Insulated Shipping Boxes at Air Sea Containers
At Air Sea Containers, we specialise in high-performance insulated shipping boxes tailored to the strict demands of the cold chain.
Whether you’re planning on transporting temperature-sensitive pharmaceuticals, laboratory samples, or perishable food items, our comprehensive range includes both thermal control packaging (which is dry ice compatible) and ISO shippers (gel or cool pack solutions).
Each solution is rigorously tested to provide reliable protection across a range of temperature requirements, from -20°C frozen to 2° to 8°C chilled conditions.
Thermal Control Packaging
Designed for a qualified temperature range of below -20°C cold chain needs, our thermal control boxes provide effective insulation when used with dry ice.
These durable solutions are able to maintain an ultra-low internal temperature of -20°C during transit, making them ideal for frozen foods or biological materials and pharmaceutical products when used with appropriate infectious substance packaging.
Each box is also constructed with durable outer packaging and features a high-efficiency ventilated insulation system to prolong cold life. The systems are pre-qualified for sub-zero performance, typically holding frozen conditions for up to 2.5 days or longer, depending on external temperatures and loading configuration.
This range is particularly suited to:
- Shipments requiring frozen conditions throughout multi-leg journeys.
- Export routes or supply chains without access to active refrigeration.
- Laboratories requiring reliable -20°C transport without compromise.
Available in multiple sizes and configurations, these boxes offer an easy, compliant way to meet shipping requirements for deep freeze items, including compatibility with regulations when shipping with dry ice.
ISO Shippers
Our ISO shippers are passive insulated containers engineered to maintain chilled temperature ranges (2°C to 8°C) using gel packs. They are a trusted solution for transporting sensitive healthcare products, vaccines, clinical trial samples, when used with appropriate infectious substance packaging, and non dangerous goods such as food items.
These systems qualified with the use of gel packs, making them especially suitable for applications where dry ice may be restricted.
With configurations available that provide up to 72 hours of qualified temperatures, our ISO shippers range offers a dependable thermal control system.
All solutions are pre-qualified for specific thermal performance, ensuring temperature integrity from dispatch to delivery, so be sure to check specific product information.
