Ambient Air Vaporizers require no external source of energy and enables vaporization through exchange of heat with the surrounding air. The liquefied gas is vaporized, warmed to almost the surrounding temperature and finally led to the users in its gaseous state.
It offers a full range of Ambient Air Vaporizers in different versions and applications with the following properties:
Fin Tube Vaporizers rely on natural convection while Fan Assisted Vaporizers are equipped with an electric motor operated fan to enhance the air flow and increase efficiency.
Since the surrounding air is at a higher temperature than the product, the heat from surrounding air is transferred to the product in the vaporizer.
While Ambient Air Vaporizers are in use, it is normal to see a mist forming. This is caused by the moisture in the air, condensing and freezing. The intense cold of cryogenic liquid and the moisture in the surrounding air will create frost and ice that will build up on vaporizer tubes, gradually.
Therefore, Ambient Air Vaporizers have a limited running time before the frost and ice has to be cleared from the tubes.
The performance of Ambient Air Vaporizers may be impaired during prolonged periods of severe cold weather. This will create additional frost and ice formation, causing a performance drop.
Heat from the air is transferred through natural convection to the vaporizer pipe. The natural convection is created by the temperature difference between the atmospheric air and the air around the cold pipe.
Heat is conducted from the outside of the pipe to the inner wall. Heat is transferred through forced convection from the inner wall to the product. The forced convection is created by the fluid flow in the pipe.
Fan Assisted Vaporizers are ambient vaporizers that use a fan to increase the efficiency of the vaporizer. Unlike standard ambient vaporizers, the finned tubes are installed within a framework and are enclosed by walls on all sides. The top normally consists of fan housing with side openings to draw in air. The bottom is kept open. An electric fan in the top of the frame provides forced draught downward over the tubes. Forced convection is more efficient than natural convection, therefore fan assisted vaporizers have better efficiency.
