Typical Mortuary Cooler Temperature Ranges

Use Common range Notes
Short-term holding (refrigeration) About 36–40°F (2–4°C) Used for holding ahead of services, viewing, or transfer.
Longer-term storage (freezing) At or below about 0°F (−18°C) Used when the deceased will be held for an extended period.
Always confirm your own requirements. The right setting depends on how long the deceased will be held, your facility’s policies, and the rules in your state or jurisdiction. Treat the ranges above as general guidance, not a regulation, and verify what applies to you.

Why Staying In Range Matters

  • Holding conditions affect preservation and the families you serve.
  • Inspectors and policies often expect records that show the cooler stayed in range.
  • A drift overnight is easy to miss without monitoring and alerts.

HALO does not set or change your cooler temperature — it helps you stay aware of whatever range you choose, alerting you on excursions and keeping an audit-ready record. See temperature alarm, compliance logging, and the HALO overview.

Frequently Asked Questions

What temperature is used for short-term holding?

Many facilities hold at roughly 36 to 40 degrees Fahrenheit (about 2 to 4 Celsius). Confirm your own policy and local requirements.

What about longer-term storage?

Longer-term storage commonly uses freezing temperatures, often at or below about 0 degrees Fahrenheit (about minus 18 Celsius).

Does HALO set the cooler temperature?

No. HALO is monitoring only — it tracks, alerts, and logs. Setting the temperature stays with your refrigeration system.
