Application
Suitable for light to medium condensate loads: steam tracing, steam main drips, small heat exchangers, unit heaters, sterilizers and many other applications in the petrochemical, chemical, textile, food, pharmaceutical and further industries.
| S31N | Ductile Cast Iron Steam Traps with replaceable internals |
| SC, SF | Cast Iron Steam Traps for high capacity |
| SU2N, SD1 | Stainless Steel Steam Traps for high pressure applications |
| S55N, S61N, S62N | Forged Steel Steam Traps for high pressure applications |
Features
| Immediate discharge of condensate |
| Insensitive to waterhammer, superheated steam and freezing |
| Use of a bimetal ring to improve the ability of the trap to discharge air and cold condensate quickly at start-up and prevents air locking during times of operation |
| Can be installed in any position |
| Equipped with additional cover for reduced frequency of cycling and energy savings |
| All traps have inbuilt strainers |
Operation
| 1) Cold Condensate: At the time of start up the pressure of the incoming cold condensate and air raise the disc and water and air are discharged quickly. |
| 2) Hot Condenstate: When hot condensate flows into the trap, the trap is still open and the hot condensate can be discharged quickly. |
| 3) Steam: After hot condensate flows into the trap, steam enters it. As the velocity of the fluid increases, the pressure under the seat exerted by the steam decreases. At the same time the pressure in the pressure chamber above the disc increases. The disc is pressed down and closes. |
| 4) Hot Condensate + Steam: While hot condensate flows into the trap, the trap remains closed for a certain period, as far as the steam inside the pressure chamber does not condense. The more condensate flows into the trap, the more the temperature cools down. The steam inside the pressure chamber also cools down and condenses. As a result, the pressure of the incoming condensate raises the disc and condensate is discharged. Cycles 2, 3 and 4 repeat. |
