Morgue coolers operate between 34°F and 39°F, with most facilities holding 36-39°F for standard decedent storage. Long-term storage uses morgue freezers at sub-zero settings, typically 0°F to -20°F. The refrigerated range slows decomposition enough for services, autopsy, or transport while keeping remains in presentable condition.

Why 34-39°F

Temperatures in this range slow bacterial activity and tissue breakdown without freezing. Freezing damages tissue and complicates embalming, viewing preparation, and autopsy, so facilities hold decedents just above freezing for short- and medium-term storage measured in days to weeks.

Cooler vs Freezer

  • Mortuary cooler (34-39°F): Standard for funeral homes, hospitals, and medical examiner offices; suitable for storage from removal through services, autopsy, or cremation.
  • Morgue freezer (0°F to -20°F): Used for long-term preservation, forensic holds, anatomical donor programs, and mass casualty capacity. See mortuary freezers for long-term storage.

Temperature Monitoring

Units include a digital thermostat with an external display, and audible high-temperature alarms trigger if the cabinet rises above the set point. Many facilities also log temperatures daily or use remote monitoring to document compliance for inspections.

State Requirements Vary

Some states specify maximum storage temperatures or time limits before refrigeration or embalming is required, and requirements differ between funeral establishments and medical facilities. Verify current rules with your state board before finalizing procedures. Additional answers are in the Mortuary Cooler FAQ, or call 1-888-792-9315.
