Base Calculation: We assume a baseline sublimation rate of 5 lbs per 24 hours for a standard 10lb meat shipment in a 1" thick EPS cooler.
Transit Cycles: Transit days are calculated as full 24-hour cycles. "2 Days" = 48 hours of required cooling duration.
Box Size Factors:
- Small (10lb): 1.0x Multiplier (Base)
- Medium (20lb): 1.5x Multiplier (Increased surface area)
- Large (40lb): 2.2x Multiplier (Significant volume increase)
Insulation Efficiency:
- Standard: 1.0x (1" EPS Styrofoam)
- High Efficiency: 0.8x (1.5"+ EPS or Insulated Liners) - Reduces ice need by 20%.
- Premium: 0.6x (Vacuum Insulated Panels / Green Cell) - Reduces ice need by 40%.
