Steam Trapping and
Steam Tracing Equipment
The Armstrong CD-72S/SL is a disc style trap designed to control
the trap’s cycle rate. By reducing the cycle rate, the Armstrong
CD-72S/SL will have a longer service life than typical disc traps.
This enhanced performance will ensure that maintenance time is
minimized and steam costs are greatly reduced.
The CD-72S/SL is designed with three discharge ports, which offer
stable disc operation to extend trap operating life. The capacity of
the Armstrong CD-72S/SL has been engineered specifically for the
following applications: large steam main drips, process equipment,
and HVAC heating equipment on constant pressure.
