Heat Cascade Planner

Use exhaust HX (high-temp), jacket HX (mid-temp), and plate HX (low-grade) to reach ~80–85% total utilization. No wasted heat.

Heat Cascade Best Practices

  • • Match high-temperature needs to exhaust heat first (drying, sterilization)
  • • Use jacket water for space heating, greenhouses, and mid-temp processes
  • • Capture low-grade heat for preheating, floor heating, or aquaculture
  • • Consider thermal storage to balance supply/demand timing mismatches
  • • Monitor actual vs design performance—real efficiency often differs
