4' Hydronic Assembled Enclosure for Panel-Trim Baseboard

Argo Panel-Trim II Hydronic Baseboard Enclosure – 4-Foot Section (Model 55PT2CO-4)

The Argo Panel-Trim II is a commercial-grade baseboard enclosure designed to house high-output hydronic fin tube heating elements. This 4-foot section is constructed from pre-painted 18-gauge cold-rolled steel and is part of Argo’s heavy-duty enclosure system for perimeter hot water heating applications. Its low-profile design and high capacity make it suitable for areas with limited wall space and elevated heat loss requirements.

Product Overview

Panel-Trim II enclosures are engineered for use in both new construction and retrofit projects, offering quick access via snap-on covers and compatibility with a full range of trim and end-cap accessories. The enclosure accommodates standard 3/4" copper fin tube heating elements and is intended for use in baseboard hydronic systems operating at conventional temperatures and pressures.

Installation Considerations

The Panel-Trim II enclosure is field-assembled and should be installed by a licensed plumbing or HVAC professional. The fin tube element must be properly supported using manufacturer-approved mounting brackets to maintain alignment and allow for thermal expansion. Air inlet and outlet clearance should be maintained per system design requirements. Covers are removable for periodic maintenance or cleaning.

Performance Notes

When used with a properly sized fin tube element, the Panel-Trim II enclosure contributes to high-output perimeter heating performance. Ensure system flow rates, supply temperatures, and control strategies are appropriate for the zone requirements. This product is not rated for use in steam systems.
