Dry Ice for Cold Transportation 

24/7 Emergency Support 

0% Water Contamination Risk 

Reliable Ultra-Cold Shipping Across South Africa 

Dry ice is the ultimate solution for cold transportation, maintaining temperatures of approximately −78.5   °C without leaving liquid residue. Ideal for frozen food, pharmaceuticals, laboratory samples, and industrial products, it keeps goods dry while providing consistent ultra-low temperatures throughout transit. 

Unlike conventional ice, dry ice sublimates directly from solid to gas , preventing moisture damage and ensuring products remain frozen during shipping. Businesses across South Africa—from food distributors and seafood exporters to pharmaceutical companies and research labs—rely on dry ice for secure and reliable cold transportation. 

Breaking the cold chain can spell disaster 

Dry   ice can be used to support and stabilise conventional refrigeration systems during transport, helping maintain consistent temperatures when conditions change. Refrigerated transport helps—but temperature deviations still happen during loading, delays and last-mile delivery. One failure can lead to rejected stock, compliance issues and major losses. 

Dry Ice = Risk Reduction + Compliance Insurance.

Dry Ice vs Other Cold Transportation Methods 

Refrigeration helps control temperature. Dry ice helps guarantee it. 

Other Cold Transportation Methods 

Fluctuate during loading and unloading 

Fail mechanically 

Struggle with last-mile delivery and frequent door openings 

Lose performance during power interruptions or extended stops 

Dry Ice provides: 

Stable cooling (no reliance on power in transit) 

A backup temperature buffer during disruptions 

Support for ultra-low temperature requirements (below -18°C) 

Reduced temperature loss during door openings 

Added confidence for pharmaceutical cold chain compliance

Precise temperature control 

High cost, requires power 

Dry ice is preferred for ultra-cold shipments and situations where passive, reliable cold transportation is essential. 

Why Choose Dry Ice for Cold Transportation 

Ultra-Low Temperature – maintains −78.5   °C for extended periods. 

Dry Cooling – no moisture damage to products. 

Power-Free Operation – ideal for long or remote shipments. 

Flexible Packaging – blocks, pellets, or slices for any container type. 

Dry ice is a proven, reliable solution for food, pharmaceutical, and laboratory cold transportation across South Africa. 

How It Works 

Simple, Reliable Process – Dry ice sublimates directly into gas — no moisture, no contamination, just consistent temperature control from start to finish. 

01 

We Supply 

High-quality dry ice and insulated containers tailored to your exact needs. 

02 

You Ship 

Load your goods with confidence — dry ice provides reliable temperature control in transit. 

03

Use Cases 

When Dry Ice makes the biggest difference 

Emergency backup when refrigeration is compromised 

High-value shipments where failure isn’t an option 

Ultra-cold loads and deep-freeze requirements 

Extended stops & delays (traffic, collections, transfers) 

Door-open heavy routes (multi-drop deliveries) 

Calculating the Right Amount of Dry Ice 

The amount needed depends on transport duration, insulation quality, ambient temperature, and product weight . 

Transport Duration 

Dry Ice Requirement 

12–24 hours 

5–10  kg per 100  kg product 

24–48 hours 

10–30  kg per 100  kg product 

48–72 hours 

30–50  kg per 100  kg product 

Using insulated containers and limiting container openings can significantly extend cooling duration.

How Dry Ice Maintains Ultra-Low Temperatures 

Extreme Cooling Power 

Dry ice’s temperature of −78.5   °C allows it to rapidly freeze products and maintain frozen conditions during long-distance transport. This slows microbial growth, preserves product integrity, and is especially useful where refrigerated vehicles are unavailable. 

Sublimation: Cooling Without Moisture 

The sublimation process—direct transition from solid CO ₂ to gas—keeps products dry while continuously absorbing heat. This makes dry ice the preferred method for sensitive shipments such as pharmaceuticals, frozen foods, and biological samples. 

Optimising Cold Transportation in South Africa 

Dry ice is widely used for cold transportation between cities like Johannesburg, Cape Town, and Durban , and over long rural routes where refrigeration infrastructure may be limited. Typical applications include: 

Food and seafood distribution – preserves quality during long shipments 

Pharmaceutical transport – maintains vaccines, lab samples, and biological materials 

Laboratory and research logistics – keeps samples frozen for testing 

Dry ice is versatile and can be used in pellets, blocks, or slices , allowing businesses to tailor cooling duration and container fit for each shipment. 

No refrigerated vehicle available? Dry Ice is a reliable alternative. 

When refrigerated trucks or cold rooms aren’t available—especially for urgent deliveries, last-mile routes, remote areas, or short-notice collections—Dry Ice provides passive cooling that doesn’t rely on vehicle refrigeration systems. 

Ideal for: 

Standard delivery vehicles (non-refrigerated vans/trucks) 

Courier and last-mile deliveries 

Emergency collections and urgent dispatch 

Rural/remote routes where refrigeration isn’t accessible 

Temporary cooling during vehicle breakdowns or power interruptions 

Why it works: 

Maintains reliable low temperatures in insulated packaging 

Keeps shipments dry (no meltwater) 

Adds temperature stability during stops, delays, and door openings

Best Practices for Safe Cold Transportation 

Use high-quality insulated containers to reduce heat transfer. 

Pre-chill containers before loading products. 

Avoid airtight containers—dry ice releases CO ₂ gas during sublimation. 

Minimise opening during transit to slow sublimation. 

Following these best practices ensures products remain frozen, dry, and safe throughout South Africa’s transportation network.
