Product Features

Full radius nozzle tips

The series internally heated nozzle systems offer many advantages over their externally heated counterparts. With no exposed components and a sealed design constructed of stainless steel they are one of the most durable nozzles available. Blowing a bonnet, or polymer buildup of the nozzle body has little to no effect on the nozzle's operation or efficiency. All of these attributes combine to provide a very real saving in time and money.

Maintenance Free Operation

The precision manufacturing and stout construction provides for long term maintenance free operation, even the most challenging environments. It's completely sealed design allows for buildup of polymers around the outside

with no impact to function or performance. As well, this reduces the need for maintenance personnel to perform the messy, time consuming and sometimes dangerous processes of replacing the heaters and cleaning the nozzle.

High Quality Construction and Materials

All steel parts are manufactured from Ningbo DW Machinery's very tough and high strength steel alloy.

This alloy combined with a custom heat-treat process created an incredibly wear and corrosion resistant assembly.

Precision Machining

All pieces are CNC machined with ground seating and sealing surfaces. The internal flow surface is honed and highly polished to 16/32 RMS. A smother flow surface allows for faster purging, color changes and more consistent operation.
