Dual module applicator head with heater controlled by RTD sensor. H200 Zero Cavity Style modules (KNH2CZCXX) are used on this applicator head for very precise applications with no stringing. This applicator head has common air which allows both modules to fire simulaneously using one solenoid valve (sold separately). Applicator head will fit to Nordson® 2300/3000/ProBlue® and DuraBlue™ standard automatic hoses.
