TUTCO DUCT
E-Series Flip-Able Duct Heaters
Fast, Flexible, Superior Electric Duct Heaters
TUTCO E-Series Flip-Able Electric Duct Heaters combine flexible installation, reliable heating performance, and a wide range of configuration options for commercial HVAC applications. Designed with a symmetrical, left-right neutral construction, E-Series heaters can be installed in four different orientations, eliminating the need for separate left- and right-hand designs. These open-coil electric duct heaters are engineered for efficient heat transfer and minimal airflow restriction. Available in multiple voltages, kilowatt ratings, and control configurations, E-Series heaters can be specified for primary heating, supplemental heating, reheating, and multi-zone HVAC systems. With UL 1996 and ETL certification, customizable designs, and fast manufacturing lead times, TUTCO E-Series heaters offer a versatile solution for both new installations and HVAC system upgrades.

Whether specifying heaters for a new HVAC installation, replacing existing equipment, or integrating electric heating into an OEM system, TUTCO provides the product flexibility and support to meet project requirements.
Applications
TUTCO E-Series heaters are designed for commercial HVAC systems requiring flexible electric heating configurations, including:
- Single-duct VAV terminal unit reheat
- Multi-zone commercial HVAC systems
- Supplemental and auxiliary heating
- Primary electric duct heating
- Space heating and temperature control
- Air reheating and recirculation
Designed for Installation Flexibility
The E-Series heater's Flip-Able design simplifies specification, ordering, and installation. Its symmetrical construction allows a single heater configuration to accommodate four mounting positions, reducing the need for multiple heater designs. This flexibility is particularly valuable in commercial HVAC installations where duct orientation, available space, and terminal placement can vary.
Key design advantages include:
- Four mounting positions: One heater can be rotated to accommodate different installation requirements.
- Symmetrical construction: Eliminates the need for separate left- and right-hand heater configurations.
- Simplified specification: One heater design accommodates multiple installation requirements.
- Flexible mounting options: Available in slip-in, flanged, and custom configurations.
- Reduced installation complexity: Helps minimize field modifications and installation delays.
Engineered for Reliable Electric Heating
TUTCO E-Series Electric Duct Heaters utilize open-coil resistance heating elements designed to transfer heat directly to the air moving through the duct system. The open-coil design provides effective heat transfer while maintaining low resistance to airflow. The heaters are available with 80/20 nickel-chromium resistance wire, stainless steel terminals, and optional derated coils to accommodate specific performance and operating requirements. A wide range of electrical configurations and custom staging options allows E-Series heaters to be matched to the heating capacity, airflow, and control requirements of the HVAC system.

Why Customers Choose TUTCO Over Indeeco, Thermolec, Tempco, and Brasch
Competitors offer open-coil duct heaters, but lead times are longer, installation flexibility is limited, and customization often adds complexity and cost.
- Indeeco – strong in custom duct heaters, but turnaround times typically run longer than TUTCO’s 24-hour expedited builds.
- Thermolec – offers open coil designs, but lacks the flip-able, left-right neutral versatility of the E-Series.
- Tempco – catalog duct heaters cover many applications, but don’t match TUTCO’s online instant quoting and next-day ship options.
- Wattco – provides broad heater categories, but struggles with the engineering collaboration and application support that TUTCO delivers.
- Brasch – widely known for standard open-coil units, but their manufacturing speed cannot compete with TUTCO’s 1-2 day rush manufacturing.

Frequently Asked Questions
Proper duct heater selection typically begins with the duct dimensions, airflow, entering and desired leaving air temperatures, supply voltage, phase, and available electrical power. These factors determine the heater capacity and configuration required to achieve the desired temperature rise while maintaining proper airflow across the heating elements.
Yes. E-Series duct heaters can be configured around the electrical, airflow, dimensional, and control requirements of the application. Options include slip-in, flanged, and custom designs, along with custom staging, disconnecting contactors, recessed control boxes, vapor barriers, gasketed covers, stainless steel construction, and other features.
TUTCO E-Series duct heaters are available in standard supply voltages from 120V to 600V and can be configured for single-phase or three-phase power. A standard 24V control voltage is available, and staging can be customized to meet the requirements of the HVAC system.
The E-Series features a symmetrical, left-right neutral design that provides greater flexibility during installation. Unlike conventional duct heaters that may require a specific orientation, E-Series heaters can be installed in multiple orientations without redesigning the heater or making field modifications.
TUTCO E-Series duct heaters are open-coil electric heaters designed for installation in HVAC ductwork to heat air as it moves through the system. They can be used for primary heating, supplemental heating, space heating, reheating, recirculating air, and multi-zone HVAC applications.
