Heatrex's Compact explosion-proof unit heater is designed with both size and economy in mind. 236 Series advantages and unique features include :
  • Compact Size : This small design is only 13 inches wide, which makes it ideal for applications where limited space is available.
  • Low Cost : The Compact design offers the most economical solution for heating small Class I, Group D hazardous areas. It is a cost effective alternative to the use of explosion-proof convection heaters.
  • Redundant Over temperature Protection : Primary and secondary automatic reset thermal cutouts for additional safety.
  • Stainless Steel Construction : Provides superior corrosion resistant protection. Optional Dirty Duty construction adds epoxy coating to all aluminum parts for use in corrosive applications.
  • Optional Marine Duty Construction : The 236 Series design is ideal for shipboard use where size, weight and corrosion resistant construction are critical.

Standard Construction Features
  • Heating Elements - Industrial grade, Type 304 stainless steel finned tubular heating elements.
  • Terminal Enclosure - A NEMA 7, 9 cast aluminum enclosure with a threaded bottom cover permits easy access to the built-in controls from underneath the heater.
  • Housing - Round, 16-gauge stainless steel shroud.
  • Grilles - An adjustable stainless steel louvered outlet grille directs airflow 45° up or down and a heavy gauge zinc-plated rear grille protects against accidental contact with the fan blade.
  • Stainless Steel Swivel Mounting Bracket - Supplied as standard with all 236 Series compact explosion-proof unit heaters. This multi-purpose bracket can be used for either wall or ceiling mounting.
  • Built-In Controls - Include primary and secondary automatic reset over temperature cutouts, controlling and backup contactors (as required), and a time delay relay which keeps the fan running to cool the heating elements after they have been de-energized.
  • Fan Motor Assembly - Consists of a 120-volt/1-phase/ 60 Hertz motor fitted with an aluminum fan blade. The totally enclosed motor is UL Listed for Class I, Group D applications and includes permanently lubricated ball bearings and built-in thermal overload protection. The motor is factory wired into the enclosure to reduce field wiring, but requires a separate 120-volt power supply.
