Dissolved acetylene gas 1. Purity 98% c2h2 2. Filling into welded cylinders 3. Welding, cutting, coating acetylene Dissolved acetylene gas Acetylene (c2h2) is not an air gas, but a synthesis gas generally produced from the reaction of calcium carbide with water. It was burnt in "acetylene lamps" to light homes and mining tunnels in the 19th century. A gaseous hydrocarbon, it is colorless, has a strong garlic odor, is unstable, highly combustible, and produces a very hot flame (over 3000&,161;&,227;c or 5400&,161;&,227;f) when combined with oxygen. Acetylene gas purity: >98% Package: 1l-80l acetylene cylinders Delivery time: within 30days after deposit Moq: 200pcs ( 420 pcs/20ft container) Main applications 1. Welding, cutting & coating Acetylen is the most effective and versatile fuel gas; c2h2 enabling manual applications such as welding, brazing, cutting, straightening or any other localised heating process. 2.

Balloon gas Helium is colourless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas group in the periodic table. Itsboiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions. Helium is the second lightest element and is the second most abundant element in the observable universe. Usages: 1. Helium is used as a shielding gas in arc welding processes on materials that at welding temperatures are contaminated and weakened by air or nitrogen. 22.3l/13.4l disposable helium gas tank
R407C Specifications Class: 2.2 (Non-flammable gas) Global Warming Potential (GWP): 1774 Ozone Depletion Potential (ODP): 0 Packaging Quantities: Disposable Cylinders: 1150 units without pallets / 900 units with pallets Refillable Cylinders: 800 units with pallets / 1034 units without pallets R407C Applications R407C is a zeotropic blend composed of difluoromethane (R32), pentafluoroethane (R125), and 1,1,1,2-tetrafluoroethane (R134a). Each component serves a specific function: R32 provides heat capacity. R125 reduces flammability. R134a lowers operating pressure. R407C is recognized as a long-term replacement for R22, sharing similar performance characteristics. It is widely used in air conditioning systems and non-centrifugal refrigeration systems for medium and high temperature applications, making it an ideal solution in a variety of HVAC setups.
Helium / argon mixtures are sometimes used for their higher heat characteristics. Gas mixtures, usually 25% helium and 75% argon are sometimes used and can help to increase travel speeds when AC - gas tungsten arc welding.

R-123 Refrigerant (Hydrochlorofluorocarbon) Overview: R-123 was specifically developed as a replacement for R-11 in low-pressure centrifugal chillers. It is widely used in modern systems engineered with the correct materials and sizes to meet specific cooling needs. However, retrofitting existing R-11 chillers to R-123 may require replacing certain components like seals, gaskets, and other system parts to ensure proper operation and avoid leaks. Key Features: ASHRAE Safety Rating: R-123 has an ASHRAE rating of B1, meaning it has low toxicity but requires more stringent safety measures. Lower personal exposure levels are allowed during normal daily operation, but machinery rooms must follow specific requirements as per ASHRAE Standard 15 (Safety Code for Mechanical Refrigeration). Retrofitting Considerations: When converting from R-11 to R-123, modifications may be necessary, including the replacement of gaskets and seals to achieve optimal operational conditions and leak prevention. Low-Pressure Performance: R-123 is optimized for low-pressure centrifugal chiller systems, providing efficient cooling and performance in large industrial and commercial applications. Safety Requirements: Personal Exposure: Extra precautions must be taken due to the B1 rating, which permits lower exposure levels during service and daily operation. EPA Certification: An EPA certification card is required to purchase R-123 or any other CFC and HCFC refrigerants, in compliance with environmental safety regulations. Applications: Low-Pressure Centrifugal Chillers: R-123 is primarily used in large industrial and commercial systems, providing efficient cooling in these specialized environments. Retrofitting R-11 Chillers: It serves as an effective replacement for R-11, though retrofitting may require careful modification of existing systems.
