Refrigerants

Refrigerants are the core active component of any cold chain packaging system — the thermal energy absorbers that maintain your products at the critical temperatures demanded by food safety regulations, pharmaceutical stability requirements, and quality standards across a wide range of perishable goods industries. At Dry Chill, our refrigerant range encompasses a comprehensive suite of solutions engineered for reliability, cost-efficiency, and performance from ambient to sub-zero temperature ranges.

The function of a refrigerant within a cold chain shipment is deceptively simple in principle but highly variable in execution. A refrigerant must absorb heat energy from its immediate environment and maintain a stable temperature differential over a defined transit period, whether that is a two-hour local delivery or a multi-day international airfreight consignment. Selecting the correct refrigerant product is therefore not merely a cost consideration — it is a critical compliance and quality decision.

For the seafood export industry, refrigerants must achieve and sustain temperatures typically between 0°C and 4°C for chilled fish and shellfish. Incorrect refrigerant selection risks both regulatory non-compliance at border inspection points and catastrophic product loss. Australian seafood exporters shipping to Japan, Hong Kong, and Southeast Asia rely on precisely specified refrigerant volumes and types to meet import health certificate temperature requirements.

Meat export operations face similar constraints. Whether shipping grass-fed beef to European markets or lamb to the Middle East, cold chain integrity is non-negotiable. Refrigerants that sustain chilled temperatures through a 36 to 48 hour airfreight journey — including ground handling, transfer, and customs dwell time — are fundamental to export compliance. Always pair your refrigerant with suitable insulated packaging to maximise hold time and minimise waste.

In the meal kit cold chain delivery and grocery delivery sectors, refrigerant performance translates directly to customer experience. A gel ice pack that fails to keep chicken or salmon below 5°C during a summer afternoon delivery creates a food safety incident and a customer retention problem. Pharmaceutical and healthcare cold chains operate under the strictest regulatory frameworks, with GDP guidelines and TGA requirements often specifying PCM gel bricks for precise 2°C–8°C or 15°C–25°C temperature maintenance.

Our range includes dry ice packs (both reusable and disposable), fill-and-freeze ice packs, gel ice packs in standard and bubble-back formats, instant ice packs, PCM gel bricks, and heat packs for controlled temperature maintenance. Each product type suits specific applications and transit profiles — contact our team for refrigerant selection and pack-out calculations.
