Advantages of VAL6 SUN LIGHT WARMTH VAL6's radiant heat penetrates evenly on surface and inside like the sun light. BEST CHOICE FOR OUTDOORS VAL6's performance is unique in the outdoors and unlike forced air heaters, which lose heat from wind and cold air. HEAT TRANSFER The infrared rays transfer straight and directly to the object. NO AIR, DUST FREE VAL6 only sends the heat forward. Dust free and clean. ODORLESS With the automatic air release valve, VAL6 doesn't produce odor nor smoke when switching on and off, and radiates only the heat forward. The exhaust gas goes upward. ENERGY SAVING The fuel is mist sprayed and burned 100%. PORTABLE VAL6 is portable with wheels (excepting Daystar). SAFETY Equipped with standard safety devices including flame monitor, also with safety guard. EASY AND SPEEDY VAL6 can start up or shut off in seconds and reaches the peak of efficiency in couple of minutes. These operating characteristics provide complete flexibility and are keys to energy efficiency and conservation in application not needing continuous heat application. Straight heating and drying Radiant heat travels in straight lines and, unlike hot air, does not go up to the ceiling, nor can be blown off with the wind.  Thus, only the aimed surface and object is warmed and/or dried economically without raising the surrounding space temperature.
