SoHo Hydronic Trench Heaters

 

SoHo-w Hydronic Fan-Powered Linear Terminal is designed to create an efficient and simple solution to meet perimeter heating needs, in a variety of residential and commercial applications. The unit is ETL listed, fully certified to UL standards.

The low profile terminal housing is 20 gauge (1mm) galvanized steel, pre-painted black. It is designed primarily for low-height raised access floor and recessed perimeter trench installation. Multiple mounting options are available; the terminal can be suspended from adjacent finish floor surface via support flanges, or it can be set directly on a floor (or subfloor) on threaded leveling legs, which provide up to 1" (25mm) of manual height adjustment.

The hydronic fin pack has been rated in accordance with AHRI Standard 410; rows are 3/8"Ø (9.5mm) copper tubing with standard 1/2" Male NPT (15mm) supply and return connections. Finned length and heating capacity are dependant on overall terminal length and scheduled performance requirements (specify on order).

Heat is actively circulated using air flow supplied by 24VDC variable speed ECM cross-flow fans; configuration and maximum capacity is dependant on overall length of the terminal / fin pack. Primary power and controls are housed externally in a SoHo Hub control box (available separately); signals are transmitted via plug and play molex connection. The linear grille is available as extruded aluminum or stainless steel, in a variety of sizes and configurations (specify on order).

SoHo-w/c Hydronic Fan-Powered Linear Terminal is designed to create an efficient and simple solution to meet perimeter heating and cooling needs, in a variety of residential and commercial applications.

The low profile terminal housing is 20 gauge (1mm) galvanized steel, pre-painted black. It is designed primarily for low-height raised access floor and recessed perimeter trench installation. Multiple mounting options are available; the terminal can be suspended from adjacent finish floor surface via support flanges, or it can be set directly on a floor (or subfloor) on threaded adjustable leveling legs, which provide up to 1" (25mm) of height adjustment.

The hydronic fin pack has been rated in accordance with AHRI Standard 410; rows are 3/8" (9.5mm) copper tubing with 1/2" NPT (15mm) supply and return connections. Finned length varies based on overall terminal length and scheduled performance requirements (specify on order). Hot or chilled water can be passed through to meet seasonal heating and cooling requirements.

An IEQ double deflection drain pan extends under the entire length of the water coil / connections. The drain pan is galvanized steel, pre-painted black, and includes a 3/4" (19mm) condensate drainage connection. The terminal interior (including the drain pan) is fully lined with insulation to prevent undesirable condensate formation.

Active air flow is provided by 24VDC variable speed ECM cross-flow fans, available in standard and high capacity configurations to meet a range of performance requirements. Primary power and controls are housed externally in a separate SoHo Hub control box; signals are transmitted via plug & play molex connection.

The linear grille is available as extruded aluminum or stainless steel, in a variety of sizes and configurations. Ten (10) standard colors are available; custom colors and finishes can be provided to match architectural design (specify on order).

I’m always worried about trying something radically different in our projects. What if it doesn’t go to plan? What if there’s something we haven’t considered? Those concerns were completely unfounded with UFAD. it was far less complex, and way easier to plan and install than a traditional system.
