Ambient Air Heated Forced Draft Vaporizers
The performance of ambient forced draft air heated vaporizers, which use the relative Ã¢â¬ÅheatÃ¢â¬Â of the atmosphere to derive the energy necessary for the vaporization of the liquid cryogen, is subject to many factors. These include flow rate, duty cycle, ambient temperature, relative humidity, freeze period, altitude, wind, solar radiation, operating pressure and proximity to adjacent structures. The effects of average solar and wind conditions are not included in quoted ratings. Performance is based on mean ambient conditions of 70 0F (210C) and 70% relative humidity. Special conditions may vary considerably for different application, thereby affecting performance. Ambient forced draft vaporizers represent the most cost effective equipment to vaporize or re-gasify liquid cryogens. Once installed there are minimal maintenance costs. All that is required is regular defrosting of the heat transfer elements.
