PROCESS CONTROL CONTROL PROCESS REACTION CHAMBER CHAMBER FLUID FLUID PROCESSING PROCESSING REACTION Fluid temperature temperature uniformity uniformity within within laboratory, laboratory, research, research, and and manufacturing manufacturing operations operations Fluid Application Application A reaction chamber requires gases or liquids to be maintained at an elevated temperature A reaction chamber requires or liquids to be maintained at an for elevated temperature to facilitate processing. The gases size and unusual shape do not allow conventional tapes to or facilitate processing. The size and unusual shape do not allow for conventional insulating heating jackets to be used. Thermowells are built into the chamber tapes to allow or for insulating jackets to monitoring; be used. Thermowells are size built and into length the chamber to allow is heating heating and temperature however, the of thermowells for limited. heating Tight and specifications temperature monitoring; however, the size and length of thermowells is to for temperature uniformity inside the chamber require heat limited. Tight specifications for temperature uniformity inside the chamber require heat be applied externally in addition to internally. A custom water bladder is developed by to the be chamber applied externally in addition internally. A custom bladder is developed by filled the manufacturer with an to elastic material on the water interior surface which, when chamber manufacturer with an elastic material on the interior surface which, when filled will easily conform to the contour of the reaction chamber. The exterior material is a high will temperature, easily conform to the contour of the reaction chamber. The exterior material is a high the water resistant material. The bladder will contain heated water, keeping temperature, water resistant material. The bladder will contain heated water, keeping the surfaces of the reaction chamber at a uniform temperature. surfaces of the reaction chamber at a uniform temperature. Solution Solution BriskHeat cartridge cartridge heaters heaters will will be be used used to BriskHeat to heat heat the the water water within within the the bladder. bladder. Pockets Pockets or “fingers” are built into the exterior material that protrude into the water bladder. Each or “fingers” are built into the exterior material that protrude into the water bladder. Each finger is designed to hold a specific size cartridge heater. Once the bladder is filled, the finger is designed to hold a specific size cartridge heater. Once the bladder is filled, fits fits tightly around the the cartridge heater to maximize thermal transfer and eliminate the material material tightly around cartridge heater to maximize thermal transfer and air gaps. Cartridge heaters are cycled on and off to promote temperature uniformity eliminate air gaps. Cartridge heaters are cycled on and off to promote temperature of the water within the water bladder. The the cycling is also The used to prevent spots the hot material. uniformity of the within bladder. cycling is also hot used to within prevent spots Additional cartridge heaters are inserted into the thermowells built into the chamber to within the material. Additional cartridge heaters are inserted into the thermowells built provide heat to fluids inside the chamber that are further from the chamber walls. These into the chamber to provide heat to fluids inside the chamber that are further from the heaters walls. are not These continually cycled but continually have built-in cycled thermocouples control thermocouples power. chamber heaters are not but have to built-in to control power. BriskHeat’s TB4000 family of high amperage temperature controllers are ideal to use on a single chamber heaters up to amperage 50 amps. temperature In addition to controllers controlling are a single of BriskHeat’s TB4000 with family of high ideal zone to use heat, the TB4000 may be ordered with a high limit switch or with two control zones of up on a single chamber with heaters up to 50 amps. In addition to controlling a single zone 50 amps each. This can with be used in wet or where are of of to heat, the TB4000 may controller be ordered a high limit areas switch or with temperatures two control zones sub-zero with the optional panel heater. An alternative is the MPC2 multipoint control up to 50 amps each. This controller can be used in wet areas or where temperatures are panel. It with can the be used to control systems where multiple sub-zero optional panel larger heater. An alternative is the chambers/zones MPC2 multipoint require control independent control of multiple heaters. panel. It can be used to control larger systems where multiple chambers/zones require independent control of multiple heaters. Additional Solutions BriskHeat offers many options for applying surface heating to chambers of any size Additional Solutions and shape. Mica band heaters with nickel-chromium resistance wire maximize surface BriskHeat offers many options for applying surface heating to chambers of any size and contact and provide uniform heating along the inside surface of the band when used shape. Mica band heaters with nickel-chromium resistance wire maximize surface contact on cylindrical shapes. Custom cloth heaters can be designed to provide both heat and and provide uniform heating along the inside surface of the band when used on cylindrical insulation to your chamber. shapes. Custom cloth heaters can be designed to provide both heat and insulation to your chamber.
