Gas systems to meet your needs – standardized and tailored solutions for commercial and industrial applications.

Need a back-up for your natural gas?

Synthetic Natural Gas (SNG) Products

Need a back-up for your natural gas? Packaged SNG systems from Algas-SDI do it all. We also offer gas-air mixers designed and manufactured for industrial and utility applications, as well as liquid LPG pumps and accessories.



Compressed Natural Gas (CNG) Products

TRUXX portable and fixed CNG decompression stations make natural gas accessible, reliable, and easy to use for locations off the grid. Using the well-proven TRUXX CNG platform, we also offer trailer offloading, decompression systems for pipeline injection.



Renewable Gas (RNG) Products

Algas-SDI TRUXX systems are used to decompress CNG for pipeline injection of renewable natural gas (RNG).  Algas-SDI Consta-MIX™ systems are used to accurately blend two gas streams for augmenting the supply of digester gas to run standard and low emission stationary reciprocating engine generators, and for pre-mixing natural gas or LP-gas with air for combustion applications.
