Why Does Temperature Integrity Matter?


Temperature integrity is crucial to your business. Your customers trust you to ship their products safely and economically, and expect that when the goods are delivered, they have retained their quality and value. Certain products are notoriously difficult to ship, like ice cream, frozen prawns, pharmaceuticals, etc. They’re the ones you hold your breath on every time you promise a customer: Yep, we can do that for you. They can thaw fast quickly and once they do, it’s game over for the shipment—and you’re on the hook for the cost. Not just for the product but also for your reputation. Your customer accounts are put at risk when product safety, quality or value retention are compromised.

Traditional Reefers vs. Temperature Integrity

 Some products are so sensitive to temperature excursions that they must be shipped with dry ice or other insulating products to supplement the conventional transport (reefer) units. Inefficient reefers and cumbersome loading and unloading procedures like the ones we write about here put products at risk of temperature excursions.


Conventional reefers set points commonly range from -29°C to +12°C (-20°F to 55°F). In the LTL world, however, with the frequent stops and door openings, and the complicated loading and unloading sequences, reefers often fail to reach and maintain the proper setpoint temperature. We’ve seen evidence of this in our field trials with industry partners.


SnowSHIP™ Makes the Difference

CryoLogistics has introduced a solution to temperature excursions and the claims they generate. We call it SnowSHIP ™. It’s a secure, pallet-sized vacuum insulated shipping unit that delivers precise temperature control.


Not only does SnowSHIP keep your product cold it guarantees its safety and security. With all the touchpoints along the cold chain, your product faces risk like temperature abuse, damage, contamination, theft and even counterfeiting. SnowSHIP takes those risks out of the equation.


SnowSHIP can maintain pinpoint temperature setpoints between -30°C and +8°C (-22°F and 46°F) for days at a time. When we say pinpoint precision, we mean it: SnowSHIP holds temp within +/- 0.5°C regardless of how many truck door openings there are on a trip.


Real-World Data from a SnowSHIP LTL Field Trial

The graph below highlights actual data we gathered from a 2020 field trial of a SnowSHIP unit inside a refrigerated truck. The set point for both the reefer and the SnowSHIP was -1°C (30°F). The route captured in this graph spans 24 hours; the graph highlight below shows a snapshot of one portion of the entire route.

Graph comparing Temperature Integrity in Reefers vs SnowSHIP

You’ll see that the reefer unit (depicted in yellow) took substantial time to pull down and reach the set point, and when it did, it only held the set point for 3 of the total 24 hours. While that doesn’t necessarily mean there was any damage to the product, the measurements we took during this field trial clearly indicate that traditional reefer units aren’t always capable of shipping products that demand a specific and narrow temperature band.


SnowSHIP (depicted in green on the graph) started cold and, with the exception of the time when the product was loaded, stayed cold.


A couple things are important to note here. First, to get the best performance from SnowSHIP, you’ll want to pre-cool it for several hours before you load it. Starting it at the right set point before loading means it takes virtually no energy on SnowSHIP’s part to keep things at that set point. The graph above shows that SnowSHIP was, in fact, properly pre-cooled before use. (You can load SnowSHIP at room temp, but then it’ll expend a lot of its cooling power bringing down the load temperature, and you’ll lose the longevity. Call it “picnic reasoning”: if you put hot fried chicken into your picnic basket, you’ll thaw the ice packs a lot faster than if you cooled the chicken first.)


Second thing to note about the graph: you can see that when SnowSHIP’s door was opened to load product, there was a significant increase in the load space temperature. But once SnowSHIP’s door was closed, the unit went to work fast, pulling down the load space temperature right to the set point—and SnowSHIP did so within a fraction of the time it took the reefer to do the same.


And finally—this is the real juice—SnowSHIP held that temperature precisely throughout the 24-hour duration of the shipment.


Breaks in The Cold Chain Add Up to Big Waste


SnowSHIP changes the cold chain game because it simply doesn’t allow product to fall out of temperature. It’s a small, climate-controlled transport container with precision temperature control, with vacuum insulation to keep all that cold air locked inside.


And that’s a good-news item. Current research indicates that about a third of all food produced for human consumption worldwide spoils in transport. That’s an enormous number! It equates to 1.3 billion tonnes annually, to the tune of $1.9 trillion US dollars. To help you make a meaningful comparison, let’s look at this through the lens of the cost of a tractor-trailer. Say a new rig for your fleet comes in around $150K. Sound about right?


Well, $1.9 T equates to twelve million, seven hundred thousand rigs.


That’s a lot.


And that’s just food waste. When we look at the biopharma industry, we see that a full 20% of temperature-sensitive pharmaceutical products—another $34 billion—is rendered unusable because of temperature abuse.


The crazy thing is, it’s been this way for years, and even though we know it, we’re not changing our behaviour. Perhaps it’s because there’s only been one way to do business in the cold chain. It bugs us all—and it affects us all, especially our bottom line. Didn’t Albert Einstein have some clever quip about trying to solve a problem by using the same old methods? Well, with the introduction of the SnowSHIP system, the status quo has lost its status!


Increase Temperature Integrity and Win the War on Waste


As a new entrant to the cold chain playing field, SnowSHIP is here to give blue totes, dry ice, reefers, blankets, cold walls and gel packs a run for their money. It’s modular, autonomous, affordable, easy to maneuver and use, quick to recharge, and very, very self-aware.


Your high value high-risk products—ice cream, frozen novelties, seafood, bakery—are safe and secure inside a SnowSHIP. You can load the unit, seal it, set it…and forget it.


Unless, of course, you want to track it every five minutes along its entire journey. SnowSHIP does that too, using IoT-enabled track and trace software the reports to your desktop or handheld device..


But seriously. We’ve said this before: SnowSHIP will do its job no matter what’s going on around it. You can stick it in a reefer, stash it in a dry van, or just leave it sitting out on your warehouse floor, and it’s still going to keep the load cold as long as its LC02 supply lasts. And it’ll give you plenty of warning before you need a LCO2 refill.


Add Value For Your Customers—And Hang Onto Them, Too


Adding SnowSHIP to your fleet lets you to bring on new accounts that have strict and demanding temperature requirements. Its reliability and precision deliver a double benefit, helping to strengthen your existing customer relationships and reducing your claims at the same time.


It’s time to do things different.
