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.
Flanged Immersion Heaters
Flanged immersion heaters provide virtually 100 percent energy efficiency for the
heating of large oil tanks. Their bayonet styling provides high watt densities, and
available temperature control options permit extremely tight process temperature
tolerances. A wide range of standard designs is available for immediate delivery, or
Chromalox can design a custom solution for you.
Flexible Tank Heaters
Chromalox flexible tank heaters are ideal for underground tanks or units without side
entry. They spread heat evenly in tanks made from steel, concrete, or Fiberglas®,
preventing hot spots and carbonization. In addition, they install through normal manhole
openings, so no modification is required. They also allow for tank system operation with
little or no manual attention, and using them enables maintenance work to be done
without draining the tanks.
Unitary Large Tank Heaters
Chromalox unitary large tank heaters offer low watt density heating over large heated
surfaces with precise temperature control. They are self-contained, can be maintained
with little or no manual attention, and eliminate the need to drain tanks. Designed for
work under tight space constraints, some models require only three feet of space for
installation or removal. And local control panels, complete with weatherproof
enclosures, help prevent overtemperature operation and damage from power surges.
Chromalox circulation heaters afford high energy efficiency, fast heating, and
uniform heat distribution for numerous petrochemical plants heating applications such as
H2-rich and Claus gas heating, desulphurization, and air and flue-gas heating. They also
provide high turndown capability, tight outlet temperature control, and variable flow
rates. And Chromalox offers a variety of electrical terminal enclosures to meet the
unique requirements of petrochemical facilities.
Chromalox circulation heaters also superheat steam, either for higher process
temperatures or to clean the steam itself. Our smaller units also help make up line
losses during transportation from central steam generation systems. High watt densities
and operating temperatures are obtainable with Chromalox steam superheaters, thanks to
the high quality of their INCOLOY® flanges and ASME-certified, carbon steel
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
any kilowatt or corrsion resistance requirement. And their metal skid mounts, with
vessel and control panel securely attached to the frame supports, enable easy
Heat Trace and Controls
Heat tracing helps avoid process temperature drops that can lead to freeze-ups in
plant areas like cooling towers, instrumentation lines, process water, safety showers,
fire protection piping, and condensate piping. Providing temperature stability helps
prevent unacceptable viscosity increases and solidification of fluids in the lines.
Self-Regulating Heat Trace Cable and Controls
Chromalox self-regulating heat trace and control systems can save energy, reduce
maintenance, and the risk of overtemperature. The cable can be single-overlapped without
burnout, cut to length in the field, and easily spliced. Outperforms industry
competitors in field life, insulation integrity, and resistance against increasing
Constant Wattage Cable
Provides accurate temperature and reliable heat to 300ºF. Heating output is uniform
through its entire length thanks to its parallel heating core. Flexible and rugged.
Withstands steam cleaning to 190 psi at 392ºF when de-energized. Can be cut to length in
the field, making installation easier.
Mineral Insulated Cable
Ideal for the most rugged pipe tracing applications, up to 1,200ºF. Fire-resistant
and does not support combustion. Provides reliable electrical ground for safe operation.
Custom configurations available with single or dual conductor cable.
A complete control solution for heat trace applications with a modular design for
selection of only the features needed for specific heat trace installations, minimizing
the purchase price and simplifying system configuration. Single-channel system using
microprocessor-based control. Comes completely pre-wired and assembled. Easily
programmed standard features further simplifies installation, start-up, and use. All
IntelliTRACE systems are designed for universal inputs. Each unit comes in a NEMA 4X
glass fiber reinforced enclosure that includes a solidstate relay (30A at 40°C), mounted
on a heatsink, and with a current transformer to measure operating current. Optional GFI
modules have a shutdown contactor and illuminated reset switch. A terminal block is used
for field connections on all units.
Custom Power Control Panels
Panels engineered with solid-state controls built to the most rigid standards
and sized for virtually any application or specification. Select from many NEMAtype
enclosures, single- or three-phase load requirements, voltages, transformers, fusing,
contactors, firing cards, and more. We can design the power contro panel best-suited for
your specific application.
Auxiliary Electric Steam Boilers
Chromalox auxiliary steam boilers can be placed anywhere steam is required and
electricity is available. They are ideal for remote locations where plant steam is not
economical, providing hot water or steam on demand for emergency or maintenance downtime
backup. They are simple to use, operate cleanly, and require minimal maintenance.
Hazardous Duty Convection and Blower-Type Heaters
Chromalox hazardous duty convection and blower-type heaters provide comfort, freeze
protection, and moisture protection in areas like switchgear, control rooms,
outbuildings, and pump houses—particularly where the possibility of explosion or fire
exists. Ruggedly designed Chromalox convection and blower-type heaters are UL-listed and
CSA- and MSHA-certified. Models are available for wall or ceiling mounting.
