Options 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.

Model 1822 Capacity Body O-Ring Spring Pressure, bar 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.
