 Hot melt adhesvie supply hoses are electrically-heated, flexible conduits designed for the transfer of hot-melt material from an adhesive supply unit (ASU) to an applicator (head or handgun). Hoses are heated by resistance heaters which are wrapped around the hose core and covered with a high-temperature insulation. Hose temperature is regulated by the ASU's controller. A sensor located in the hose provides temperature information to the controller.
GEMINI DYNACONTROL are 1000 psi (69 bar) hoses used to deliver
hot-melt material from a Dynamelt or Dynamini ASU to an ITW Dynatec
applicator (either a dispensing head or a hand-held applicator). These
hoses provide through wiring for power, sensor and chassis ground in
the applicator. All DynaControl hoses feature PT-111 RTD sensors.
Gemini
hoses are equipped with an extra heater and RTD sensor and a switch
assembly which allows the operator to switch the hose's operation
between the two. This provides a backup to eliminate downtime and
allows time to plan for eventual hose replacement
Gemini
hoses are water-resistant, made so by their seamless flexible sleeving,
sealed end cuffs and liquid-tight electrical conduit and fittings.
 
Meet the hot melt hose that won’t stop a production
line…the new Gemini™ Hose with Run Fail™ Technology. The Gemini hot
melt hose gives your customers the insurance that a hose heater or
temperature failure won’t shut down their production line.
All
Gemini™ Hoses incorporate dual heaters and dual temperature sensors
along with a switching means to select between the first and second
circuits.
Gemini™ hoses are available for Nordson equipment.
It
takes about 45 minutes to replace a hot melt hose. The 45 minutes
includes trouble shooting, obtaining the correct hose from the parts
room, removing and replacing the hose and getting the system back up to
operating temperature. If the line down time is $600 per minute then
the costs to replace a hot-melt hose is $27,000.
If your company has replaced only 5 hoses annually that’s a $135,000 annual down time production penalty.
It's
time to replace the Gemini™ adhesive hose with a new Gemini™ adhesive
hose when the hose is switched to the secondary circuit. The hose has
paid for itself and it’s time to install a new Gemini™ hose with
secondary circuit insurance. If the hose isn’t replaced it’s just
another hose without the dual circuit technology. The replacement
should take place at the next scheduled line down-time.
