Horizontal Insulated Pressure Systems
What Are Horizontal Insulated Pressure Systems?
A horizontal insulated pressure system is a double-wall pressure containment vessel oriented along its longitudinal axis parallel to the ground, featuring an inner pressure vessel surrounded by an insulated outer jacket with the annular space either evacuated to high vacuum or filled with specialized insulation materials. This horizontal configuration provides a low center of gravity for transportation applications, maximizes liquid surface area for enhanced vaporization rates, and enables efficient integration with trailer-mounted or skid-mounted systems. Horizontal vessels incorporate saddle supports and internal baffles to manage liquid movement during transport or process operations.
Why Choose Horizontal Insulated Pressure Systems?
Horizontal Insulated Pressure Systems offer several critical advantages:
- Transportation Compatibility: Low profile and longitudinal orientation ideal for over-the-road transport on trailers and railcars
- Enhanced Vaporization: Greater liquid surface area exposure promotes efficient natural vaporization for gas delivery applications
- Lower Center of Gravity: Horizontal orientation provides inherent stability for mobile and transportation applications
- Simplified Loading/Unloading: Side-mounted connections facilitate efficient liquid transfer operations
- Baffle Integration: Internal baffles control liquid surge during transport, protecting vessel integrity and ensuring stable operation

Frequently Asked Questions About Horizontal Insulated Pressure Systems
What transportation codes do horizontal insulated pressure systems comply with?
Our horizontal insulated pressure systems are designed and fabricated to comply with DOT, TC (Transport Canada), and international transportation codes including MC-338, CGA, and AAR specifications for cryogenic cargo transport.
How do internal baffles function in horizontal insulated pressure systems?
Internal baffles in horizontal vessels divide the liquid volume into compartments, reducing liquid surge forces during acceleration, braking, and turning. This protects vessel integrity, maintains stability, and ensures compliance with transportation safety requirements.
Can horizontal insulated pressure systems be mounted on existing trailer frames?
Yes, Roben Mfg designs horizontal vacuum-insulated vessels for retrofit onto existing trailer frames or integration into new chassis designs, with custom saddle configurations and connection locations to match specific platform requirements.
