Flanged Open Coil Duct Heater Brasch Open Coil Flanged Electric Duct Heater

Brasch Open Coil Electric Duct Heaters are custom engineered to customer specification and built to order.  They are available UL listed in Slip-in or flanged configurations with heavy gauge galvanized steel frame and terminal box construction.  Units include primary and secondary thermal protection and are designed for use with vertical up or horizontal airflow in either direction.  Alternate constructions are available for oven heaters, round duct, bottom insert and raintight installations.  Elements are constructed using only the highest A-grade 80/20 nickel-chromium resistance wire with stainless steel terminals.  Other optional construction features include recessed, dust tight or insulated terminal box, insulated flanges and protective screens.

A wide assortment of built-in control options are available.  Exact, not typical, wiring diagrams are provided with each heater.   Super-X heaters, a subset of sizes with more limited control options, have standard two week delivery, but premium shipment of custom open coil electric heaters can be accomplished in as few as two working days.
