TDT — Thermodynamic Steam Trap
Compact disc-type trap that operates on the pressure differential and flash-steam velocity across a single moving disc.
Product overview
A thermodynamic trap with one moving part, chosen where robustness and superheat tolerance matter more than continuous discharge. Small, light and able to work in any orientation.
The problem it solves
Distribution mains, headers and tracing lines carry relatively small but constant condensate loads, often outdoors and often at high pressure. A trap on that duty has to be tolerant of superheat, waterhammer and freezing, and simple enough to service in the field.
Working principle
Condensate lifts the disc and discharges. As the condensate approaches saturation it flashes, and the velocity of that flash steam across the disc face creates a low-pressure region that snaps the disc shut. The trap reopens when the flash in the chamber above the disc condenses.
