Technifabs TS Series tank switchers provide continuous liquid nitrogen supply by automatically switching from the empty dewar to a full dewar. The TechniSwitch Tank Switchers are available in either a non-vacuum jacketed or vacuum jacketed version. The VJ unit offers low heat leak, minimal boil-off, no condensation, touchable casing and eliminates solenoid chatter. It is the most efficient and safe switcher in the industry.

Benefits

Reduces operating expenses by minimizing employees involvement in tank changeover.
Saves money by reducing system downtime during dewar replacements.
Empty tank alert and dry contact for customer provided alarm.
Additional benefits of the VJ version:

Improves environmental safety by eliminating pipe dripping and reducing slip hazards.
Reduces workplace hazard because outer casing is touchable.
Uses less liquid nitrogen through quicker cool-down enabling faster deliver to end use points.
Features

Allows a variety of different tanks and VGLs.
Easy operation using touch screen PLC controls with simple adjustment.

The high thermal performance of Techniguard R-Series rigid vacuum insulated pipe often saves our customers enough liquid nitrogen to pay for itself in less than a year. Our rigid pipe is maintenance free and warranted for ten years!
Delivers significant lifetime savings due to minimal cryogen loss.
Easily accommodates future expansions or modifications.
Provides longer, care-free service life, backed by our best-in-the-business warranty.
Provides a rapid return on your investment.
Easy Installation manufactured in easy-to-assemble sections with high-efficiency, low heat leak bayonet connections. No welding or refitting in the field required, its even easier to install than foam covered pipe!
Doesnt need expensive vacuum pumps that require maintenance like dynamic vacuum-jacketed systems.
ASME certification and CRN (Canadian Registration Number) are available.

From bulk transfer hoses to stingers, Technifabs complete line of low heat-leak liquid helium transfer equipment
provides safe and efficient transfer of liquid helium.

We design and manufacture:

Helium transfer hoses unsurpassed in efficiency, meaning less helium loss to your equipment.
Cryostat and Dewar stingers available in a variety of standard configurations or custom made to your application.
Vacuum Jacketed LHe valves can be incorporated into our products or sold as stand alone items.
Manifolds built in any practical configuration. Common examples are liquid helium transfill stations where LHe is transferred from tanker truck to dewars for distribution.
Dewar fill hoses
Diptube extensions

Technifab offers a line of vacuum jacketed valves that gives you top cryogenic valve performance and also work best with vacuum jacketed pipe. These low heat leak vacuum insulated valves dont add unwanted heat to your cryogenic liquid, saving you money and loss of cryogens.

Benefits
Vacuum-jacketed, eliminating icing and condensation seen with non-vacuum jacketed cryogenic valves.
Self-aligning, PCTFE seat designed for flexibility and solid closure at cryogenic temperatures.
Wear parts are easily replaceable reducing down-time.
Redundant cryogenic bonnet seal provides an extra level of safety.

Technifabs WhisperTech line of exceptionally quiet detector dewars can cover the entire electromagnetic spectrum. Detector dewars are used to reduce the temperature of an electromagnetic sensor and the first stage amplifier, often a field effect transistor. By reducing the temperature the noise level of the components are exponentially reduced. Thus a cleaner, better signal comes out of the detector used in the product.

WhisperTech line of detector dewars are constructed to the highest quality standards. Whatever tolerances you specify, our quality assurance program will ensure conformance on each and every unit. We understand the importance of reducing microphonics and will work with you on design and processes to deliver to you noise-free dewars.

Over the years we have developed a reputation for high quality and competitive prices. Whether the detector is for X-rays or Infrared radiation, undesirable thermal and vibratory mechanical noise is held to a minimum by using the Technifab manufactured dewar.

Internal Gas Traps are typically installed in vertical drops to liquid nitrogen use points with non-vacuum jacketed terminations. The gas trap works by trapping a pocket of gas inside the line when liquid nitrogen is shut-off. This gas pocket prevents liquid nitrogen from reaching the non-vacuum
Benefits of using a gas trap include:

Reduced Heat Leak When liquid nitrogen is not flowing, the heat leak of a non-vacuum jacketed termination is about 200 BTUhour
(60 Watts). With an internal gas trap the heat leak is only about
0.5 BTUhour (0.15 Watts).
Eliminates Ice. When liquid nitrogen is not flowing your
non-vacuum jacketed terminations maintain a constantly dripping
ice ball. With an internal gas trap, this ice ball disappears.
