Electrothermal

Our RAK water and ration heaters provide potable hot water and heat meals ready to eat (MREs) on demand to give a hot meal and drink for personnel whether under combat conditions, on patrol or back at base. They are rugged, manufactured to withstand the most harsh environments and can be installed in armoured vehicles, patrol boats and helicopters.

Our current range of RAK water and ration heaters includes:

• RAK 15: operates off 15A and is designed for installation in tanks and trucks
• RAK 30: draws 30A to heat faster and is designed for the marines and special forces
• RAK 110: operates on 110V at 400Hz for use within helicopters, such as air sea rescue

Electrothermal will soon be able to offer a ‘chiller crockpot’ with all the benefits of the RAK15/30 coupled with the additional benefit of cooling.

Robust ration heaters for military vehicles

The RAK15/30 is at the optimal size to fit into the cramped quarters of a tank, or other military vehicles, and can provide hot meals and drinks for its five person crew, heating two pints of water and five MREs simultaneously. When used for water only, the RAK15/30 can heat up to 1gal of potable water for drinks, washing or medical purposes. Depending on the power rating, the RAK unit can heat 1gal of water in just 20 minutes under normal ambient conditions.

The heater does work in extreme climates too but it may take longer to heat the contents if the prevailing temperature is bitterly cold. When switched off, with the cover closed and locked, the thermally insulated unit keeps its contents piping hot for between four and six hours.

Food and water heaters for modern military operations

RAK15/30 units are designed to withstand the rigours of modern conflict and have been comprehensively tested to meet military standard specification MIL-PRF-44466D, MIL-STD-461 and MIL-STD-810. They are also certified for food heating after meeting NSN ANSI 4-2007.

The outside of the RAK15/30 unit remains cool-to-touch to ensure safe transit should the product be mounted on the back door of a vehicle, or be located in an exposed position. The cool-to-touch feature also gives the unit a very low thermal signature, which is critically important for maintaining discretion during military operations.

Constructed from a robust stainless-steel outer casing, the unit is sealed to be water-tight, so that any steam is retained within its interior. It has both low and high temperature settings and its own built-in control, so that a separate control unit is no longer necessary. The choice of heating ranges is either 66ºC – 71ºC (on LO setting), or 82ºC – 88ºC (on HI setting).
