Dual module standard applicator head with heater controlled by a RTD sensor. H200 Style air open/air closed (AO/AC) modules (KNH44C) are used on this applicator head. Applicator head is independent air which allows two solenoids (sold separately) to fire the two modules separately. Applicator head will fit to Nordson® 2300/3000/ProBlue® and DuraBlue™ automatic hoses. Uses KNRN238 retaining nut for nozzles requiring retaining nut and KNH44C modules.
