Standard Construction Features

• ANSI B16.5 150# or 300# flange 2″ up to 36″
• Designed to fit into schedule 40 or schedule STD pipe for the given flange size
• Flange material A105 carbon stl, A182 304/304L or 316/316L stainless steel
• Elements sheath materials available; steel, 304 SST, 316 SST, 321 SST, incoloy 800, incoloy 840, copper
• Epoxy or RTV sealed heating elements to prevent moisture absorption
• Stainless steel welded bussing to eliminate loose connections
• Heater circuits divided into 48A max as default
• Heavy duty, low pressure drop design, 304 SST element support spacers provided on 24″ centers
• Spacer support rods provided on 10″ and larger flange sizes
• General purpose, weather proof, or explosion-proof terminal enclosure
• Lifting lugs for heaters 4″ and larger
• Nitrile bonded fiber, or SST/graphite spiral flange gasket provided as standard
• Certifications – cCSAus certified and UL Recognized for general purpose and weatherproof constructions. (per CSA 22.2 no. 72 and 88 / UL574 for Oil / UL1030 or UL499 for water or air)

Optional Features

• Extended terminal box
  Provided when the heater is operating above 500° F to allow for cooler operation of the terminal box. This allows the heating elements to be sealed with epoxy or RTV and for the customer to provide incoming wire with a much lower insulation temperature rating.
• ASME
  The heater can be supplied in accordance with ASME section VIII Div. 1 U-Part stamped and certified.
• Thermostats
  Bulb and capillary pilot duty or load carrying thermostats can be provided to control the heater or to provide over-temperature protection. The thermostat bulb can be installed in a thermowell to sense process or element sheath temperature.
• Thermocouples
  Type J or K thermocouples can be provided to monitor the process or element sheath temperatures. Thermocouples provided with a ceramic wafer head and screw terminals for ease of wiring. Alternate type E or T available but not FastTrack eligible.
• Hermetically sealed element terminations
  A ceramic to metal soldered seal can be provided to eliminate the possibility of moisture from entering the heating element.
• Removable bussing
  Allows troubleshooting and isolation of a failed heating element.
• Cross-baffle
  Construction utilizes alternating half baffles spaced closely to cause increased flow velocity across the heating elements to allow better heat transfer from the elements to the fluid.
• Ventilated general purpose cover
  Provides means for heat to exhaust from the terminal box to minimize heat buildup.
• Add support rods for flange sizes 8” and smaller
  Support rods can be added to high flow heaters to keep the element support spacers in place.
• Larger heater circuits for greater than 48A per circuit
• Heavy wall pipe design
  Element bundles with smaller outside diameter can be provided for any flange size requested.
• Pickle and Passivate
  A chemical treatment in nitric acid can be performed to remove free iron from the outer surface of stainless steel for applications sensitive to contaminants.
• Electro-polish
  Is a process similar to plating using cathode and anode reactions but material is removed rather than added to the heater surfaces in order to provide a clean and bright finish.
• Ring and cover weatherproof or corrosion resistant enclosures
  Heavy duty pipe and plate construction.
• Other element sheath and flange materials available
• Flange ratings greater than 300# are available up to 2500#
