El operating temperature range of a dry ice pack defines how effectively you can keep your products frozen or ultra-cold. Dry ice sits at −78.5 °C (−109.3 °F), and its performance depends on insulation, flujo de aire, and pack-out design. This guide explains how cold it gets, cuanto dura, and how to use it safely for shipping in 2025.

What is the operating temperature range of a dry ice pack?
En términos simples: the operating temperature range of a dry ice pack extends from around −90 °C to −60 °C in ultra-cold setups and up to −20 °C for frozen shipments. The coldest point, −78,5°C, is the sublimation temperature of carbon dioxide—the point where it turns directly from solid to gas.
Dry ice sublimates instead of melting, so it produces no liquid water and keeps products dry. That makes it perfect for temperature-sensitive items like vaccines, comida congelada, y muestras biológicas. The consistent, ultra-low temperature ensures a stable cold chain with minimal contamination risk.
Why −78.5 °C is ideal for logistics
Dry ice offers roughly twice the cooling capacity of water ice and lasts up to four times longer when properly insulated. This efficiency provides reliable performance for long-haul shipments or critical pharmaceutical logistics where even minor temperature deviations can affect product quality.
How cold can a dry ice pack get compared with other cooling agents?
| Agente refrigerante | Rango típico | Duración | Key Advantage | Common Use |
|---|---|---|---|---|
| Paquete de hielo seco | −78.5 °C to −60 °C | 24–72 h | Frío extremo, no liquid | Alimentos congelados, biológicos |
| Gel/PCM Pack | −20 °C to +8 °C | 24–96 h | Reutilizable, steady temp | Vacunas, entrega de comida |
| Refrigerant Brick | −10 °C to +4 °C | 48–72 h | Moderate cold | Produce, lácteos |
| Hielo regular | 0 °C to −2 °C | 6–12 H | Inexpensive | Viajes cortos |
Key takeaway: Only dry ice reaches true ultra-cold ranges, but proper insulation and safety precautions are crucial to maintain performance and protect handlers.
How insulation and container type affect performance
| Tipo de contenedor | Calidad de aislamiento | Tener tiempo | Recommended Ice |
|---|---|---|---|
| Espuma de poliestireno (EPS) | Excelente | 48–72 h | 5 lb / 24 h |
| Plastic Cooler | Bien | 36–48 H | 6–8 lb / 24 h |
| Caja de cartón | Moderado | 24–36 horas | 10–12 lb / 24 h |
| VIP Container | Outstanding | 72 h + | 25 % Hielo menos seco |
Mejor práctica: always size your dry ice load based on insulation quality, duración del envío, y temperatura externa.
Expert tip: Use multiple 24-cell dry-ice sheets between product layers to distribute cooling evenly.
How long does dry ice last—and how much should you use?
Dry ice sublimation depends on insulation and ambient conditions. De término medio, 5–10 lb por 24 horas per standard shipper is typical.
Quick estimation method:
-
Add trip hours + buffer (p.ej., 48 h + 12 h = 60 h)
-
Choose sublimation rate: VIP 0.1–0.2 kg/h, EPS 0.2–0.4 kg/h
-
Multiply: 0.3 kg/h × 60 h = 18 kg baseline
-
Agregar 15 % buffer → ≈ 21 kg dry ice total
Re-validate each lane with temperature loggers and adjust for seasonality.
Safety and handling best practices
Dry ice can cause severe frostbite or pressure buildup if misused. Always follow these safety principles:
-
Use insulated gloves and goggles to prevent skin injury
-
Vent all containers—never seal airtight
-
Store in insulated, non-sealed boxes, not freezers
-
Avoid confined spaces—1 kg of dry ice releases about 541 L of CO₂ gas
-
Label shipments “Hielo seco / Dióxido de carbono, solid” with the net weight
Para transporte aéreo, airlines typically limit dry ice to 2.5 kg por paquete. Freight follows UN 1845 (Clase 9) standards and IATA PI 954 pautas.
Practical temperature-control strategies
-
Layered pack-outs: Place dry ice on top and bottom for even cooling
-
Combine with gel packs: Stabilizes gradients for long trips
-
Monitor with data loggers: Confirm real temperatures, not estimates
-
Plan for duration: Adjust quantity for each lane and stop frequency
-
Avoid overload: Too much dry ice can rupture sealed packages
Ejemplo de caso: A biotech shipper reduced losses by 38 % using a dual-phase setup—dry ice beneath and PCM packs above—to maintain −65 °C for 60 horas.
2025 innovations and sustainability trends
The cold-chain industry is shifting toward smarter, greener solutions:
-
Reusable polymer-based “dry ice” packs that can freeze down to −80 °C
-
Paneles aislados de vacío (personaje) that extend hold time while cutting weight
-
IoT temperature sensors para seguimiento en tiempo real
-
CO₂ capture systems producing lower-carbon dry ice
-
Automated re-icing stations at logistics hubs for multi-day routes
These innovations reduce CO₂ consumption by up to 25 % and improve compliance with new environmental standards.
Preguntas frecuentes
Q1. What is the coldest temperature a dry ice pack can reach?
Up to −78.5 °C (−109.3 °F) at the surface; payloads typically stay between −90 °C and −60 °C depending on insulation and standoff distance.
Q2. ¿Cuánto dura el hielo seco en un refrigerador??
5–10 lb typically lasts 24–48 hours; VIP containers extend that to 72 horas o más.
Q3. Can dry ice damage food or packaging?
Sí, direct contact may cause freezer burn—always use separators.
Q4. Is dry ice safe for air travel?
Sí, within airline limits (2.5 kg por paquete) and with proper venting and labeling.
Q5. Son reutilizables?
CO₂ dry ice evaporates completely, but the insulated containers and polymer packs are reusable.
