Armstrong Chemtec brings over 75 years of process heat transfer experience to electric heater design. Armstrong Chemtec will work with you to determine the best electric heater for your application. In addition to meeting all thermal and hydraulic constraints, Armstrong Chemtec electric heater design also considers process conditions and fluid behavior.

Immersion Heaters

Fluid properties, fouling, heat transfer rate, etc. complicate the normally straightforward process of electric heating. Armstrong Chemtec brings over 75 years of process heat transfer experience to electric immersion heater design. This robust design optimizes performance and element life in high heat transfer rate applications. Finned elements may be used for viscous fluids to enhance heat transfer.

Features Include:

Significant standoff between the terminal box and tubesheet, allowing for low temperature wiring in the terminal box and preventing process leakage into the terminal box
Thermocouples welded to element sheaths, assuring accurate element temperature monitoring
Element moisture seal, offering protection against equipment failure and startup delays

TIG tubesheet joints preventing process fluid leakage
Large terminal box, providing easy access for installation and maintenance
Duplex thermocouples (optional), allowing for redundancy or spares provision

Radiant Heaters and Furnaces

Armstrong Chemtec fluidized bed radiant heaters heat and maintain temperature for fluidized bed reactors. These low maintenance heaters are supplied in three 120º sections, and encapsulate the entire section of the reactor that requires temperature control. Armstrong Chemtec fluidized be radiant heaters have been used most frequently in catalyst regeneration, activation, dehydration, and polysilicon manufacturing.

Features

Internally insulated shell casing with 200 to 300 mm of modular ceramic fiber
Ability to accommodate large diameter pressure vessels and heat them to 1090 ºC (2000 ºF)
Indirect Heat Transfer
Accessible, replaceable radiant heating elements secured to the inside wall of the insulation

Impedance Heaters

Armstrong Chemtec impedance heaters marry electrical, heat transfer, and mechanical engineering concepts into a robust electric heater for difficult duties. By using the pressure containment vessel as the electric heating element, numerous thermal resistances are removed, allowing these heaters to reach higher temperatures than immersion heaters.

Armstrong Chemtec impedance heaters range in size from 10 kW to over 1 MW. These heaters have been used in a wide variety of difficult process applications, such as:

Heating supercritical fluids, including water, ammonia and carbon dioxide
Heating gases to temperatures above 1010 °C (1850 °F)
Tubular reactors requiring heat input
Heating fluids at pressures in excess of 240 bar(g) (3500 psig)
