Hot RunnerManifold <strong>Heaters</strong>Thick Film ManifoldApplications• Hot runner manifold systemsSpecifications• Maximum substrate temperatureof 550°C (1025°F)• Watt densities are applicationdependent over entire substratesurface• 5.43 W/cm 2 (35 W/in 2 ) for radiantheating applications• Up to 240 volts, three-phase• Termination options includecontact pad, soldered lead wire orwelded stud/lead wire (standard)Watlow thick film technology heatersoffer distinct <strong>com</strong>petitiveadvantages over tubular heatertechnology:1. Uniform thermal profile thateliminates hot and cold spots2. Low thermal mass allows forquick heat up and reducesthermal lag3. High dielectric barrier withagency approvals eliminatesneed for soft start4. Lower heater operatingtemperatures5. Precise and repeatable wattagedistribution6. Increased controllability of system7. Increased productivity throughdecreased set-up time8. More manifold design flexibility9. Simpler manufacturing byeliminating the need for traditionalmachined grooves10.Terminations can withstandtemperatures of up to 550°C(1025°F) and can be located innearly any location (moving themaway from areas where damagecan occur during normalmaintenancePrecise Wattage DistributionThick film manifold heaters rated to 550˚C (1025˚F) provide superiortemperature uniformity by putting the energy exactly where it is needed.144
