8' Complete Assembled for Panel-Trim Baseboard, 300 BTU

Argo Panel-Trim II Hydronic Baseboard, 8-Foot Assembly – Model 55PT2CU75-8

The Argo 55PT2CU75-8 is an 8-foot hydronic baseboard enclosure system with integrated high-output copper/aluminum fin-tube element. Designed for use in both commercial and residential heating systems, the Panel-Trim II line delivers effective heat transfer in low-profile applications where wall space is constrained and heat demand is elevated.

System Configuration

This factory-assembled panel includes a pre-painted, 18-gauge cold-rolled steel cover, finned-tube element with 3/4" copper pipe and aluminum fins, built-in damper for airflow control, plastic glide hangers to minimize operational noise, and end-to-end alignment features. Designed to simplify field installation while maintaining high thermal performance.

Key Specifications

• Length: 8 feet (nominal)
• Tubing: 3/4” copper (Type L)
• Fin Material: Mechanically bonded aluminum
• Enclosure: 18-gauge cold-rolled steel, white pre-painted finish
• Output: Approx. 300 BTU per linear foot (water temperature and flow dependent)
• Mounting: Wall-mounted, with snap-on cover for maintenance access

Performance Features

• Thermodynamic Damper: Integral damper enhances convective air movement and enables manual adjustment of heat output.
• Corrugated Element Design: Maximizes fin surface area and improves air flow for uniform room heating.
• Noise Reduction: Plastic cradle supports prevent metal-on-metal expansion sounds during operation.
• Interchangeable Design: Compatible with other Panel-Trim II series components for scalable system design.

Installation Guidelines

Installation should be performed by a licensed HVAC or plumbing contractor to ensure compliance with applicable building codes and system specifications. Units must be properly supported at specified intervals to prevent deflection. Tubing joints require soldering or approved mechanical fittings. System balancing and flow rates should be confirmed after installation to ensure design performance.

Use Cases

• Perimeter heating in high-demand zones such as entryways, curtain walls, or open-plan rooms
• Retrofitting in commercial or multifamily projects with limited mounting space
• Integration with closed-loop, hot water-based hydronic heating systems
