Body Storage Temperature Standards: Cooler vs. Freezer

Mortuary refrigeration falls into two purposes: short-term refrigerated holding and long-term frozen preservation. The right choice depends on how long remains must be stored. The ranges below are commonly referenced industry figures; always confirm requirements with your local and state regulations and your equipment specifications.

Refrigerated holding (coolers)

For short-term storage between services, examination, or release, remains are commonly held at refrigerated temperatures just above freezing — widely cited around 36–39°F (about 2–4°C). This slows decomposition for days to a few weeks while keeping tissue intact for embalming, viewing, or autopsy.

Frozen preservation (freezers)

When remains must be held for extended periods — unclaimed cases, pending investigations, or delayed identification — sub-freezing storage is used. Mortuary freezers commonly operate well below freezing, often cited in the range of about 0°F and lower (roughly -10°C to -20°C) for long-term preservation.

Choosing the right equipment

If your cases are released within days to weeks, a refrigerated cooler is the standard choice. If you regularly hold unclaimed or investigative cases long-term, add freezer capacity such as the 3 Body Oversized Mortuary Freezer. Many facilities run both. For help sizing, see our buying guide.

Frequently asked questions

What temperature should a mortuary cooler be?

Refrigerated holding is commonly cited around 36–39°F (about 2–4°C). Confirm the requirement for your jurisdiction and equipment.

When should remains be frozen instead of refrigerated?

Freezing is used for long-term storage — unclaimed remains, pending investigations, or delayed release — where refrigeration alone would not preserve tissue long enough.

How long can a body be kept in a mortuary cooler?

Refrigerated holding generally preserves remains for days up to a few weeks; longer horizons typically call for freezer storage. Local regulations and case specifics govern actual limits.
