Techniguard® L-Series Piping
The Techniguard™ L-Series Pipe is a high-performance vacuum jacketed pipe designed to significantly reduce heat losses, boasting over ten times the insulation efficiency compared to traditional foam-covered pipes. Made from durable 300 Series stainless steel, it provides superior strength and corrosion resistance, making it suitable for various commercial cryogenic applications, including liquid nitrogen, CO2, argon, and LNG. Its low-maintenance design eliminates the need for external vacuum pumps, while embedded getter materials enhance its longevity. Available in straight lengths from 2 to 20 feet and in multiple inner diameters, the L-Series Pipe offers a range of installation kits and accessories for efficient setup.
Key Features And Benefits
- L‐Series vacuum jacketed pipe reduces heat losses by more than a factor of 10 compared to foam-covered pipe.
- Higher pressure rating for liquid CO2 and other cryogens.
- Embedded getter materials absorb outgassed molecules in the vacuum space, extending device lifetime.
- Pre‐built modules allow rapid configuration into a system when you need it.
