Cost-effective alternative to:

A stack of dry ice cubes

Dry Ice requires a shipper to handle using personal protective equipment (PPE), actively manage the inventory/sublimation-loss, and print and apply costly hazardous materials labels. They can also potentially face fines.

A cold gel pack

Gel packs offer cheap refrigerants but cost significant payload capacity. They also have the potential to leak.

A rigid plastic bottle

Rigid plastic bottles are costly and have an initial high carbon footprint that reduces coolant capacity. They promise reusability but often don’t offer a return program.

ThermaBrick® Refrigerant Bricks Properties

Dimensional Stability: Minimal Expansion When Frozen

ThermaBrick® Refrigerant Bricks are designed to maintain shape during freezing-thawing or transit and are used by companies throughout the world where reliability and efficiency are top priorities. ThermaBrick® Refrigerant Bricks perform up to the cold chain industry standards and commonly exceed customers’ expectations for passive temperature-controlled solutions. At Temprecision International, our focus is on maintaining the consistent quality of our products while delivering innovative cold chain solutions to our customers.

Thermal Stability on the Surface of Passive Refrigeration

ThermaBrick® Refrigerant Bricks excel in maintaining consistent temperatures and outperform traditional gel packs and fluid-filled bottles.

During testing, each ThermaBrick® Refrigerant Bricks undergoes rigorous conditioning at -19˚C for 48 hours to ensure reliability. During our precise testing process, the ThermaBrick® Refrigerant Bricks are vertically aligned in a controlled environment set at 25˚C with 50% humidity. We use advanced infrared imaging to monitor heat transfer, ensuring the highest standards of quality and performance.

The comparison between ThermaBrick® Refrigerant Bricks and Plastic Fluid Bottles over a two-hour time lapse is documented through thermal images, with ThermaBrick® Refrigerant Brick on the left and the plastic bottle on the right.

Results demonstrate the surface temperature of the ThermaBrick® Refrigerant Brick used in the product testing exhibited a more uniform temperature across the surface and held a more consistent temperature longer than the fluid-filled plastic bottle.

Will Not Melt or Lose all of the Fluid if Compromised

With 95% or greater absorption efficiency, ThermaBrick® Refrigerant Bricks will not melt or lose fluid if compromised. Unlike alternative products, if the outside is compromised, the majority of the fluid (PCM) will be retained inside the ThermaBrick® Refrigerant Brick.

ThermaBrick retains fluid when the exterior is damaged or compromised.
Customizable to the Exact Size You Need
A variety of Thermabrick products in various sizes

ThermaBrick® Refrigerant Bricks can be customized to the exact size you need for your specific application without the cost of expensive tooling, allowing your customer to maximize the space available for their temperature-assured cargo.

While internal payload volume increases, exterior volume is held constant. This allows the users a decrease in corrugate or box purchases, and, at the same time, a decrease in logistic costs associated with shipping and maintaining the temperature ranges of that cargo.

High-Efficiency Absorption

Temprecision® Foam has been engineered to meet our customer’s strict absorption requirements and can absorb 95% to 99% of a fluid in a matter of seconds.

Three ThermaBrick packages standing side-by-side

PCM-21, PCM-10, and PCM0 ThermaBrick® Refrigerant Bricks are non-toxic, designed for use in food-grade applications, and are printed with a disclaimer for clear communication to consumers. Toll manufacturing and custom printing are also available.

Maximizing the Internal Volume

Customizing ThermaBrick® refrigerant bricks specific to your application allows you to maximize the internal cargo payload size.

The maximization of the internal cooling capacity and its associated volume with ThermaBrick® Refrigerant Bricks allows for maximum volume achieved for the temperature-assured cargo.

Internal payload volume increases, while exterior volume is held constant. This allows for a decrease in corrugate or box purchases, and, at the same time, a decrease in logistic costs associated with shipping and maintaining the temperature ranges of that cargo.
