What Algas-SDI does

Algas-SDI International, LLC is a US-headquartered (Kent, Washington) private industrial manufacturer that designs and builds fuel gas vaporization, mixing, decompression, and combustion equipment for LP-Gas, natural gas, CNG, RNG, ammonia, and specialty gases. The company operates three internal divisions — Combustion Products (PHOENIX TH, VH, and SH burners), LPG Distributed Products (electric, gas-fired, waterbath, and steam/hot water vaporizers under brands including ZIMMER, TORREXX, POWER P, AQUAVAIRE, HYDREXX, AZEOVAIRE, and the acquired Dragon Shield line), and Gas Systems (TRUXX CNG decompression skids in E-, G-, and W-Series, SNG systems, gas-air mixers Consta-MIX, BLENDAIRE II, VAPORAIRE, and accessories such as FILTAIRE and GA500). Underlying technology is rooted in proprietary mechanical designs (Liqui-SAFE liquid carry-over valve, parallel-stream gas mixing, dry electric vaporizer heat exchangers) layered with PLC-based controls and an unusually broad portfolio of international safety certifications (ISO 9001, FM, UL, CSA, CE/PED, ATEX, ASME, CRN, IECEx).

The company makes money primarily through engineered-to-order hardware sales plus recurring professional services revenue from its VaporCare maintenance program. Pricing is quote-based and not publicly disclosed; standard warranty is one year, extended to two years for ZIMMER and single-core TORREXX vaporizers starting January 1, 2026. Distribution is hybrid: direct enterprise sales from US headquarters backed by a Global Support Center, plus an extensive channel network of stocking distributors, agents, and partners in 67+ countries, with 74 distributor locations across the USA, Canada, and Mexico. Manufacturing is split between Kent, Washington and Queretaro, Mexico. End-customers span industrial and municipal utilities, LP-Gas distributors, industrial combustion OEMs, renewable natural gas producers, and government/military buyers, with documented applications including Northeast US utility CNG peak shaving (62 MDth/day), digester gas augmentation at wastewater treatment plants, and emergency fuel backup for hospitals, schools, and military bases.

Founded through the 1999 merger of Algas Industries (itself dating to a 1932 direct-fired vaporizer patent) and Sam Dick Industries, Algas-SDI operates with roots going back more than 90 years, a headcount of nearly 100, and a global footprint reaching more than 87 countries. The company's most recent strategic move was the July 2024 acquisition of the Dragon Shield direct-fired LPG vaporizer product line, absorbing a competing brand into its LPG Distributed Products division.
