Hot Meals. No Flame Needed.

Zigrivayka flameless food heaters are designed for situations where conventional food heating is unavailable or impractical. They provide a convenient way to heat ready-to-eat meals in the field, while travelling, during outdoor activities or in emergency situations – without fire, electricity or gas.

The heaters are suitable for military and field use, where an open flame may be undesirable, as well as for hikers, travellers, rescue teams and anyone who needs a hot meal away from conventional heat sources.

Simply add water to activate the heating element. The thermochemical reaction generates heat without electricity or an open flame, allowing a meal to be heated in approximately 15 minutes.

    Flameless Food Heater

    A flameless food heater is a practical, portable solution for heating ready-to-eat meals without fire, gas or electricity. Activated by water, the heating element generates heat through a thermochemical reaction, making it suitable for field use, outdoor activities, travel and emergency situations where conventional food-heating methods may be unavailable.

    How Does a Flameless Food Heater Work?

    A portable food heater uses a thermochemical reaction activated by water. Simply add the required amount of water to the heating pouch, place the heating element inside and add a securely sealed meal. The generated heat warms the food without the need for an open flame or electrical power.

    UTAK flameless food heaters are designed for use with securely sealed, ready-to-eat meals in suitable heat-resistant packaging, including retort pouches and compatible canned foods.
