Electric Process Heaters

Tubular Heaters

Process Heaters
Used for immersion and air heating applications. They can be clamped to objects such as vessels and tanks, fitted into milled groove platens, immersed directly into a liquid being heated or even mounted in ducts for heating air and gas. Heaters are available as single- and double-ended, and can be formed to complex geometries.  Single- and double-ended tubular heaters lend themselves to virtually the entire range of immersion and air heating applications. They have a variety of mounting and termination options that make them ideal for industrial applications. Valax tubular heaters are UL® and CSA component recognized up to 240V.

  • Materials – Incoloy,  Inconel 600, Steel, Copper, 316SST, 304 SST
  • Maximum Temperature – 1800 F (982 C)

Immersion Heaters

These heaters can be immersed directly in the liquid being heated or put in protective wells. Multiple style mounting adapters are available.  Immersion heaters are designed primarily for direct immersion in liquids such as water, oils, solvents and process solutions, molten materials as well as air and gases. By generating all the heat within the liquid or process, these heaters are virtually 100 percent energy efficient. These versatile heaters can also be formed and shaped into various geometries for radiant heating and contact surface heating applications. UL® and CSA component recognized elements are available.

  • Products – Screw plug immersion, ANSI flange immersion, Over the side heaters
  • Materials – Incoloy, Stainless Steel, Copper, Titanium
  • Maximum Temperature – 1600 F (870 C)

Circulation Heaters

Diverse array of circulation heaters range from quartz heaters for aggressive chemicals to large pressure vessel heaters with capabilities up to 3000psi. These heaters can be used for liquids or gases in various applications.  Our circulation heaters are compact heating systems for fluids and gases. These heaters are ideal for applications such as purified and inert gases, supercritical fluids and liquids like de-ionized water for use in semiconductor and electronics industries as well as for general liquid and gas heating applications.Circulation Heaters

  • Materials – Incoloy, Quartz, Stainless Steel, Copper, Steel
  • Maximum Temperature – 1600 F (870 C)

Air Heaters

Air heaters can be used to prevent freezing and condensation in electrical and mechanical housing or can be placed in ducts for forced air heating.

  • Products – Duct Heaters, Finned Strip heaters, Cartridge Heaters, Enclosure Heaters
  • Materials – Incoloy, Aluminized Steel, Stainless Steel, Silicone Rubber
  • Maximum Temperature – 1400 F (760 C)

Cartridge / Insertion Process Heaters

Electric Process Heaters
Provide superior heat transfer, uniform temperatures, resistance to oxidation and corrosion and long life even at high temperatures.  Cartridge heaters and insertion heaters can be inserted into holes, used as immersion heaters placed directly in liquid or in protective wells, or can be mounted in pipes or vessels.

  • Materials – Incoloy, Stainless Steel, Alloy
  • Maximum Temperature – 2050 F (1120 C)

Strip / Clamp-on Heaters

Bolted or clamped to flat surfaces these heaters can provide freeze or moisture protection. These heaters can be attached to tank or vessel walls for warming.

  • Materials – Incoloy, 304 Stainless Steel, Aluminized Steel, 430 Stainless
  • Maximum Temperature – 1400 F (760 C)

Flexible Process Heaters

Band heaters for electric process heaters
Commonly used to heat irregular surfaces, shapes and pipes. These heaters can be bonded or fastened to parts and are often used for freeze protection.  Flexible heaters from Valax are thin, bendable and shaped to fit almost any equipment. Heat can be applied to the most complex shapes, geometries, curves and pipes conceivable without sacrificing efficiency or dependability.

  • Materials – Silicone Rubber and Polyimide
  • Maximum Temperature – 500 F (260 C )

Band / Barrel Process Heaters

The mineral insulated band heater is a high-performance heater.  A thin layer of the “high” thermal conductive MI material is used to electrically insulate the element wire from the inside diameter of the heater sheath. A thicker, “low” thermal conductivity layer backs up the element wire directing the heat inward toward the part being heated. The result is more efficient heat transfer, which lowers element wire temperatures and increases heater life.

Nozzle Process Heaters

These heaters are formed to fit cylindrical parts. Applications for these heaters range from industrial processes to medical applications.

  • Products – Mineral Insulated Nozzle Heaters, Thick Film Cylindrical Heaters, Pre-coiled Nozzle Heaters
  • Materials – Stainless Steel
  • Maximum Temperature – 1400 F (760 C)

Radiant Process Heaters

Used in non-contact applications where conduction or convection heating is not practical.

  • Products – Band and Strip Emitters and Panel Heaters
  • Materials – Stainless Steel
  • Maximum Temperature – 2000 F (1095 C)

High Temperature Heaters

High Temperature Heaters
These high-temperature heaters are used for extreme high temperature applications. The heaters fit applications such as the construction of furnaces and chambers.  We can supply products in various sizes and constructions to fit a broad range of processes and applications. The tubular and ceramic fiber heaters offer capabilities such as ultra-fast ramp rates, precise temperature uniformity and high temperatures for applications requiring low thermal mass. Heaters are sized and designed to accommodate small to large applications and various environmental conditions

  • Materials – Incoloy, Inconel 600, Ceramic Fiber
  • Maximum Temperature – 2200 F (1204 C)

Thermostats and Accessories

We can provide a variety of thermostats and accessories that can be integrated with the heaters. By providing a one-stop solution customers do not have to use multiple component suppliers.
