Description

Watlow's K-Ring® nozzle heater takes technology a step ahead of the competition. Thanks to its innovative design, plastic molders no longer have to compromise with sloppy fit tolerances, uneven temperature profiles, or short heater life. Featuring a machined brass casting construction, the Watlow K-Ring® nozzle heater can handle very high temperatures while providing maximum heat transfer. With a precision machined inside diameter, the Watlow K-Ring® nozzle heater fits perfectly and doesn't even require clamping bands. Precision fit and the excellent thermal conductivity of brass allow the Watlow K-Ring® nozzle heater to give you an extremely even temperature profile.

Watlow K-Ring® nozzle heaters have operating temperatures up to 1200°F (650°C) and can generate watt densities up to 260 W/in2 (40 W/cm2). The brass casting construction and stainless steel outer casing protects the heater. Sealed construction of the heater body eliminates contamination. The adaptor also effectively seals the lead exit. Distributed wattage allows heat to be precisely placed for an even temperature profile. Heater efficiency can be increased with optional polishing of the stainless steel outer casing.

Applications of the Watlow K-Ring Nozzle Heater

  • Plastic injection molding nozzles
  • Sprue bushings in plastic molding equipment
  • Process heating of liquids and gases in processing lines
  • Hot melt equipment
  • Laboratory and analytical equipment
