Mobile & Purging Ambient Cryogenic Vaporizers from CRYOGAS equipment are manufactured using more than 20 years of robust experience and proven track record for various land based, On-shore & Off-shore applications.

Liquid Nitrogen is popularly used for various simulation, testing, purging, pigging, blanketing and similar such applications at sites. 

CRYOGAS over the last 20 years has supplied more than 1,000 Units for On-shore and Off-shore applications.  These Units are available for low pressure, medium pressure and high pressure applications.  Most popularly Cryogenic Tankers are connected to High flow Vaporizers for extremely high flow purging and blanketing applications.

For Off-shore requirements, ISO containers coupled with Mobile Cryogenic Vaporizers are used for purging and testing applications.  Based on the criticality and corrosiveness of the atmosphere, a frame structured is selected for robust and multiple handling. Many times, SS frames are utilized for longer life.  Such Mobile Purging Skids are also available with High Pressure Pump and control panel for high pressure testing and pigging solutions.

CRYOGAS also offers interconnecting piping precisely designed while taking care of contraction and expansion w.r.t. stress analysis.

Equalised distribution of cryogenic liquid into different vaporizer units in a bank is extremely important to avoid preferential flow of cryogenic liquid and eliminating the possibility of preferential short pass.  This also helps utilize full capacity of Ambient Cryogenic vaporizers and ensures modular vaporization at all times.

Accurate design of headers manifolding within the vaporizer enable complete utilization of entire vaporization circuit & avoids preferential flow, control the pressure drop and optimize fin configuration.

Preferential placement of fins i.e. 4, 8 and 12 in different vaporization zones ensure maximization of vaporizer capacity, at the same time use aluminium mass at the right place, reduce defrost cycle time and enhance super heating.
