ARI CONA TD – Thermodynamic Steam Trap

The ARI CONA TD is a thermodynamic steam trap designed for discharging lightly to heavily subcooled condensate in steam networks. It operates periodically via a disc/controller and does not require an external actuator. The series includes a body with an internal filter Fig. 640 or an external filter Fig. 641 Y.

Technical Specifications

• Versions PN40 and PN63.
• DN15–DN25 for PN40 / PN63, and DN10–DN25 in the stainless steel PN63 version.
• Materials: 1.0460, 1.5415, 1.4541, A743 CA40 / 1.4006.
• Permissible differential pressure: up to 32 bar for PN40 and up to 42 bar for PN63, depending on the version.
• Minimum operating pressure: 0.7 barg or 1 barg, depending on type.
• Backpressure to inlet pressure ratio: ≤ 0.8.

Connections

Available with flanges EN 1092-1, thread Rp according to EN 10226-1, NPT according to ANSI B1.20.1, socket weld according to EN 12760, and butt weld prepared according to EN ISO 9692.

Application Selection

The CONA TD is primarily used in:

• steam line drainage,
• steam tracing,
• superheated steam,
• areas with potential water hammer,
• outdoor installations where the thermal protection chamber reduces the impact of wind, rain, and low temperatures.

For heat exchangers with continuous and high condensate flow, the selection of a float steam trap should be considered separately.

Maintenance

The controller is replaceable. The screwed cover does not use a gasket, while the filter protects the seat from particles. In new networks, pipe cleaning is required before startup.

FAQ

Can it be installed in any position?
Yes, the technical datasheet indicates installation in any position.

When is it not the first choice?
When condensate backing-up is not allowed or when the process requires continuous drainage without periodic operation.
