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.
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 don’t 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.
Technifab’s 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.
