Direct Expansion (DX) Air Handler
& "A" Coil

R410A, Multi-Position

1.5 - 6


Enertech’s Direct Expansion (DX) Air Handler (EAD) exceeds Energy Star’s efficiency requirements, making it the perfect choice for those wanting reduced operating costs. Its internal ECM fan motor is 33 percent more efficient than standard PSC motors, all while maintaining consistent, quiet operation.


The components of Enertech's DX air handler are wrapped in a sturdy cabinet, consisting of 18-gauge, galvanized steel that virtually eliminates harmful flex and excessive vibration during normal operation. This air handler is built to last.


The small footprint afforded by the all-aluminum microchannel “A” coil allows the EAD to do more for your home while taking up less space. While most residential air handlers are only sized up to 5-ton capacities, the EAD comes in an up-to 6-ton model. Plus, with up-flow, down-flow, and horizontal-flow configurations, this product is a multi-positional powerhouse.

1 Variable-Speed ECM Fan Motor

This high-efficiency, low-maintenance fan motor provides top-tier speed control to accommodate the smallest changes in system load. This variable speed motor allows for a remarkably consistent CFM across a wide range of spaces.

2 Closed Cell Cabinet Insulation

Traditional cabinets use a spray-in fiberglass cabinet insulation, which can lead to dust and sediment being distributed in the air throughout the home. Our EAD is insulated with a closed-cell foam, providing superior sound dampening and improved indoor air quality.

3 Removable, Robust Cabinet Doors

Enertech's DX air handler has unmatched flexibility and strength. Like Enertech-built geothermal systems, the robust cabinet, made with 18-gauge galvanized steel, manufactured in Mitchell, SD, has removable cabinet doors for ease of access.

4 All-Aluminum Microchannel Air Coil

The DX is the only air handler in the US geothermal market that comes with an all-aluminum microchannel air coil. This component boosts performance by 20-40 percent, requires less refrigerant, and is more corrosion resistant than traditional “tube and fin” air coils.


Compatible Units

Enertech Indoor Split BS/BT


Enertech’s Indoor Split (BS/BT) heat pumps provide ducted heating and cooling and hot water assist for 25% - 40% savings on hot water costs annually. These systems can be paired with a conventional furnace to create a dual-fuel system with optimal energy savings. The BS/BT heat pumps can be used for heating and cooling in small to large homes, storage buildings, agricultural facilities, and more.
Enertech Outdoor Split RT


The Enertech RT outdoor split heat pumps can provide forced air heating and cooling, hot water assists for 25% - 40% savings on hot water costs annually, or can be used with a conventional furnace to create a dual-fuel system for optimal energy savings. The RT models are similar to the BS/BT indoor split systems, except the RT is installed outside, making these systems perfect for applications where there isn't space for a unit indoors, like in small homes or buildings.
