This high-volume proportioner features 140 size pumps to deliver spray foam at 50 pounds per minute. It is designed to heat material quickly and maintain temperature set points even when spraying at maximum flow rates. It also allows the user to control material temperature in three heating zones for improved yield. A pressure imbalance control prevents off-ratio conditions and a programmable standby mode shuts the motor and hydraulic pump down after a period of inactivity reducing system wear and preventing the unit from overheating.
