The NST-3M Series Thermodynamic Steam Traps with built in strainer are suitable to use in pressure upto 42 Bar. These traps intermittantly discharge condensate with a blast action at a few degree below steam saturation temperature.
INSTALLATION
Before install the trap NST-3M, blow out all dirt and scale from pipe line. Install the trap in the direction of arrow on the body as close as possible to the apparatus of drainage. Pitch all drain lines toward trap. Use a valve before trap for easy maintenance.
MAINTENANCE
