| About Helium |
You get more than equipment with a BOC Gases helium supply system. Getting the right capacity, dimensions and pressure of your helium storage tubes is clearly critical in the system design. Naturally, it's our job to assist you in selecting the optimal configuration.
BOC Gases, however, goes further. By auditing your process requirements, we help manage the entire gas delivery system. We have secured long-term product source guarantees, and designed an optimal network of production facilities. This translates into uninterrupted supply for you! BOC Gases has been able to reduce wasted gas, prevent safety hazards, and even improve process dynamics for our customers. All of this translates into unexpected savings for you. Consider what the cost would be of not using BOC Gases!
The BOC solution for gas helium supply is an integrated approach that takes little for granted. It reflects the right product purity, the correct equipment and controls and a detailed concern for safety. |
| The BOC fleet |
The ultramodern BOC Gases tube trailer and skid fleet provides exceptional flexibility for meeting the full scope of process requirements, delivering a wide range of equipment options. BOC Gases can secure tube units customized to your specific process and space needs. We can also provide separate skids for gases of different qualities. |
| ISO 9002 certified quality |
When you work with BOC Gases, you work with a supplier whose quality system adheres to the globally recognized ISO 9002 standard for manufacture and distribution of helium in a wide range of purity grades. Our main production facility in Otis, Kansas, was ISO 9002 certified by Lloyd's Register Quality Assurance in 1994. |
| Safety first, safety always |
BOC Gases production and delivery professionals assure that each unit which supports your process has been inspected and validated to internal standards - standards that typically exceed industry and regulatory requirements. As your partner, we understand that your lost time is our lost time, so we routinely inspect each storage unit delivered to your site to ensure safety and reliability. We can also provide validation services to ensure the safety of your own storage units. We support your safety efforts with on-site training programs offered by BOC technical experts, who can help assure that your personnel receive the most upto-date information about procedures and techniques for the proper storage and handling of helium. |
| Customized process solutions |
To ensure that your process continues running optimally, experienced BOC Gases engineering professionals will work with you to customize purity, service pressure, flow rates and site access.
We can develop a customized cost package to help you reduce costs through our liquid supply and gas recovery systems.
To ensure that optimal capacity is designed into your process, we can provide an advanced software tool that accurately determines gas volume, based on pressure, temperature and water volume factors.
BOC software provides a custom, traceable volume determination. We will consult with you about site safety, helping to establish effective measures to ensure reliable, worry-free operation. With our exclusive Tel-Tank telemetry monitoring system, BOC Gases will customize a reliable, computer-controlled capability for automatic reordering so your process can continue at full, uninterrupted productivity. The Tel-Tank telemetry system can also be configured to initiate an alarm that will alert your personnel to lowpressure or low-volume conditions. |
