Frequently asked questions
What maintenance and engineering teams ask us most about the FLSS trap.
What applications is the Fenix FLSS steam trap designed for?
Process applications on flanged lines, 1" to 4", such as shell and tube heat exchangers, air heaters, reboilers and cooking vessels. Each trap is designed for its location with flanges to match the system.
What is the maximum operating pressure of the FLSS?
FLSS: depends on the flange rating, from PN16 or ANSI 150 up to PN100 or ANSI 1500.
What sizes and connections does the FLSS come in?
1" (DN25), 1½" (DN40), 2" (DN50), 3" (DN80), 4" (DN100). Connections: ANSI or PN flanges.
How is the FLSS maintained?
The inlet nozzle is 316 stainless steel, and its gasket is supplied as a spare part by size (G-3 to G-6).
Can the FLSS be made in a special length?
Yes. It is made in standard lengths or custom up to 1000 mm (40").
What warranty does the Fenix FLSS trap have?
The Fenix FLSS trap has a 15-year warranty.
What spare parts are available for the FLSS?
Nozzle gasket (G-3 (1") · G-4 (1½") · G-5 (2") · G-6 (3", 4")).
Fenix strainer, designed and made by Fenix
A trap only works well if the condensate reaching it is clean. That is why Fenix designed and makes its own strainer, and guarantees it for 15 years, the same as the trap.
