Two Spray Foam Guns on a Single Proportioner

Many attempts have been made to use two spray foam guns on one proportioner, but not without complications Yes, splitting our HOSES is a risk. But Boss Spray tech has the solution. Boss designed and patented a fluid block with pressure balance cartridges which works with original factory-equipped pressure transducers. Boss has designed the position of our pressure balance cartridges to align directly with factory equipped pressure transducers in the fluid block. When a downstream restriction is present, the increased pressure influences back to the fluid block and must pass in front of the equipped pressure transducers, triggering an off-ratio alarm and proportioner shut down. Boss also includes an independent hose heat box transformer and temperature controller. 

This system is recommended only for experienced spray foam contractors with over 6 months to one year's field experience. Contact Profoam to discuss adding one of these systems to your rig.


Enjoy lower capital costs of adding a second gun without:

  •  Second Proportioner
  •  Larger Barrel Pumps
  •  Larger Compressor
  •  Higher GVW Box Truck or Trailer
  •  Larger Gen Set

BTG also includes an independent hose heat box transformer and temperature controller
