BARRELS insulated thermal cover for liquids and paints
The insulated thermal covers for barrels are used as a passive cooling system to maintain and preserve the temperature of temperature controlled (time-temperature sensitive) products such as fluids, water, water based paint products, etc… which are loaded into a barrel. Mostly the thermal covers for barrels are used for frost protection to make sure that the fluids do not freeze during a certain transport or storage time.
The insulated thermal cover for barrels is flexible and has only one closure at the front in the middle which makes the cover easy to use and to close. This model is easily pulled over the goods and closed with the velcro closure system. Please notice that this cover needs to be reaching the ground floor to prevent an airflow (open thermal bridge) at the bottom of the goods. When more barrels are loaded on a pallet the choice can be made to insulate all the barrels at once with a special thermal insulated cover for pallets.
Single use or multiple use insulated thermal covers for barrels
Tailor made covers: The insulated thermal cover for barrels can be tailor made for single use or multiple use purposes. Single use thermal covers or thermal blankets are mostly used for transport systems where a return logistic is hard to organize. The thermal covers can be equipped with tracking and tracing systems so the flow of the thermal cover can be traced and followed in the total cold chain of the time-temperature sensitive product.
Insulation material on rolls: Next to thermal covers, the barrels can also be insulated with insulation material on rolls which is cut to the required size to wrap the barrel. This is also a single use application and avoids a tailor made production
Technical specifications of the thermal covers for barrels
The thermal cover or insulated cover for barrels is produced tailor made according to the wishes of the customer. The thermal covers can be produced – manufactured according to required dimensions, colors, models, required insulation quality etc. If you have special requests, just let us know.
Preservation and stabilization of the product temperature
The insulated thermal covers for barrels are used to preserve or stabilize the temperature of the products, which are protected by the thermal cover, as long as possible. The time that the temperature can be preserved of stabilized, or the speed of temperature increase or decrease, is depending on the insulation quality. Thermal covers or insulated covers with middle closures are manufactured with a certain Temax insulation material which have a certain insulation quality (R-value or U(k)-value). The higher or thicker the insulation quality, the longer the time of temperature preservation or the slower the speed of temperature change of the products inside the thermal cover.
External convection flows due to open thermal bridges – cold bridges
Next to the insulation quality of the thermal cover with middle closure, the stability or deviation speed of the temperature of the product is also depending on the presents of open thermal bridges or open cold bridges on the thermal cover and packaging set-up. Open thermal bridges are locations in the design or set-up of the thermal cover where an external convection flow (air flow) can exist which has a very big impact on the speed of temperature change. It is therefore very important that open thermal bridges are avoided at all times.
Adding extra thermal energy generators - Gel Packs – Dry Ice – PCM’s Phase Change Materials
When conditioned or time-temperature sensitive products are protected from external temperature influences with a passive cooling systems such as thermal covers with middle closure, the goal is to purely use the available thermal energy of the products to maintain and stabilize the temperature of the products as long as possible. As we know, the result of this stabilization is depending on the insulation quality of the thermal cover combined with possible convection flows and the thermal energy of the products combined with the temperature difference (inside-outside). If the temperature cannot be maintained according to the preferred time-frame, the time can be extended by increasing the available thermal energy. This extra energy can be generated by all kind of passive cooling systems such as gel packs – ice packs – dry ice – PCM’s Phase Change Materials.
Insulating the bottom of the pallet
Most pallets have bottoms which are not completely closed so a convection flow (air flow) can appear meaning that the air can flow through these openings. Therefore it is very important to seal or insulate the bottom of the pallet before loading the chilled or frozen products. An insulated bottom will increase the temperature results significant. To insulate the bottom a on-way use insulation or cardboard can be used.
