FIN MODULATION 4, 8 & 12 fins precisely placed in different heating zons for maximised modular vaporization & quicker de-frost cycle.

LNG Cryogenic Vaporizers from CRYOGAS equipment are manufactured using more than 20 years of robust experience and proven track record.

LNG produced at Liquefaction Terminal is transported to end users.  LNG is vaporized / re-gasified for different industrial and commercial applications.  In warmer countries ambient heat is available all 24 hours & 365 days.  This free energy is used for vaporization of LNG and therefore popularly called as Natural Draft LNG Vaporizers.

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

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.

CRYOGAS provides inter-connecting piping between vaporizer banks along with PRS (Pressure Reduction Station) and vaporizer auto switching system.

Generally auto switching is coupled with the PLC system with outlet temperature over-rider. Switch-over is activated at predefined intervals or if the outlet temperature drops below the set point on temperature transmitter. 

CRYOGAS LNG vaporizer operate for 25+ years with ZERO maintenance requirements.
