Hot Oil and Water Systems

Chromalox hot oil and water systems are self-contained heating and cooling packages that
provide direct or indirect process heating to temperatures of 750°F (400°C). These systems
meet ASME codes and are pre-engineered to include temperature and power controls,
expansion tanks, heat exchangers, pumps, valves, gauges, and all necessary piping. This
eliminates component selection and assembly. Choose from oil or water temperature control
systems for circulation in a closed-loop process.

. Power ratings: 9 to 5,000 kW(31 to 17,061 kBTU)
. Voltages: 208 to 600 V, 1 or 3 phase

Compact Hot Oil and Water Systems

Chromalox compact hot oil and water systems are fully equipped, portable packages capable
of reaching operating temperatures of 550°F (290°C). Available in a wide variety of sizes,
kW ratings, and voltages for many processes. 

. Power ratings: 4 to 48 kW(14 to 164 kBTU)
. Voltages: 240, 480, and 600 V, 1 or 3 phase

Boilers and Steam Generators

Constructed to ASME, PED, KOSHA, or SELO code of carbon or stainless steel with
fiberglass insulation, Chromalox boilers and steam generators are efficient energy
management systems that provide low or high pressure hot water or steam for industrial
processes and comfort heating. NPT or flanged connections are available.
Chromalox has the engineering expertise to design and manufacture large-capacity
electric boilers to meet a variety of applications.

. Power ratings: 3 to 1,600 kW(10 to 5,459 kBTU)
. Voltages: 120 to 600 V, 1 or 3 phase
. Capacities: Up to 5,000 lb (2,275 kg) of steam/hr @ 250 psig (1 MPa)

Liquid Vaporizers

Chromalox horizontal electric vaporizers are designed for use with Dowtherm,*
Therminol,* and other organic fluids to transfer heat at high temperatures and low
pressures. They are pre-engineered, pre-wired, and pre-piped packages designed for
flexible, dependable, and efficient operation. All units are ASME-certified to 150 psi
(1 MPa) at 750°F (400°C) with 300 Ib construction throughout. Seal-welded element
design eliminates leaks and improves serviceability on the heater. Units available with
over-pressure, process, remote, or skid-mounted controls. Optional NEMA weather and
explosion-resistant enclosures are also available.

. Power ratings: 15 to 1,500 kW(51 to 5,118 kBTU)
. Voltages: 208 to 600 V, 1 or 3 phase

Impedance Heating Systems

Impedance heating employs the "Joule Effect" to produce and directly transfer heat from
the entire circumference and length of pipe to the material being heated. It can be used
for proper temperature maintenance as well as to raise fluid temperature. Utilizing the
pipe itself and minimum equipment, installation is simple. Temperature control is highly
accurate to within ±1°F (=1℃)-and higher watt densities-up to 190 W/in.2 (30 W/cm2)
can be used due to increased velocities with lower pressure drops.

. Power ratings: 1 kW to several MW (3 kBTU to several MBTU)
. Voltages: <50 V (after transformer step-down of 480 or 600 V)
· Temperatures: Up to 2,000°F (1,090°C)
