Syntactic Natural Gas (SNG)

Synthetic Natural Gas systems can be used to augment or completely replace piped natural gas, compressed natural gas or liquefied natural gas to manage outages, interruptions in supply or to capture price advantages between different fuel types. BANGLAMARK offers complete solution of Algas-SDI who manufactures a complete range of natural gas replacement systems for industrial and municipal applications, including hospitals, schools, military bases and emergency shelters. Large utility systems are designed and manufactured for LDC peak load shaving after the city gate. Systems can be supplied in either high or low pressure configurations with high pressure systems requiring a compressed air source. Algas-SDI has the widest range of vaporizer options available from direct gas fired, to gas fired waterbath to full dry electric vaporizers that can be turned on and ready in less than 60 seconds. Environmentally, propane air is a clean alternative to backing up your fuel energy needs.

XPV Packaged Propane-Air Mixing System

XPV systems are self contained units that provide a natural gas compatible mixture of propane and air or LPG vapor and air. These systems are supplied with a dry electric vaporizer and a venturi mixer. An accumulator tank enables the venturi to cycle on and off to meet the required load allowing 100% turndown. Operation is quiet, reliable and safe.

XPV compact LPG-air mixing systems are available in various propane and LPG models providing gas/air mixtures from 2.5 – 28 million BTU/Hr at pressures from 5-12 PSIG atmospherically. A liquid pump, such as the Algas-SDI STABILAIRE may be required to provide sufficient gas pressure for the mixing process.

  • Compact unit incorporates XP electric vaporizer, venturi mixer, and surge tank for ease of installation and operation.
  • Explosion-Proof design allows the unit to be placed directly adjacent to the propane supply tank.
  • System provides 100% turndown capability and is available in mixed gas delivery pressures of 5, 8, and 12 PSIG.
  • Venturi silencer promotes quiet operation
  • Perfect for confined space applications and those requiring additional security – schools, bakeries, general industry – these systems are explosion proof and take up very little space.
  • Ready to operate in 1 minute from a cold start
  • Systems up to 12 psig discharge pressure do not require compressed air
  • Can be used with LPG — discharge pressures vary. Contact factory for more information.
  • ASME constructed surge tank with “U” stamp
  • FM Approved
  • Available in most voltage configurations
  • Capacities: 5 – 28 MMBTU/hr

XPM Electric LPG-Air Mixing System

  • Integrated unit comprised of an XP electric vaporizer and matching venturi mixer.
  • This unit is similar to the XPV system but does not include an integrated surge tank, thus permitting connection to a locally supplied surge tank.
  • The vaporizing section transforms incoming liquid LPG to the vapor phase, while the venturi assembly mixes the vapor LPG with atmospheric air to produce a natural gas compatible air/gas mixture
  • Systems available for use with commercial grade propane and propane/butane mixtures (LPG)
  • FM Approved
  • Capacities: 2.5 – 14 MMBTU/hr

DFV Packaged Natural Gas Replacement System

DFV propane-air mixing systems from Algas-SDI are self contained units providing a mixture of LP-gas vapor and air which can replace natural gas. These compact systems are available in a variety of sizes ranging from 2.5 – 42 million BTU/Hr at delivery pressures from 5 to 12 psig atmospherically. DFV systems use the Algas-SDI Direct Fired vaporizers and the Algas-SDI atmospheric venturi system packaged together with an ASME constructed accumulator tank. The gas is mixed with air in the venturi and stored in the accumulator tank to provide uninterrupted flow of mixed gas from full flow to zero flow, automatically.

A liquid pump such as the Algas-SDI STABILAIRE pump system may be required to provide sufficient gas pressure for the mixing process.

  • 100% turndown means these units are perfect for variable or steady loads
  • Economical solution to lower gas bills
  • Ensures your plant or facility will never be without gas
  • 110V/50-60Hz or 220V/50-60Hz
  • Electrical consumption less than 1 amp
  • Gas fired vaporizer with electric control system
  • Systems up to 12 psig discharge pressure do not require compressed air
  • Capacities: 2.5 – 42 MMBTU/hr

QM Packaged Propane-Air Back-Up System

The Algas-SDI QM natural gas replacement system is a combination gas fired waterbath LPG vaporizer and atmospheric venturi LPG/air mixer. All QM models feature an Eclipse Combustion ThermAir forced draft burner and Algas-SDI optimized venturi mixers. Operation of these units has been proven in -40 F climates. PLC controls with an easy to use operator interface are provided in a temperature controlled enclosure to ensure long-term reliable operation. A “Smart-Start” cold start feature automatically senses and controls the inlet propane pressure to make sure only vapor is fed to the burner until the bath is warm enough for full vaporization. When the bath has reached operating temperature an output is switched by the PLC that turns on the LPG pump (STABILAIRE). A maintenance program tracks the hours used, venturi cycles, and burner cycles to allow the user to schedule service accordingly. Flow totalization is also provided for convenience.

  • Compact system comprised of vertical waterbath vaporizer and atmospheric venturi mixer
  • A forced draft burner keeps the waterbath at optimum vaporizing temperature
  • Powder coated galvanized steel cabinet
  • Easy to use Operator Interface with PLC and smart controls
  • Integral heavy ends trap keeps the “gunk” out of the venturi controls
  • Heavy duty water pump provides circulation and prevents temperature stratification
  • Systems 100 million and larger use a single pilot operated venturi regulator for robust, consistent control and easy adjustment
  • Delivery pressures up to 15 PSIG available with commercial propane feedstock, up to 8 PSIG with butane rich LPG, and up to 40 PSIG with compressed air
  • FM Approved
  • Capacities: 28 – 150 MMBTU/hr
