HIGH-PRESSURE SPRAY FOAM SYSTEM EXPLAINED
Professional high-pressure spray foam system explained services in Greater Houston, TX.
A-SIDE DRUM
The A-side is stored in its own drum and travels through a dedicated transfer pump, supply hose, proportioner pump, heated hose passage and gun inlet.
- Isocyanate Component
B-SIDE DRUM
The B-side is stored and moved through a completely separate material path. Its manufacturer-designed formulation determines whether the finished product becomes open-cell or closed-cell foam.
- Polyol Resin Blend
- Transfer Pumps Feed the Machine
- The Proportioner Meters Both Components
- The Proportioner Adds Heat and Pressure
- The Heated Hose Maintains Conditions
- The Whip Hose Connects to the Gun
- The Components Mix Inside the Spray Gun
- The Material Expands and Begins Curing
What the Proportioner Actually Does
The proportioner is the central processing unit of a high-pressure spray foam rig. Its job is not simply to pump faster. It has to move both sides together while controlling ratio, pressure and temperature closely enough for proper mixing at the gun.
- Meters the Ratio
- Builds Fluid Pressure
- Heats the Components
- Feeds the Heated Hose
- Supports Consistent Output
- Matched pumping systems dispense the A-side and B-side at the required volumetric relationship. A shortage on either side creates off-ratio material.
- High pressure helps drive both materials through the hose and creates the velocity required for impingement mixing inside the gun.
- Primary heaters reduce viscosity and bring each component toward the approved processing temperature for the selected foam system.
