TD2CA - Thermodynamic Steam trap

Sanitizer TD2CA Sanitary Thermodynamic Steam Traps

Incoming air and condensate flow through the trap body into the control chamber. Line pressure raises the disc off the seat, allowing complete discharge. When flashing condensate enters the cartridge, flow velocity increases, creating low pressure underneath the disc. Flashing condensate at high velocity strikes the inside wall of the disc chamber and is deflected to the top of teh disc, causing a pressure buildup. The disc is forced down onto the seat by this pressure inbalance. The trap remains closed as flashed vapor in the control chamber keeps the disc seated. Pressure inside the cap is not lowered until the trapped flash vapor condenses due to body radiation. Condensing steam lowers the pressure above the disc. Disc is then lifted and the cycle repeated.

Stainless steel disc is the only moving part. Low initial cost is less expensive than repairable technologies. Handles water hammer and superheat. Blast discharge quickly draws condensate and helps maintain system temperature. Resists both internal and external corrosion. Audible discharge cycle makes checking operation simple.
