A collection of ThermaBrick Refrigerant Bricks in all shapes and sizes for sustainable food packaging.

Temprecision International is the custom solutions provider of shaped refrigerant bricks to companies seeking superior end-user experiences by working with you to protect and maximize payloads, minimizing risk through technical and regulatory support, and matching your temperature control packaging needs with a customized product delivered on your tight timeline.

ThermaBrick® Refrigerant Bricks are cost-effective, passive refrigerants that are customizable to any size and shape, designed to reliably maintain your cargo’s temperature.

How ThermaBrick® Refrigerant Bricks Protect and Maximize your Payload

  • Offers cost-effective cooling capacity
  • Available in any dimension to eliminate dunnage
  • Maintains stackability
  • Most efficiently optimizes the contents of a container to minimize box weight
  • Printable with your company logo
  • The foam absorbency actively masks most leaks and punctures
  • Easily customizable to optimize packout
  • Safe and effective coolants for temperature-controlled packaging
  • Targets dimensional weight pricing strategies

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, print and apply costly hazardous materials labels and, where they can potentially face fines.

A cold gel pack

Gel packs that offer cheap refrigerants but cost significant payload capacity and leak.

A rigid plastic bottle

Rigid plastic bottles that are costly and require an initial high carbon footprint that reduce coolant capacity and 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 industry standards and commonly exceed customer’s expectations for passive temperature control. At Temprecision International our focus is on maintaining the consistent quality of our products while delivering innovative solutions to our customers.

Thermal Stability on the Surface of Passive Refrigeration

ThermaBrick® Refrigerant Bricks hold temperature more consistently than gel packs or fluid-filled plastic bottles. ThermaBrick® Refrigerant Bricks are designed and proven to have the following properties when subjected to the below-listed conditioning sequence:

Conditioning: ThermaBrick® Refrigerant Bricks are conditioned at -19 ˚C for 48 hours prior to measurement. Thermal chamber was conditioned at 25˚C and 50% humidity. ThermaBrick® Refrigerant Bricks were placed in a vertical position to better observe heat transfer. An IR camera was placed 1 meter away to capture the images.

Equipment: FLIR Camera, TEMPTALE Sensors

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.

  • PCM+18
  • PCM+22

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 of 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 and allowing your customer to maximize the space available for their temperature-assured cargo.

Internal payload volume increases, while 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

Custom size specific to your application allows you to maximize the internal cargo payload size.

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

Internal payload volume increases, while 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.
