Packaged Gas Applications
Chart’s packaged gas systems serve a wide array of applications and industries, including:
Welding – GMAW/MIG, GTAW/TIG and Laser Beam Welding
Metal fabrication uses many different welding processes for the wide range of materials, thicknesses and product applications. Many of these unique and specialized welding processes use inert shielding gas or the combination of gases to obtain maximum weld quality with optimized productivity. Liquid cylinders offer the flexibility to easily alter the gas supply to match the manufacturing process changes.
Cutting – Laser, Oxy Fuel and Plasma
All thermal cutting techniques utilize gases to assist in the cutting process. High-pressure nitrogen and oxygen are used as an assist gas to rapidly remove the molten metal from the cut zone or burn it away during the laser cutting process. To maintain maximum laser uptime and achieve the best cut quality, it is critical that the gas supply be uninterrupted and the required pressures and flows for the material and thickness being cut are maintained. Oxy Fuel and Plasma cutting processes have similar requirements. Laser-Cyl liquid cylinders manifolded together are an economical solution to providing an uninterrupted gas supply.
Heat Treating – Cryotempering - Thermal Spray Coating
Heat treating and cryotempering processes are dependent on the quality of the nitrogen gas and liquid supply to maintain production at peak performance. With the Dura-Cyl located at the point of use, the operator has complete control over their gas supply for optimum operation. In the thermal spray coating process, oxygen and argon are used at high pressure and at high flow rates. Manifolding Dura-Cyl tanks together is an economical solution for this application.
ICP/ICP-MS – Inductively Coupled Plasma/Mass Spectrometry GC – Gas Chromatograph
A continuous flow of high purity argon gas is required for ICP/ICP-MS systems to repeatedly process material samples trouble-free. Dura-Cyl liquid cylinders manifolded together meet this requirement. In addition, liquid cylinders are compact so they take up a minimal amount of valuable lab space.
Biological Storage and Research
A sufficient supply of high-quality liquid nitrogen is needed to keep valuable biological samples stored indefinitely.
Any interruption in supply can result in the loss of many years of research. With dedicated Dura-Cyl liquid cylinders connected to your equipment, you can be assured of your liquid supply to keep your samples safe. For applications that require the greatest amount of liquid in a tight space, the Dura-Cyl 265 with casters is an excellent choice.
MRI – Magnetic Resonance Imaging (Helium)
Superconducting magnets bathed in liquid helium are the most commonly used magnets in an MRI machine. The low temperature reduces the internal resistance to zero, which reduces the electrical requirement for the system dramatically and makes it much more economical to operate. Chart's Ultra Helium Dewars are designed and built for reliable helium transport. They are thermally efficient, lightweight and maneuverable – making them the dewar of choice of lab personnel.
Oxygen Therapy – Cryotherapy
Medical applications have some of the most stringent gas specifications and the Dura-Cyl meets these requirements with NF grade availability. Dura-Cyls manifolded together for respiratory therapy assures a continuous gas supply and lowers distribution costs over high pressure cylinders. An isolated hyperbaric chamber with intermittent use of oxygen is also a good application for Dura-Cyls. NF grade nitrogen can also be supplied for gas applications to operate pneumatic surgical tools and supply liquid for medical uses such as cryotherapy.
Purging and Blanketing
Inert purging and blanketing with nitrogen or argon gas is a common processing step in many manufacturing applications. These range from pharmaceutical to chemical to wine making. Other unique applications like keeping fiber optic and telephone wire lines dry with nitrogen throughout the city make the Dura-Cyl an excellent choice of inert gas supply.
Electronic Manufacturing and Testing
Electronics manufacturing can use liquid or gaseous nitrogen or argon during the manufacturing process. Dura-Cyl liquid cylinders offer a compact package where the pressure and source is near the operation for convenience and customization of the gas supply. In a related business, printed circuit board testing (HALT/HASS) performed with liquid nitrogen-powered environmental test chambers requires quality liquid at the point of use. For intermittent users or small chambers, the Dura-Cyl is an economical and convenient liquid supply.
