Internal Gas Traps
Our internal gas traps reduce frosting when equipment is not in use. The gas trap ‘traps’ a pocket of gas inside the line when the use point or the supply line is shut-off. The gas pocket prevents liquid nitrogen from reaching the nonvacuum jacketed tubing, allowing the connection to defrost when not in use.
Key Features And Benefits
- Reduction in Heat Leak: When liquid nitrogen is not flowing, the heat leak of a non-vacuum jacketed termination is about 200 BTU/hr (59 watts). With an internal gas trap, the heat leak is reduced to about 0.5 BTU/hr (.1 watts).
- Reduces Ice: When liquid nitrogen is not flowing, your non-vacuum jacketed terminations will drip and form an ice ball. With an internal gas trap, this ice ball disappears.
