High-capacity architectural convection heater that delivers quiet, fan-free heat for large commercial spaces.
The King KLA Series architectural convection heater provides up to 6,000 watts of silent, fan-free heat for large commercial and institutional spaces. Its natural-convection design is well suited for hospitals, daycare centers and other applications where quiet operation is important.
Stainless steel tubular heating elements with aluminum fins provide durable heat output, while floating element supports help minimize expansion noise. Standard units use a front air inlet and top warm-air outlet; models with the optional front outlet (-FR) may be fully recessed.
Not approved for residential use in the United States. Wall-to-wall accessories, pedestals, sub-bases, empty cabinets and clean-back configurations are available.
