In this, ambient air is used which is free of cost and thus considerable energy saving is achieved. It is more energy saver as compared to electric vaporizers. Atmospheric vaporizers are supplied in one unit , therefore can be installed easily. It consists of a special heat exchanger which is made from copper tubes and aluminum blades.
Air cryogenic vaporizers
These vaporizers consist of two or more finned aluminum elements, manifold together around seamlessly. Each element features eight fins that provide high capacity performance and faster defrosting. It requires no additional facility. There are no moving parts and no additional power or utilities required.
Standard element heights have approximately five sq. ft. of external heat exchanger surface per ft. of length obtaining maximum surface per liner foot. They are
- Maintenance free
- Highly efficient for vaporizing gases or liquids
It is a twin tube heat exchanger. In the center tube liquid CO2 is there and in shell, steam is there. Whenever steam is there at the edge, e.g in breweries , bottles steam evaporator is a very cost effective system of evaporation of liquid CO2. Steam heated vaporizers eliminates the use of expansive electrical energy, which is required on other evaporators.
Principle behind these are : Sensible heat of steam is used to vaporise liquid CO2 . Then condensate is automatically removed. The capacity is designed to most sufficient heat transfer. To ensure trouble free working of the equipment, we provide shut off valves, safety valves reduction valves and filters with our steam heated vaporizers.
In these electrical vaporizers air from atmosphere is blown into set of finned tubes through which liquid CO2 is circulated for evaporation. Two sets are used - one is used when it gets forested due to low temperature of liquid CO2 starts evaporating. The previously used tube gets ready once again. By this process, change over takes place at regular interval. This process continues to give continuous stream of evaporated CO2 gas.
