Background
The need to heat or cool the body has always existed, both through medical and comfort aspects. Disposable products such as ice blocks have been used for cooling, which is not comfortable or healthy at all to apply directly on the body. Imagine a liquid that has the freezing point of +24 C instead of the standard of 0 C for water. The liquid melts when it exceeds the temperature of +24 C and freezes when it drops below (This means that the liquid is frozen at regular room temperature).
When a liquid transfers from liquid to solid form, it's called phase change, see the diagram to the right. Solvini offers a wide selection of pads with different freeze - and melting points to please specific demands of temperature.
The human temperature at the skin is normally around +32 C. For example, if a cooling pad with +24 C is placed on an elbow, it will keep cooling it down until the accumulated energy in the pad is consumed. This takes about 2 hours, depending on outside temperature. The pad can thereafter simply be removed and be recharged in regular room temperature (below +24 C). This procedure can be repeated up to 3000 times without any connection of outside energy source such as electricity. Our products help you to save time and be environmental friendly!
Today, we currently offer pads with the following cooling/melting temperatures:
+ 7 C for a horse or human with injury
+24 C cooling for human or animal
+32 C heating for human or animal
The heating pads function with the very same principle: A +32 C could for example be heated to +40 C and will last (return to freezing point) for about 2 hours after being applied. Notice that the heating pads can only gain energy at a temperature above its freezing point and regular room temperature are therefore not sufficient. Putting the pads in hot water, desiccator or a radiator allows them to reach the desired temperature before they can be used.
