4CHEMICALPROCESSINGPRECISE HEAT ANDCONTROL FORACCURACY ANDREPEATABILITYChromalox heaters andcontrols are engineered andmanufactured to provideprecise heat and control tohelp ensure the accuracy andrepeatability that is expectedof your process.We control the manufacturingprocess from the firstcomponent to the finishedproduct. Our verticalintegration of productmanufacturing allows tightcontrol of all procedures.We can adjust to meetcustomers’ criticalrequirements. Having controlfrom the very beginning ofevery step of the process,Chromalox can ensure thatthe highest quality isdesigned and manufacturedinto each product and allowsus to produce systems thatare tailored to our customers’needs and requirements.Distillation Column HeatingHeat transfer systems and package electricsteam boilers can be used to indirectly heatdistillation columns. Hot oil systems can achievehigh temperature at very low pressure. Fordirect heating, corrosion-resistant immersionheaters are used.Product Transfer LinesElectric heat trace provides pipe temperaturemaintenance for temperature-sensitive materials.Chromalox offers self-regulating cable andcontrol systems for general-purpose andhazardous locations. Mineral-insulated cableis available for pipe temperatures up to1,100ºF (595ºC).Wastewater TanksLTFX-style immersion heaters providefreeze protection on chemical wastewaterstorage tanks. LTFX heating elements canbe removed without draining the tank.Pump House HeaterUnit heaters ensure that temperatures stayabove freezing in the pump houses. Class 1,Division 1 designs available.Caustic and Cleaning Solution TanksStorage tanks containing chemical cleaningagents are heated with immersion and circulationheaters.Immersion HeatersStainless steel sheathed elementsand thermowells are ideal forprocess water applications.A wide variety of ANSI andcustomized flanges and elementlengths is available with ratingsup to 500 kW. Custom wattdensities available for heat-sensitivematerials. Patented 360ºrotatable housing is availableon to facilitate easyconduit connections.Class 1, Division1 rated.Circulation HeatersHigh-energy efficiency, fast heating,and uniform heat distributionfor numerous plant heating applications.High turn-down capability,tight outlet temperature control,and variable flow rates. Varietyof electrical terminal enclosuresis available to meetthe requirements ofyour application.Class 1, Division1 rated.Evaporator HeatingHeating jackets are heated with thermal fluid orsteam to maintain process-specific temperatureson the inner wall of the evaporators.Chemical Feed TanksImmersion heaters with lowwatt densities preheat chemicaladditives.Electric Steam BoilersConstructed of carbon or stainlesssteel with fiberglass insulation toASME or PED code. Safe, versatile,and efficient energy managementsystems that provide low- or highpressurehot water or steam.Packaged units are completelyassembled and ready to install,needing only a water feed-sourceand electric power hookupto operate fromexisting distributionvoltages, makinginstallation simple.Class 1, Division1 rated.Heat Transfer SystemsOur hot oil and water/glycol systemsare safe, versatile, user-friendlyself-contained heating and coolingpackages that provide direct orindirect process heating. Preengineeredand constructed withcarefully matched components,these systems eliminate componentselection andassembly, andprovide easyinstallation andtrouble-freeoperation.
Electrostatic Precipitator Purge HeatingDuct and circulation heaters warm air to heat thewalls of the precipitator to keep particulate fromaccumulating on the ESP walls.Process Heat ExchangerHeat transfer systems and packaged boiler providethe heat source for process heat exchangers.Heat Trace and ControlsCounteracts the heat loss fromprocess equipment and piping, preventssolution precipitation and theincrease of viscosity or solidificationof product, and provides freeze protection.Chromalox offers a varietyof heat trace cable; temperaturecontrol, monitoring, and managementin one, modular package; andall of the necessary componentsneeded to complete the installation,including splices, power connectionboxes, and waterresistantend-sealterminations. Class 1,Division 1 rated.Control SystemsBasic, low-cost temperature andprocess controllers; monitors andovertemperature controls; sophisticatedcontrol systems. Chromaloxcan design the right system foryour plant’s needs, includingintegration with DCS and PLCprograms. We are the only heatingelement supplier offering acomplete line of controls, controlpanels, and accessories.Boiler Feedwater PreheatingImmersion heaters and circulation heaters preheatincoming water supply to reduce cycling ofboiler, increasing efficiency.Reactor Temperature ControlThermal fluid heat transfer systems provide heating and coolingfor various reactions that require tight temperature control.Temperature ranges from -148ºF to 752ºF (-100ºC to 400ºC),depending on the heat transfer fluid used.Eye Wash and Safety Shower HeatingCirculation and immersion heaters heat andmaintain the temperature of heated water loopsfor eye wash and safety shower stationsthroughout the plant.VaporizersChromalox can design speciallyengineered vaporizers for the mostcorrosive and difficult applications.These vaporizers can heat anythingfrom raw materials, such assilane-based materials, to ammoniafor cell processing, to specialtyheat transfer fluids. Chromaloxvaporizers can be design up toseveral MW.Tank HeatersSpecially designed to fit hightemperatureand corrosiveapplications. Multiple productsdesigned to fit large stationary,small portable, and undergroundtanks for just about any materialsand location.5CHEMICALPROCESSINGBROADESTTHIRD-PARTYAPPROVALWith manufacturinglocations in the U.S.and Europe, Chromaloxhas earned world-wideapprovals andcertifications including,but not limited to,CE, NEC, UL, VDE, cUL, FM,CSA, MSHA, BASEEFA,Cenelec, ASME, PED, ATEX,GOST, and ISO 9001:2008.
