Item # HX-234-U11N-0090C, 234 Series Washdown/Corrosion Resistant Unit Heater

The Heatrex 234 Series unit heater is the perfect solution to the problem of heating people or equipment in non-hazardous environments where moisture and corrosion exist. Advantages include :
  • Built-in Controls : All necessary safety and temperature controls are included in a single package. Components and motor are factory-wired to a single terminal block for field wiring, eliminating the chance for field error and reducing installation costs.
  • Single Point Electrical Hook-up : Heater, fan motor and controls are all connected to the same branch circuit.
  • Corrosion Resistant : Stainless steel construction, epoxy-coated aluminum fan blade and nonmetallic NEMA 4X terminal enclosure resist corrosion found in sewage treatment plants, swimming pools, car washes, paper mills and marine installations.
  • Washable : This watertight construction can be hosed down without disconnecting the heater, which makes it ideal for coal handling areas, steel mills, foundries, ships, wood finishing plants, cement, sand, grain and food processing facilities.
