Bulk Vaporizer

Ambient air vaporizers—either the conventional finned or Ice-RackTM design— are used in conjunction with cryogenic storage tanks to convert liquid to gas, as required by the process. These units vaporize liquid efficiently and economically using natural convective heat from surrounding air, rather than a supplementary heat source or power supply such as steam or electricity.

Designed with no moving parts, the units are largely maintenance free. In addition, their modular lightweight designs allow for easy installation. Units may be arranged in multiple banks, in parallel, or in series patterns.

Benefits

No moving parts make these units essentially maintenance free.
No supplementary heat source or power supply means economical operation.
Versatile, modular design means units can be arranged in multiple banks, in parallel, or in series patterns.

Conventional Finned Vaporizer

The fin configuration increases surface area, allowing for maximum vaporizer capacity in a minimal amount of space.

Features

Standard

All-aluminum, welded and finned construction.
Maximum allowable working pressure of 450 psig.
Low pressure drop

Optional

Stainless steel lining for service up to 6000 psig
Automatic switching valve to allow for defrosting of parallel units

Capacities, dimensions & weights

Nominal Standard Capacities (scfh)*	Approximate Dimensions (ft)	Approximate Weights (lb)
5 000	2.5 x 3 x 10.5	400
23 000	6 x 6 x 16	1 600
33 000	6 x 6 x 22	3 300
50 000	8 x 8 x 22	3 600
*Rated for 8 hours of continuous service at 70 oF and 70% relative humidity. Performance varies with ambient temperature, humidity, flow, duty cycles, winds, solar radiation, freeze period, altitude, defrosting intervals, operating pressure and proximity to adjacent structures. A minimum of 2-3 ft clearance around each vaporizer is recommended.

Ice-Rack or Bare Pipe Vaporizer

Ice-Rack or bare pipe vaporizers are used in high -or continuous- flow applications in front of conventional finned vaporizers to protect them from ice buidup and allow maximum gas through-put before defrost.

Features

Standard

Aluminum pipe construction.
Surface geometry of open no-fin design facilitates natural frost shedding and accelerates the defrost rate.
Maximum allowable working pressure of 400 psig.
Low pressure drop.

Capacities, Dimensions & Weights

-	Approximate Dimensions (ft)	Approximate Weights (ft)
Single-module unit	1,25 x 1,5 x 14,5	65
Four-module unit	3 x 3,25 x 14,5	250
Nine-module unit	5,25 x 5,5 x 14,5	600

Each module is rated for 400 scfh as a vaporizer or 2500 scfh as a boiler/preheater for 2-4 weeks of continuous vaporization.
