HydrOMac ® LH 2 refueling receptacle
Additionally , the nozzle must be constructed so that there is no chance of leakage , and if a leak does occur , the nozzle ’ s operation must be able to be instantly halted to prevent a potentially dangerous situation . On top of that , the nozzle must possess automated flow-control capabilities that enable the operator to be positioned at a safe distance during the refueling process .
One final operational concern with LH 2 is the potential buildup of condensed liquid air on the nozzle during refueling . This condensed liquid air is extremely combustible liquid oxygen . Therefore , the LH 2
-dispensing system must be jacketed and maintain an extremely high vacuum to keep the outer surfaces at ambient temperature , preventing the buildup of liquid air .
The solution
RegO ® Products , a member of OPW Clean Energy Solutions ( OPW CES ), is a longtime developer of systems and equipment for use in the handling of clean-energy alternative fuels , such as LH 2
. Recognizing the challenges that are the hallmark of
LH 2 handling – along with the need to ensure its safe handling in every instance – RegO and OPW CES have developed the HydrOMac ® LH 2 refueling nozzle .
The HydrOMac nozzle offers the following features and benefits :
• Unique design that diminishes complexity in
LH 2 dispensing
• Built-in leak detection capability
• Automated fuel control that enables the operator to remain in a remote location during the refueling process
• Three-stage , thermally isolated method of operation that optimizes efficiency and performance
• Jacketing that meets the low-temperature handling requirements of LH 2 and resists the dangerous buildup of liquid air
• Lighter weight than competitive models , making it easier to handle
These features and benefits , along with the safety-enhancing operational capabilities of the HydrOMac ® LH 2 refueling nozzle , make it a very intuitive product to use . The elimination of any ambiguity in its handling or operation allows LH 2 sellers to create a dispensing process that mimics the ‘ culture ’ of traditional vehicle fueling , helping to ease any concerns consumers may have when dispensing an unfamiliar fuel .
The HydrOMac ® LH 2 refueling nozzle is the latest addition to the RegO and OPW CES product portfolio of hydrogen-handling products , which includes gate and globe valves , relief valves , regulators , HP master valves , check valves , and angle relief valves .
The HydrOMac nozzle has been designed as a robust LH 2 transfer and dispensing solution that replicates a safe and reliable , diesel-like handling and dispensing experience for the consumer .
