$1,399.00

Excursion-Trac™ Temperature Monitoring & Data Logger Kit

A data logging thermometer for logging the most recent temperature observations (525,600…memory can be cleared). This calibrated logger has user-defined time intervals, downloads data to any USB stick, and meets current CDC requirements.

Fridge Temps PCM System for Cool Cube™ 28 (6 Panels)

A set of six panels containing phase change material (PCM) that is nontoxic & biodegradable. These panels for the Cool Cube™ 28 provide advanced thermal protection for refrigerated product due to a 4.5°C/40.1°F melting point (temperature hold).

The Cool Cube™ 28 at Frozen Temperatures (FT-28) is not an ordinary transport cooler (frozen vaccine and FFP carrier). It is an easy-to-carry, qualified container and pack-out system that keeps temperature sensitive product (varicella, MMRV, zoster, Fresh Frozen Plasma) frozen between -50° and -15°C for over 2.5 days – without using ice or electricity! This cooler is ideal for transport, but also excels at protecting valuable product during off-site use and power outages, regardless of hot conditions. The simple, validated, patented technology is the best compact thermal protection product available to maintain the cold chain! NOTE: An ultra-low freezer capable of holding a -25°C/-13°F or lower temperature is needed to prep the panels for maximum hold time.

All Series-20M Prep Methods



Series 20M Prep Method: A – Ultra-Low Freezer Prep


Prep Time: Stage 1-25°C ≈ 24 hours or until PCM is solid




Series 20M - Prep Method A - Ultra-Low Freezer Prep to keep product frozen



1. Store panels in an ultra-low freezer so PCM (phase change material sealed inside the panel) is solid. Shake to verify.


Shake PCM Panel To Check


    • i.e. 24 hrs. @ -25°C turns PCM solid




If the freezer temperature is ever warmer than -25°C, panels may not get completely solid (due to the possibility of supercooling). If panels are stored within the temperature parameters of the product, but are still liquid, panels may be used but the hold time will decrease.




Before assembly, shake panels to estimate the state of the PCM. Solid PCM will keep product frozen in warm conditions the longest. If liquid is heard, panels may be used but hold times will decrease.








Series 20M Prep Method: B – Dry Ice to Freezer Prep


Unless the freezer is always below -23°C, PCM will never turn completely solid. Short-term use is still possible.


Prep Time: Stage 1 Time will depend on amount of dry ice used. Stage 2 ≈ 3 hours




Series 20M - Prep Method B - Dry Ice-Freezer Prep to keep product frozen

1. Place panels with dry ice until PCM (phase change material sealed inside the panel) is solid. Shake to verify.


Time varies dependent on the starting temperature of the panels, size of panels, and amount of dry ice used. CAUTION: Dry ice has a surface temperature of -78.5°C; handle with care.




2. Transfer panels into a fridge for a minimum of 3 hours before use to allow PCM inside to rise to the appropriate operating temperature. Panels may be stored in the fridge until needed for assembly or the PCM melts.


Shake PCM Panel To Check

If a freezer maintains -23°C or below, the PCM within the panels will not melt (melting point is -21.5°C), keeping the PCM solid indefinitely until pack-out. If the freezer maintains -21.5°C or above, periodically check for melting and restart stage 1 to ensure maximum hold times.




Before assembly, shake panels to estimate the state of the PCM. Solid PCM panels will keep product frozen in warm conditions the longest. Liquid PCM panels may be used but hold times will decrease.








Series 20M Prep Method: C – Regular Freezer Prep


Unless the freezer is always below -23°C, PCM will never turn completely solid. Short-term use is still possible.


Prep Time: Stage 1 ≈ 24 hours or until PCM is solid




Series 20M - Prep Method C - Standard Freezer Prep to keep product frozen



1. Store panels in a standard freezer (turned down to its lowest setting) for a minimum of 24 hours before use. Unless the freezer is always below -23°C, PCM will never turn completely solid (short-term use is still possible).


Shake PCM Panel To Check


    • If liquid…panel is at the freezer temp but above -20°C; anticipate shorter hold times.


    • If solid…panel is at the freezer temp but below -23°C; ideal for maximum hold times.


    • If solid/liquid combination…panel is at the freezer temp between -23° and -20°C; monitor longer use periods.




Although panels are liquid, the PCM inside is at the temperature of storage environment after 3 hours (i.e. stored in a -18°C freezer, the PCM panels are at -18°C). Assembling the Cool Cube™ with this additional thermal mass will keep product frozen, just for a shorter amount of time than the lab-validated results.




Before assembly, shake panels to estimate the state of the PCM. Solid PCM panels will keep product frozen in warm conditions the longest. Liquid PCM panels may be used but hold times will decrease.

Thermal Properties of Series 20M PCM Panels

Phase change materials (PCMs) are materials that absorb and release thermal energy during the process of melting and freezing. When a PCM melts, it absorbs the heat from the environment, yet its temperature stays at the melting point until totally liquid. Conversely, when a PCM freezes, it absorbs the cold from the environment, yet stays at its temperature until totally solid. This makes PCM an ideal, passive solution for a variety of applications that require temperature control. The most common PCM is water/ice. Ice is an excellent PCM for maintaining temperatures at 0°C. But water’s freezing point is fixed at 0°C (32°F), which makes it unsuitable for most temperature sensitive applications.




Cool Cube™ PCMs offer custom temperature holds based on their melting point. The PCM inside Series 20M panels has a melting point of -21.5°C/-6.7°F. When panels are solid, contents within the Cool Cube™ stay frozen (at freezer temps around -21.5°C) in hot conditions during an extended period of time. If panels have liquid inside, PCM is at the temperature of the storage environment, but will not prevent warming in hot conditions as effectively as solid panels.

PCM Panel Prep Steps Sequence

  • Always prep the PCM panels before use according to one of the described methods provided by VeriCor.








  • Ensure all components are clean and free of damage.








  • During prep, enable ample air flow around all panel sides (use spacers or racks).







    PCM Panel Spacing Customer Solution








  • Lay panels flat when “freezing”.








  • Freeze/melting times vary depending on number of panels being prepped and equipment specifications being used. Assemble using all six panels for maximum hold time.














  • Using less panels does not change the holding temperature but does decrease hold time.








  • Panels are reusable (10,000+ cycles). (End-of-life disposal: panels use a plastic #2, typically recycled by businesses/communities; PCM is nontoxic and readily biodegradable.)








  • Use a calibrated data logger or other temperature monitoring device to observe internal temperature.








  • Avoid unnecessary opening of the Cool Cube™ after loading payload. Opening of the Cool Cube™ will decrease hold time.








  • An infrared temperature thermometer can assist in ensuring the panels reach a safe pack-out temperature (good for finding out the approximate temperature of each panel).








  • Further the temps are away from the melting point, the quicker PCM will change states.

FT-28 Specific FAQ

Your freezer must be below at least -15°C. -25°C or below is recommended to get the panels solid (for maximum hold time). The colder the storage environment, the less time is needed to condition the panels for use.
To condition the FT-28 for proper use, store PCM panels below -25°C for at least 96 hours.
The FT-28 when properly conditioned will last 94+ hours.
