Cryopak announces the addition of thermal modeling and simulation services for cold chain packaging.

Cryopak recently announced the addition of thermal modeling and simulation services to its array of cold chain packaging expertise. Cryopak has developed a standard set of processes, options and parameters leading to valid thermal simulation results for existing and new thermal packaging designs.

“The determination of correct simulation parameters and the assessment of appropriate geometric approximations present the biggest challenges in obtaining simulation results that accurately replicate test results,” Landon Halloran, Finite Element Thermal Analyst at Cryopak, said.

thermal modeling and simulation of cold chain packagingThermal Simulation allows Cryopak to accelerate the design process by reducing inventory and chamber time requirements. Multiple variations on a common development idea can be tested to determine the optimal design. The temperature response at any point in the pack-out can be investigated and a wide variety of graphic rendering can be provided to customers.

Cryopak’s cold chain packaging group offers the following thermal modeling and simulation services;

• Creation of Thermal Packaging System CAD Model
• Thermal Simulation of Modeled Temperature-Controlled Packaging System
• Thermal Simulation with Custom Profile.
• Modification of Payload.

“Thermal Simulation is also offered as an integrated part of the full design, qualification and production service from Cryopak,” Halloran said.

“We saw that there was a need in the industry for these services,” Bill Hingle, Marketing Director at TCP Reliable said. “Others in our industry were starting to use the software on a more regular basis and we wanted to keep Cryopak ahead of the curve.”

Cryopak Releases the Tempak Plus Insulated Shipping Container for 2-8°C Shipments

Cryopak recently announced the launch of one of our new products, the Tempak Plus Insulated Shipping Container.

These cost effective insulated shippers with refrigerants are designed for refrigerated 2-8°C (with excursions of 1-10°C) for 24 hour applications.

 

The new Tempak Plus Insulated Shipper has been pre-tested against the standard ISTA 7D summer profile.  Test data for this product is available up on request on Cryopak’s website.

Each Tempak Plus comes complete with the EPS insulated shipping container and the specified refrigerant gel packs. These units are available in either assembled or unassembled based on your requirements. Units also come complete with conditioning and packout instructions.

“This light weight shipping system has minimal components and is ideal for customers looking for an affordable alternative to our stringent 2-8°C pre-qualified product line.”  Eva Langen, Engineering Project Manager, said.

For companies looking for a more affordable insulated shipping system that requires basic qualification, the Tempak Plus product is designed for them.

Design Considerations for a Phase Change Material (PCM) Based Thermal Package

This is an excerpt from a presentation given by Cryopak’s Technical Services Manager, Anthony Alleva on Thermal Management Panel: Phase Change Materials for Thermal Management.

There are many design factors to consider when combining components such as insulated containers, gel packs or phase change materials to be incorporated in thermal package designs used for shipping temperature sensitive products.

The primary drivers for a temperature control package design are:

  • Payload volume and temperature requirements
  • Expected ambient temperatures during transit
  • Duration of the shipment

Basic design steps:

  • Determine the balance of insulation quality and PCM amount so as to overcome the amount of heat flow into or out of the package.
  • The goal is for the PCM to not complete its phase change until the shipment is delivered and unpacked.

EXPERIMENTAL EXAMPLES

PCM Temperature vs Shipment Duration

  • Water Gel: Phase Change at 0°C
  • Phase 5: Phase Change at 5°C
  • Phase 22: Phase Change at 22°C
  • Cube of PCM encased in Cube of Polystyrene
  • Freeze/Thaw all three samples and monitor the temperatures of each

Insulation Quality vs Shipment Duration

  • Water Gel: Phase Change at 0°C
  • Empty Corrugated RSC Box
  • Expanded Polystyrene Lined RSC
  • Vacuum Insulated Panel Lined RSC
  • Freeze all three samples and monitor the temperatures of each
