HydroFreezeโขย and HydroFreezeโข+ are our ice packs containing a unique food safe formula, designed to enable safer shipping ofย frozenย goods. They work in the same way as dry ice, but are much safer as, unlike dry ice,ย HydroFreezeโข products are not classed as hazardous goods when shipping, and they do not require any specialist handling.
Both versions of HydroFreezeโข can maintain temperatures at -20ยฐC for an extended period of time. It consists ofย onlyย food approved, natural ingredients, found in your everyday life!
Regular water/gel ice packs phase change at 0ยฐC (the freezing point of water) so once packed inside your insulated box, they will sit at around 0ยฐC while changing from a solid back to a liquid. These regular water/gel ice packs should only be used for shipping chilled food as they phase change at 0ยฐC โ not cold enough for frozen food, but perfect for refrigerated goods. HydroFreezeโข products have a phase change point of -20ยฐC, which means they hold that temperature while changing from a solid back to a liquid โ and hold the food products inside the insulated box at around the same temperature.
What is the difference between HydroFreezeโข and HydroFreezeโข+?
HydroFreezeโข is a formula designed to phase change at -20ยฐC. When frozen correctly and packed in a good quality insulated box, these ice packs can be used to hold frozen food at a temperature of below -12ยฐC for approx. 24 hours.
HydroFreezeโข+ is our newly developed gel formulation of the previous product and is designed to enable shipping of frozen goods for longer transit times. Like the regular HydroFreezeโข the new HydroFreezeโข+ phase changes at -20ยฐC and can hold food at around that temperature, but where HydroFreezeโข+ really excels is in its longevity. The new HydroFreezeโข+ ice packs will absorb a great deal more energy before they completely freeze, so will need to be in a powerful freezer or will take a longer period of time to freeze. However, once they are frozen and packed inside a suitable insulated container they will hold -20ยฐC for approx. 24 hours or -15ยฐC for approx. 36 hours.
HydroFreezeโข and HydroFreezeโข+ can maintain temperatures at -15ยฐC, however HydroFreezeโข+ can hold that temperature for an extended period of time. Both of these products have been developed with safety, quality, performance and cost in mind, and consist of only food approved ingredients.
HydroFreezeโข and HydroFreezeโข+ are produced in our state-of-the-art manufacturing facility in High Wycombe, Buckinghamshire, with the capacity to cater for all users looking for a safer and more economical solution to sending frozen goods.
Currently using Dry Ice?
Dry ice (solid CO2) is currently the most common consumable used for the shipping of frozen products; it maintains sub-zero temperatures through the process of sublimation - i.e. converting directly from a solid to a gas. Dry ice is classified as a miscellaneous hazard (Class 9) during transportation by DOT and IATA.
Hazards associated with dry ice include risk of explosion and suffocation in an enclosed space, and risk of severe frostbite injury when handled. Dry ice is so cold it will freeze the blood inside your skin if handled with bare hands. For these reasons, many carriers have now restricted or prohibited the distribution of parcels containing dry ice, and the couriers that do still accept it will apply a surcharge to the shipping cost.
HydroFreezeโข and HydroFreezeโข+ eliminate these hazards and offer a safer and competitive alternative โ think of it as a regular ice packโฆ just a cooler version of it!
So What are the Benefits of Using HydroFreezeโข and HydroFreezeโข+
Recommended Pre-conditioning of HydroFreezeโข & HydroFreezeโข+
* Freeze times are largely dependent on the freezer temperature and the quantity that is being frozen at that particular time (i.e. pallet load will take considerably longer to fully prepare compared to a single pack). Ensure sufficient cold air circulation around the product for efficient freezing and be aware they will take longer to freeze than normal water/gel ice packs.
