Large-Tank Heaters

Chromalox large tank heaters provide cost-efficient heating of stored viscous materials by precisely sequencing operation to take advantage of off-peak electricity rates. They require very little upkeep and maintenance. That helps reduce both labor cost and the time and material costs of inefficient heating. Chromalox offers a number of large tank heater solutions to meet the needs of petrochemical plants. Click here to visit catalog



Designed for use with organic fluids to transfer heat at high temperatures and low pressures, Chromalox pre-engineered, prewired, and pre-piped packages are designed for flexible, dependable, and efficient operation. All units are ASME-certified to 150 psi at 750 °F (400 °C) with 300 lb construction throughout. Seal-welded element design eliminates leaks and improves serviceability. Available with over-pressure, process, remote, or skid-mounted controls. Click here to visit catalog


Immersion Heaters

Chromalox immersion heaters apply heat directly at virtually 100 percent efficiency. Basic piping options include threaded, flanged, or welded. Various temperature control options permit very tight process temperature control. Our circulation heaters are designed to heat a flowing medium using in-line or side-arm piping configurations. A wide selection of kilowatt ratings, materials, vessel sizes, terminal enclosures, control features, and mounting methods is available. Click here to visit catalog


Circulation Heaters

Our circulation heaters are designed to heat a flowing medium using in-line or side-arm piping configurations. A wide selection of kilowatt ratings, materials, vessel sizes, terminal enclosures, control features, and mounting methods are available. INCOLOY® sheathed elements, stainless steel vessels, and high-pressure ASME ratings enhance safety and the service life of turbines. Click here to visit catalog


Hazardous Duty Convection & Blower Type Heaters

Hazardous-duty convection and forced air blower-type heaters are designed for rugged industrial use in the presence of potentially flammable or explosive gases, vapors, or dusts in locations such as sewage treatment plants, petroleum refineries, and chemical processing plants. Numerous control options are available. Units are UL-listed, and GSA- and MSHA certified models are available for wall or ceiling mounting. Consult the National Electric Code for classification of your hazardous area before selecting your heater. Click here to visit catalog



Chromalox prewired, skid-mounted circulation heat systems provide high performance for the burning, reduction gas, and calcination gas heaters inside catalyst regeneration units. Flanged immersion elements provide superior strength and rigidity, and can be easily removed for cleaning and inspection. Heater vessels come in an array of sizes and meet virtually any kilowatt or corrsion resistance requirement. And their metal skid mounts, with vessel and control panel securely attached to the frame supports, enable easy handling. Click here to visit catalog


Heat Trace & Controls

Heat trace is used to counteract the heat loss from process equipment and piping through its insulation, to prevent solution precipitation and the increase of viscosity or solidification of product, and to provide freeze protection. Chromalox offers a variety of heat trace cable; temperature control, monitoring, and management in one, modular package; and all of the necessary components needed to complete the installation, including splices, power connection boxes, and water-resistant end-seal terminations.
