The Vaporizer Selection Manifold is an automated system for cryogenic liquid oxygen installations that maximizes vaporizer efficiency and reliability. By automatically alternating between two or more ambient air vaporizers, the manifold prevents excessive ice accumulation on any single vaporizer. This process ensures consistent vaporization rates, maintains optimal heat transfer, and reduces the risk of performance degradation or supply interruption due to ice buildup.

Features & Benefits:
- Automatic Switching: Alternates between multiple ambient vaporizers based on a preset timer or system demand, minimizing ice buildup on any single vaporizer
- Peak Efficiency: Maintains vaporizers at optimal performance by allowing one unit to defrost while the other is in use, preventing loss of heat transfer surface area due to ice insulation
- System Protection: Reduces the risk of liquid oxygen entering the gas distribution pipeline
- Customizable Cycle: User Adjustable settings accommodate site conditions and seasonal changes
Control Panel
A NEMA-rated electrical control panel houses the controls for the automatic switching, including:
- Adjustable interval timing relay to set switch cycle duration
- System status indicator lights
Optional low temperature switch to detect downstream gas temperature
Vaporizer Connections
The manifold includes inlet connections to attach liquid oxygen dewars/cylinders, as well as an outlet manifold with filter, regulator, and control valves to supply the vaporized gaseous oxygen. Vent connections allow cylinders to equalize.
Compact and Portable Design
The switching manifold and multiple vaporizers are designed as a relatively compact. By automatically alternating between vaporizers, these systems help maximize vaporization efficiency and output flow rates compared to a single continuously operating vaporizer.
