CNC Products

We have been successfully manufacturing cryogenic equipment at Technifab since 1992. During that time, we were in the need of CF and KF flanges. We were unable to find the quality that we demanded for our products so we started our own CNC shop. Since then, we have created high quality CNC products such as flanges, nipples, elbows, tees and more. We know you will be satisfied with our quality, service, and delivery because we are our own toughest customer.

Liquid Nitrogen Dewars

Features

Technifab dewars combine an advanced vacuum
design and super insulation to achieve superior
thermal performance.

The high strength aluminum material, ribbed
cylinder, durable neck-tube, and convenient
handle provides you with a liquid nitrogen dewar
that is lightweight, rugged and easy to use.

Each dewar is performance tested prior to
shipment and fully warranted with serial number
tracking documentation.

Benefits

The superior thermal performance of Technifab dewars results in longer hold times, meaning less refilling and lower operating costs.

Made in our own facility, we can deliver dewars and accessories from stock.

The durable construction and ease of use ensures a convenient and long lasting device to store and transport liquid nitrogen.
