Series WF Welded Frame Air Handling Units:

For nearly 50 years, the Temtrol tradition has featured rugged, industrial welded-frame construction. Our Series WF units can be custom designed in a virtually unlimited range of sizes and configurations...a consulting engineer's delight when the requirements are for tough, custom applications.

Key Benefits:

Any size, any configuration (adhering to shipping limitations and good engineering practices)
Fans picked at the "peak of the curve"
Special vendor items designed into the unit and factory mounted

Construction Features:

Completely mig-welded tubular steel frame and base
Single or double wall casing construction with any popular panel insulation fill or thickness.
Solid or perforated inner liners with galvanized steel, stainless steel or aluminum.
True "double bottom" floor construction with four inch thick insulation fill. Full walk-on interior surfaces of G-90 galvanized steel or aluminum tread plate.
Double-die formed 16 gauge G-90 galvanized exterior panels installed with closed cell neoprene gasket around the entire periphery, and 1/4" gasket fasteners for air-tight performance. All panels are completely removable without affecting structural integrity of unit.
Thermal break construction between exterior panel and frame ensures an air-tight fit, and guarantees "no through metal" construction.
Internally spring-isolated structural steel fan bases with housed airfoil, plug, forward curved or axial fans at your choice through Class III construction.
Indoor or outdoor curb-mounted construction complete with internal pipe chases or external vestibules.
Full line of 1/2, 5/8, or 1-1/8" O.D. tube, ARI-certified coils.

Design Flexibility

Each unit is custom-tailored to fit your application with fans picked at the "peak of the curve."
Each component is maximized to best utilize cabinet space, ensuring peak performance and lowest first cost.
Any size or any configuration (within shipping limitations and good engineering practices) is available.
Units available in right angles or stacked arrangements to conserve equipment room space.
Special vendor items such as IFB coils, humidifiers, blenders or evaporative coolers can be designed into the unit and factory mounted.
Multiple fan arrangements can be used for redundant operation or low profile cabinets.
