Self-Adjusting Ratio Control for Low-Pressure Spray Foam Systems

No matter what spray foam system you use, being on-ratio is key for the chemical to mix – like the way the material supplier intended. Graco In:Pulse will help provide better yield and on-ratio product and eliminate the need for calibration.

In:Pulse provides real-time volumetric ratio control. Throughout the day, as the ratio mix changes due to ambient conditions, tank pressures, nitrogen pressures, etc., In:Pulse will self-adjust to ensure you spray on-ratio – every time.

How it Works

  1. Display Module: Compares ratio of the “A” and “B” chemicals and makes adjustments on the fly to keep you in control
  2. Pressure Regulator: Adjusts "A" chemical pressure to keep you on ratio
  3. Flow Meter (A side): Measures the flow of "A" chemical
  4. Flow Meter (B side): Measures the flow of "B" chemical
InPulse Ratio Control for Low-Pressure Spray Foam Systems

Low pressure (LP) spray foam systems play an instrumental role to an insulation contractor. LP systems are typically portable, convenient, and at times a more cost effective solution than sending out a high pressure rig. LP systems are ideal for some small, touch-up and repair jobs, as well as some in-plant foam applications.
