Air heating equipment is the most effective solution for heating of cargo spaces during transport of goods sensitive to low temperatures and interiors of passenger cabins under cold climate conditions. Particularly is proved successful in city transport with frequent stops (also loading and unloading, etc.) because in the interior as well as in cargo space of the vehicle constant temperature can be kept. All independent heating devices “Planar” can also be installed on boats. These can use fuel directly from the boat fuel tank or from a separate tank installed on a sailboat. Three models of heating devices with different maximum power are available; each of them has a wide range of power and its continuous regulation; this allows choosing the model that is most suitable for the particular transport vehicle.
