Light tracing (TPL) places a measure of insulation between the steam tracer and the process tube. It is generally used to provide freeze protection for instrument impulse lines and process lines for analyzers. Light steam tracing provides protection over a longer length than than heavy traced designs.

O'Brien TRACEPAK tubing bundle consists of a small diameter tube or group of tubes packaged in an insulated, weatherproofed jacket. It may be steam or electric traced to provide freeze protection or temperature maintenance. O'Brien tubing bundles provide the most economical and dependable solution for permanent installations. Whatever your application

Maintains freeze protection, close temperature tolerances or viscosity control. Excellent for maintaining long, continuous lengths of impulse lines and piping at consistent temperatures. Good for situations where steam is not available or steam supply could be interrupted, such as during shutdowns.

-LINE® is used in applications where additional protection is required. J Line is not insulated or heated. J-Line tubing is ideal for pneumatic and hydraulic applications. Industry standard tubing coated with O’Brien SV47 polymer provides increased protection cushioning the tube against wear from vibration. J-Line is supplied in long continuous coils that eliminate intermediate fittings every twenty feet (six meters). This reduces the number of potential leaks points in a single tubing run from 50 to over 90%. Uses • Instrument air • Pneumatic process control lines • Municipal water wells • Down-hole chemical injection • Chemical injection • Seal water feed lines • Direct burial • Windblown sand

Six sizes With a choice of six sizes you can select a steam heater that will provide freeze protection in the winter without overheating the instrument in the summer. Freeze protection or temperature maintenance These heaters have been thoroughly tested in our in-house environmental chamber to verify design calculations so that reliable predictions can be made for both low and high ambient conditions. If you need to maintain precise temperatures you can use the heater control valve (HCV) to control the enclosure temperature. It is available with standard 50°F (10°C) and 100°F (40°C) set-points. It can also be ordered for special set-point requirements. Corrosion resistant and efficient Constructed from stainless steel tubing and carbon steel fins, each unit is coated with a nickel-chrome alloy after assembly. O’Brien steam heaters combine corrosion resistance and heat transfer efficiency in one unit. Simple connections and installation Stainless steel mounting hardware is standard with all steam heaters. They fasten the heater to the instrument mounting bracket in the enclosure. The U-bend shape of the heater simplifies connecting the steam supply and condensate return to the 38" NPT fittings.
