Circulation Heaters

 

Our circulation heaters are packaged units consisting of a screwplug or flanged immersion heater mounted in a thermally insulated heating chamber for efficient heating of a flowing medium by in-line or side-arm operation. Thermocouple sensors can be provided to connect to most any controller. Select from many terminal enclosures, sheath and vessel materials, flanged connections, and controls. Many models in stock.Applications include: Water Heating, Freeze Protection, Heat Transfer Oil Heating, Fuel Oil Heating, Steam, Air, and Gas Heating and others.

Circulation Heaters – Clean Water Applications

Clean Water Heaters are ideal for heating municipal water for industrial washing and rinsing processes. Sturdy 0.475″ diameter copper sheath elements provide superior strength and rigidity. Chromalox elements utilize high quality resistance wire for coil construction. All stock and assembly stock heaters come with mechanical AR thermostats. These thermostats are suitable for most applications. Explosion-resistant and liquid-tight thermostats are provided on E2/E3 and E4 units, respectively. Other applications include indirect heating of viscous liquids and temperature maintenance of storage tanks.

Circulation – Fuel Oil Heaters

Light and Medium Weight Oil Heaters are ideal for temperature maintenance and for improving flow characteristics of oils. Fuel and gas heaters are also used for Heat Transfer Oils. Heavy or Fuel Oil Heaters will reduce the viscosity, thereby improving flow and process efficiency. Preheating fuel oils provides better automization at the burners and allows the use of lower grade fuel oils.

Application Guidelines

  • Screw Plug or Flanged Heater Design
  • 2 – 14″ Carbon Steel Pipe Body, 150Lb Construction
  • 1 – 200 kW
  • 120, 240 and 480V, 1 & 3 Phase
  • General Purpose, Moisture Resistant/Explosion Resistant, or Moisture Resistant Terminal Enclosure
  • 0.475″ Dia. Steel Sheath Elements (12 – 23 W/In2)
  • With & Without Thermostat
  • UL, CSA and Other Third Party Approval, Listing or Certification Available on Many Models

Circulation Heaters – Steam, Air, Gas

Chromalox circulation heaters provide a cost effective means for heating air and common industrial gases such as Argon, Helium and Nitrogen as well as gaseous mixtures for a wide variety of industrial processes. Incoloy elements and a Stainless steel vessel enhance safe operation to nearly 1400° F outlet gas temperature in air, gas, or steam superheating applications. They can also be used to increase the enthalpy and quality of steam. Smaller units can be used to make up line losses in steam generating and distribution systems.

Application Guidelines

  • Screw Plug or Flanged Heater Design
  • 2 – 18″ Carbon Steel Pipe Body, 150Lb Construction
  • 1 – 350 kW
  • 120, 240 and 480V, 1 & 3 Phase
  • General Purpose, Moisture Resistant/Explosion Resistant or Moisture Resistant Terminal Enclosure
  • 0.475″ Dia. Incoloy Sheath Elements (15 – 23 W/In2)
  • With & Without Thermostat
  • CSA and Other Third Party Approval, Listing or Certification Available on Many Models

Circulation Heaters – Corrosive Solutions and High Temperature Gas

Heat mildly corrosive solutions (pH5 to pH9) using stainless elements and a passivated stainless pipe body. Low watt density Incoloy sheath elements coupled with a passivated Stainless Steel pipe body provides long service life when heating highly corrosive solutions and sulfur laden oils. Incoloy elements and a Stainless Steel vessel enhance safe operation to nearly 1400° F outlet gas temperature in air, gas, or steam superheating applications. Fuel and Oil Heaters can be used in a variety of combustible solution applications.
