Materials
A quick and easy “in-line” replacement for other types of side inlet/side
outlet traps, the Armstrong 1800 Series brings together all the benefits
of energy-efficient inverted bucket operation. Side inlet/outlet all-welded
construction means an inverted bucket trap that will operate efficiently
on applications such as tracer lines, drips, heating, processing and
similar applications.

Pop Drain for Freeze Protection
In general, a properly selected and installed Armstrong trap will
not freeze as long as steam is coming to the trap. If the steam
supply is shut off, a pop drain should be used to automatically
drain the trap. Stainless steel pop drain available for Models
1811 and 1822.

Insu-Pak™
Now you can insulate the in-line traps in your plant without
complicating regular trap maintenance. Insu-Pak, a simple
reusable insulation package, cuts the time and cost of in-field
installation because it goes on in a snap. And it comes off just
as easily. Insu-Pak can prevent trap freeze-up when used with a
properly designed condensate manifold. Designed for use with
Model 1810 and Model 1811 traps.
Probe connections are available for trap monitoring on Models
1811 and 1822.
All dimensions and weights are approximate. Use certified print for exact dimensions. Design and materials are subject to change without notice.
