ALGAS-SDI is an ISO 9001 Certified, global company with credentials that date to 1932. We hold internationally recognized certifications or approvals including FM, UL, CSA, CE, ATEX, DEMKO, ASME, PED and others. We employ nearly 100 people with stocking distributors, agents and partners in 67 countries. Our North American network alone includes 74 distributor locations in the USA, Canada and Mexico. Our corporate headquarters and primary manufacturing is located in Seattle, Washington. Additional manufacturing facilities are located in Queretaro, Mexico. Algas-SDI branded products go to market via two internal divisions: LPG Distributed Products and Engineered Systems. Our Distributed Products Division manages the application and sales of standard, pre-engineered, small to medium capacity LPG vaporizer and tank heater products. Our Engineered Systems Division originated before WWII to manage the design and sale of customized and large capacity LPG products and complete Synthetic Natural Gas systems. SNG is a blend of LPG vapor and air mixed to a specific ratio allowing interchangeability with natural gas. An SNG system represents to the natural gas grid user what a generator represents to the power grid user. At their elemental level, both an SNG System and a generator are tools used when a planned or, more likely, an unplanned event interrupts the respective utility. visit www.algas-sdi.com
