What Is a Deep Freeze Truck Body?

A deep freeze truck body is a specialized refrigerated box engineered to maintain ultra-low temperatures below -40°C (down to -80°C). Unlike standard frozen truck bodies (-25°C ~ -18°C), deep freeze bodies are designed for the most demanding cold chain applications.

Typical temperature ranges for deep freeze truck bodies:

Temperature	Application
-40°C (-40°F)	Frozen biologics, some vaccines
-50°C (-58°F)	Specialized pharmaceuticals, research samples
-60°C (-76°F)	Clinical trial materials
-70°C (-94°F)	Ultra-low temperature vaccines (some COVID-19 vaccines)
-80°C (-112°F)	Biospecimens, cell cultures, cryogenic research

Standard: High-strength front wall panel with FRP inner liner + aluminum outer skin, filled with high-density polyurethane foam. Protective barrier between cab and cargo body.
