Fenix hydrodynamic steam trapAM

Process · NPT / BSP thread · ½" to 1"

The AM trap is designed for process applications where screwed connections are used. A screwed union is required downstream to remove the trap for cleaning. A high integrity strainer is part of the design, with an optional drain valve for periodic cleaning.

01

Built for process

Process trap with screwed connection and a high integrity strainer built into the design.

No moving parts

Works on a hydrodynamic principle with sized venturis. There is no disc, float or bimetal to wear out.

High integrity strainer

CF8M cast strainer with 40 mesh screen and 10 mesh reinforcement.

Easy to remove

With a screwed union downstream, the trap comes out for cleaning. Optional drain valve for the strainer.

Full load range

Works from minimum to maximum flow rate of the application.

A

Shell and tube heat exchangers

Condensate discharge from the steam side under variable load.

B

Air heaters

Steam coils and batteries heating process air.

C

Calorifiers and reboilers

Process equipment with variable steam demand.

D

Cooking vessels

Jacketed vessels with heating cycles.

Frequently asked questions

What maintenance and engineering teams ask us most about the AM trap.

What applications is the Fenix AM steam trap designed for?

Process applications with screwed connections, such as shell and tube heat exchangers, air heaters, calorifiers and cooking vessels. It works over the full range of the application, from minimum to maximum flow rate.

What is the maximum operating pressure of the AM?

AM: 435 psig (30 barg) at 500 °F.

What sizes and connections does the AM come in?

½" (DN15), ¾" (DN20), 1" (DN25). Connections: NPT or BSP thread.

How is the AM maintained?

A screwed union is required downstream to remove the trap for cleaning. The optional drain valve allows easy strainer cleaning (recommended up to 20 barg).

What warranty does the Fenix AM trap have?

The Fenix AM trap has a 15-year warranty. Its strainer, designed and made by Fenix, is also guaranteed for 15 years.

Why does the trap strainer matter?

Particles carried by the steam, such as rust, weld slag and scale, can block the nozzle. A robust, efficient strainer keeps the trap working properly. That is why Fenix designed and makes its own strainer and guarantees it for 15 years.

What is the drain valve for?

It is an optional accessory that allows easy strainer cleaning. When opened, line pressure blows out the sediment held in the screen without opening the cap. It is recommended for traps operating at no more than 20 barg.

What spare parts are available for the AM?

Strainer filter (F-L), Cap gasket (G-4), Nozzle gasket (G-3).

07

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.

Protects the nozzle and venturis

Rust, weld slag and scale carried by the steam are among the most common causes of trap failure. The strainer holds them back before they reach the nozzle.

Robust by design

High integrity strainer: CF8M cast body and 40 mesh stainless steel screen with 10 mesh reinforcement. 304L stainless steel cap.

Cleaning without removing the trap

The screen comes out through its cap; the trap body stays installed in the line.

Optional drain valve

An accessory that allows easy strainer cleaning: when opened, line pressure blows out the sediment held in the screen without opening the cap. Recommended for traps operating at no more than 20 barg.

Trap and strainer from one maker

Both are designed and made by Fenix, and both carry a 15-year warranty. No generic third-party strainer.

15year warranty on trap and strainerThe strainer carries the same warranty as the trap.
