We keep you warm.

Do not delete!

Quite simply:

4Fe + 3O2 + 6H2O → 4Fe(OH)3

All substances are carefully mixed in the right proportions to create a granulate that has the ability to react with oxygen.

A soft fleece that allows oxygen to enter, but not the powder to escape, makes the warmer what it is, a small, soft heat pad in various sizes and shapes.

The fineness and type of the iron granulate, the activated carbon, the water buffer and the other components are responsible for the respective quality characteristics of the different warmer types.

The breathable nonwoven fabric surrounding the granules is crucial for both heat generation and heat retention. The precise combination of individual components makes the warmer a portable heating device that provides soothing warmth.

With its large surface area, the carbon in the activated carbon serves as a catalyst and heat accumulator during heat production.

The iron is oxidized during the reaction with oxygen. The heat released underneath is released into the environment via the surrounding fleece.

Both substances are also contained in every warmer. They act as a catalyst and accelerate the reaction.

Thermopad heat pads are designed to generate heat for up to 12 hours after opening the airtight bag, depending on the item.

The reaction is therefore based on the simple principle of chemical oxidation. Thermal energy, i.e. heat, is generated in conjunction with oxygen.

Thermopads have a comparatively high degree of efficiency. Our toe warmers, for example, develop approx. 35kCal. This means that they release over four times more heat energy than electric warmers, for example. One of the reasons for this is that chemical heat accumulators are more efficient than electrical ones.

The temperature and heating time of each Thermopad activated charcoal warmer is controlled by various variables. The air supply, quantity and mixture of components can be varied.
