by units processed for a per-unit figure. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Bioburden test load energy used: 240 kWh (headline result)
