ARI CONA M – Thermostatic Capsule Steam Trap

The ARI CONA M is a thermostatic steam trap designed for draining steam in industrial installations. It operates via a membrane capsule that responds to condensate temperature and upstream pressure. It discharges subcooled condensate and automatically vents during startup and operation.

Variants and Operational Limits

  • CONA M 610 PN16: Grey cast iron EN-JL1040, up to 12.8 barg and 200 °C.
  • CONA M 610/612 PN40: Forged steel 1.0460 or stainless steel 1.4541, DN15–DN25, up to 22 barg and 385–400 °C depending on material.
  • CONA M 611/613 PN40: Higher capacity version with increased cross-section seat.
  • CONA M 616 PN40: Pilot operated / multi-capsule for very high condensate flow rates.

Thermostatic Capsules

Capsule selection determines discharge temperature:

  • No. 1: Near boiling temperature, up to 5 bar inlet pressure.
  • No. 2: Subcooling approximately 10 K, typical choice.
  • No. 3: Subcooling approximately 30 K.
  • No. 4: Subcooling approximately 40 K, mainly for low and medium pressure steam tracing.

Connections and Standards

Available with flanges EN 1092-1/-2, thread Rp per EN 10226-1, NPT per ANSI B1.20.1, socket weld per EN 12760, and butt weld prepared per EN ISO 9692. Documentation includes PED 2014/68/EU, AD 2000, TRD 201, and DIN 3230.

Applications

Suitable for steam tracing, small heat exchangers, heating lines, condensate collectors, and points requiring controlled subcooling before discharge. No actuator required. Selection based on pressure, temperature, condensate flow, desired subcooling, backpressure, and body material.

Maintenance

The CONA M can be installed in any position except cover/screwed cap downwards. Before startup, check material, pressure, temperature, and flow direction. Contaminants, welding residues, or clogged filters can cause leakage or reduced flow.

Datasheet and documents

Description

Key Features of CONA® M Thermostatic Steam Traps:

  • Thermostatic Steam Trap Design:
    • Suitable for discharging condensate from systems operating at various temperatures.
    • Automatic air-venting during start-up and operation.
    • Robust, water hammer-proof capsules for durability.
    • Non-return protection to avoid reverse flow (not available with controller R5).
    • Designed to handle sub-cooled condensate (with a range of temperature adjustments).
    • Inside or outside strainer options depending on model.


Types of Connections:

  • Flanges (DIN EN 1092-2)
  • Union with butt weld ends
  • Screwed sockets (Rp thread or NPT thread)
  • Socket weld ends
  • Compression ring connection (for PN40)
  • Clamp connection (for PN16)


Capsule Options:

  1. Capsule No. 1: For condensate discharge at boiling temperature (applicable up to 5 bar inlet pressure).
  2. Capsule No. 2: For condensate sub-cooling around 10K (Standard).
  3. Capsule No. 3: For condensate sub-cooling around 30K.
  4. Capsule No. 4: For condensate sub-cooling around 40K, especially for tracing systems with low and medium-pressure steam.


Models and Performance:

  • CONA®M 610 (PN16): Handles operating pressure up to 12.8 barg and inlet temperatures up to 200°C.
  • CONA®M 610/612 (PN40): Designed for higher pressures (up to 22 barg) and temperatures up to 385°C.
  • CONA®M 611/613 (PN40): A higher capacity version for steam traps requiring large flow rates.
  • CONA®M 616 (PN40): A high-capacity model with multi-capsules for very high flow rates, suitable for up to 32 barg pressure.


Material Options:

  • Grey Cast Iron (EN-JL1040)
  • Forged Steel (P250 GH)
  • Stainless Steel (1.4301, 1.4541)
  • High-Temperature Steel (16Mo3)


Applications:

These thermostatic steam traps are commonly used for:

  • Condensate discharge in industrial steam systems.
  • Steam tracing and heating applications.
  • Systems requiring high sensitivity and precise control over condensate drainage.
