Truetech Self-Heating Technology

Since 1990, Luxfer Magtech has been the sole supplier of Flameless Ration Heaters (FRH) to the U.S. Military’s Meals Ready-to-Eat (MRE) program. Since that time, we have supplied over 1.5 billion food heaters to the U.S. armed forces.

Military Flameless Ration Heaters for MRE

As the sole source supplier to the U.S. Military, our FRH manufacturing system is held to the highest quality standards and performance requirements. The patented TRUETECH® Self-Heating Technology is a simple, biodegradable, combination of powdered, food-grade iron and magnesium, salt, and water.

The FRH uses no flame or electricity to generate heat. When water is poured on the heater pad* the Food Heater releases enough heat to warm-up a pre-cooked meal by a minimum of 100 degrees Fahrenheit above the ambient temperature in approximately 10 minutes. Spent heaters are biodegradable and non-toxic. They are easily disposed of as household trash. There are no toxic materials used in the FRH.

Luxfer Magtech has developed sales and marketing agreements for our patented, self-heating technology and meals across the globe. In fact, we have designed commercial FRHs to meet the specific needs of different countries. Currently, we have agreements with companies in Canada, the United Kingdom and Europe, Israel, the Middle East, South Africa, South & Central America, Australia and Japan.
