BLENDAIRE LPG/Air Mixers 
  
  
  
Algas-SDI BLENDAIRE mixers accurately mix 2 gas streams at pressures up to 150 
PSIG for standard units and up to 250 PSIG for high pressure units. Standard 
packages are set up for LPG-air mixing to replace or augment the supply of 
natural gas for industrial back-up or for city gas (synthetic natural gas) 
production as a lead in to natural gas or for augmenting the supply of natural 
gas such as peak shaving. At the heart of the BLENDAIRE is the FVO 3-port mixing 
valve that automatically and accurately balances the orifice area for each flow 
stream according to flow rate. The process does not rely on feedback from 
electronic controls that can fail or go out of calibration. Operation of these 
units is simple and failsafe, relying on cross linked regulators to equally 
govern the pressure entering each side of the mixing valve. Valve port position 
and flow rate position indicators are provided for direct visual indication. 
  
This proportional mixer provides accurate LPG/Air mixtures within desired 
adjustable ratios and delivery pressures of up to 150 PSIG.
