The out-of-sight, out-of-mind UL listed in-floor perimeter trench heater.
THX drops into the floor, directly addressing the building's need for supplemental heat against the curtain walls and glazing, in new or remodeled spaces—without compromizing the building's design aesthetic.
THX creates an effective draft barrier, preventing condensation on exterior windows and curtain walls and preserving the primary HVAC system from inefficiency and higher utility costs.
Avoid the time and expense of certifying on site. THX is designed with water and debris management in mind. It features a sealed junction box and raised connections points, plus a wire screen beneath the grille catches debris to prevent it from entering the unit.
Get maximum heat output—30% more watts per cu. ft. than the competition1—with the most compact unit in its class2.

THX units come in 2 to 5 foot modular lengths, are factory wired and preassembled for out-of-the-box readiness, drop-in installation, and easy access for cleaning and maintenance, with one service professional.
THX warms air at the base of exterior windows, creating a natural updraft that protects your building’s heat envelope and curtain walls. Windows stay free of fog and condensation and warm air circulates throughout the space with no need for a fan or blower.
